Enabling the operation of energy saving and emission reduction of industrial boilers can save a large amount of investment costs for enterprise units, and it can also save the tedious inspection of environmental protection departments.

For industrial boilers, whether they can achieve energy conservation and emission reduction depends on these measures. Zhengzhou Fangkuai Boiler Company will come to explain one by one for you.

1. Reconstruction of fuel supply device
       For oil-fired gas boilers, it is necessary to effectively control the ratio of fuel and air to achieve sufficient combustion. There should be neither too much nor too little fuel.

2.Transformation of combustion system
       The traditional industrial boiler combustion method is diffusion combustion. Such a combustion method is likely to cause uneven combustion temperature inside the boiler furnace, which may easily cause insufficient combustion of fuel, resulting in waste of fuel energy. Zhengzhou Fangkuai Boiler Co., Ltd. changed the combustion system of the industrial boiler to full premixed combustion. This type of combustion uses fuel and air to be mixed in advance, and then close to the combustion device, which can ensure that the temperature in the furnace is uniform throughout and avoid fuel combustion. Non-uniformity occurs.

3. Rebuild the overall structure of the boiler
       Many industrial boilers do not adopt a reasonable design structure when they are manufactured, which will also lead to a reduction in the thermal efficiency of the boiler and ultimately fail to achieve the purpose of energy saving.

4. Reconstruction of boiler auxiliary machine
       The frequency conversion combustion technology can be used to achieve dynamic and intelligent combustion of the boiler, which not only saves the trouble of the boiler worker every time adding fuel, but also makes the boiler and fuel delivery more compatible.

5. The automatic control system is adopted to adjust the output heat of the boiler in real time to achieve the purpose of energy saving.

6.Recovery condensate from boiler operation
       The industrial boiler can increase the operating efficiency by more than 10% after adding condensing technology, which is very energy efficient. However, such a boiler will also generate a lot of condensed water after operation. If the user does not use this part of condensed water, it will also cause energy waste. The temperature of the condensed water is generally around 100 ° C, which is very low compared to the boiler temperature, but there is also a lot of heat. You can recover this part of the condensed water and participate in the boiler for reuse.

7.Boiler replacement, replacement of old boilers with new boilers
       If the operation efficiency of the original boiler is very low, or the pollutants emitted are seriously exceeded, and the service life is long, we do not recommend that you continue to use or rebuild the original boiler. After all, the cost of such a boiler reconstruction It is also very high, and it is better to directly purchase a new fuel-gas industrial boiler that has high energy efficiency and low nitrogen emissions.

Performing a water pressure test before the boiler is officially started can grasp the problems existing in the boiler early and deal with them in a timely manner. Take oil-fired gas boilers for example.

The hydraulic pressure test of oil-fired gas boilers is generally divided into a hydraulic pressure test and a super-hydraulic test of rated working pressure. The overpressure test pressure of the boiler body is 1.25 times of the rated working pressure of the boiler shell or the rated pressure plus 0.4 MPa.

If one of the following situations occurs, our oil-fired gas boiler also needs to perform an overpressure water pressure test.
       1. Before the newly installed boiler starts trial operation;
       2. After the boiler's pressure parts have undergone major transformation or replacement;
       3. The boiler in operation is performed every six years (combined with overhaul).

If one of the following situations occurs, our oil-fired gas boiler needs to perform a working pressure and hydraulic test.
       1. Generally, after large or small repairs or rush repairs, the hydraulic pressure test of the working pressure is performed after the repairs;
       2. If the furnace is shut down for more than 30 days, a hydraulic pressure test of working pressure must be performed before ignition.

Previously we said that it was better to perform a hydraulic test for the sake of safety. However, whether it is a steam boiler or a hot water boiler, after the boiler is installed, a hydraulic pressure test (that is, water pressure) must be performed. After long-distance transportation, loading, unloading, and installation, collision and damage are unavoidable. Boiler defects can be found through hydraulic tests, and appropriate measures can be taken in time to ensure the safe operation of the boiler.

Full water is a certain danger for the steam boiler in operation. Once the steam boiler is full of water, the output steam will bring a large amount of water, or the water hammer in the steam pipeline will occur. To reduce the steam quality, it will also affect the normal gas supply of the boiler. In addition, if the consequences are very serious, it is the fouling of the superheater in the steam boiler, which causes damage to the boiler. If the boiler operators do not find and solve in time, the boiler is likely to have more dangerous accidents. So, when the steam boiler is full of water, how do you quickly solve it? Listen to the technical lecturer from Zhengzhou FANGKUAI Boiler Co., Ltd. to explain in detail for everyone, how to deal with steam boilers full of water quickly to minimize damage.

In order to keep the steam boiler away from water-filled accidents, we must first start from Sheung Shui.

For steam boilers, the hardness of the feed water is mainly required, which should be within 0.03 mmol / liter. In addition, in order to avoid the full water accident of the steam boiler, the standards on the superheater must be strictly in accordance with the requirements, etc., to carry out specific operations in this regard.

In a steam boiler, if there is a superheater, it can produce dry steam. However, if the condition inside the boiler deteriorates, it can only be saturated with steam.

For the various situations that the steam boiler will encounter during operation, the technicians of Fangkuai Boiler just gave a brief introduction to everyone from the situation of full water. I hope that it can help everyone to improve their knowledge and understanding of the steam boiler. We can apply what we have learned from time to time to avoid safety accidents in the boiler.

It is believed that many user units need to use boilers as a source of heat to drive the demand for heat production in the factory or in the living. But if you want to make the boiler work better for us, you need to pay special attention to the installation problem. Because even if the boiler is better, if there is any problem in the installation, the operating efficiency of the boiler will be greatly reduced.

There are a lot of issues that we need to consider before installing the boiler. The first is the consideration of the installation location. Because the boiler is used to provide thermal energy, the surface temperature is very high, so it should be avoided to contact the human body when installing the boiler. The choice of the installation location should be as far as possible at the corner or on the side, so as not to hinder the passage of people, this is the first consideration when installing.

Another problem to be noticed is ventilation, because the boiler will generate a lot of fumes during use. Even if each boiler has a special exhaust facility, it is still necessary to pay attention to ventilation during installation. Attention to ventilation has two advantages, the first is to facilitate the emission of smoke, the second is to maintain the temperature inside the boiler room, so that the temperature is too high, making people feel uncomfortable.

The horizontal steam boiler is a relatively classic type in the current boiler market. It adopts the horizontal design structure. The arched tube plate and the threaded pipe form a drum. The heat transfer efficiency is high, the pressure is fast, the output is sufficient, and the load is overloaded. Strong ability, not easy to accumulate in the pipe.

The welding joint of the horizontal steam boiler is treated by large-scale machining and special processing in the high-temperature zone tube bundle. The manufacturer will also carry out flaw detection treatment in the later stage to ensure that the weld is 100% qualified before the boiler can be shipped, which greatly guarantees the boiler. safety.

The horizontal steam boiler has a compact structure, small size and size, saves capital investment, and is easy to install. It can be operated by connecting valves, water and electricity and pipelines. Stable operation, convenient adjustment, unique anti-leakage design, long sealing time.

The dust, sulfur and nitrogen oxides contained in the flue gas of horizontal steam boilers are all pollutants that pollute the atmosphere. When not purified, the emission index can reach several times to several tens of times of the environmental protection regulations. Measures to control the discharge of these substances include pre-combustion treatment, improved combustion technology, dust removal, desulfurization and denitrification. The use of high chimneys only reduces the concentration of pollutants in the atmosphere near the chimney.

In the current boiler market, there are more and more types of gas-fired boilers using energy-saving technologies, and condensation technology is one of them. By adding a condenser at the end of the boiler, a large amount of latent heat is released when the high-temperature flue gas passes through the condenser, and is supplied to the boiler for reuse.

Condensed water refers to liquid water formed by water vapor (ie, gaseous water) during condensation, which is a physical change. Today, Fangfang Boiler will unveil the treatment of condensate for you!

1. There are two main reasons why gas boilers produce flue gas condensation water.
       (1) The water vapor in the flue gas condenses into water when it is below the dew point temperature;
       (2) The boiler has high thermal efficiency and low exhaust gas temperature. The exhaust temperature of the boiler under the rated load is slightly higher than the dew point temperature of the flue gas. Under the condition of long-term operation with low load, the flue gas temperature is lower than the flue gas dew point temperature, and condensed water will flow out from the tail heating surface of the boiler. , the boiler is discharged from the rear smoke box.

2. What are the components of gas boiler flue gas condensate?
       The gas boiler generates condensed water during operation. The main components of the condensed water include: water produced by natural gas combustion, sulfur oxides formed by combustion of sulfur in natural gas impurities, acidic substances formed in water, and nitrogen in the air under high temperature conditions. The nitrogen oxides formed by the oxygen in the air are dissolved in the acidic substances generated by the water.

3. There are too many condensed water in the gas boiler. How to deal with it?
       When the gas boiler is in operation, especially when the cold furnace is started, the flue gas condensed water is often generated at the heating surface of the boiler tail and the rear smoke box, so that the furnace worker mistakenly believes that the boiler leaks.
       The condensed water generated by the gas boiler during operation should be discharged out of the boiler in time, because if the condensed water accumulates too much, it will affect the normal operation of the boiler, which will cause water leakage at the connection between the rear smoke box door cover and the rear smoke box flange.
       Specific measures include:
       (1) The boiler is provided with a condensate drain at the rear smoke box
       In order to enable the condensed water to be discharged in time, the discharge port is generally not provided with a valve, and a water seal should be provided to prevent the flue gas from escaping from the tube.
       (2) Smoke box outlet setting takeover
       After the boiler flue gas exits the smoke box and enters the chimney, since the heat dissipation of the chimney is still cooling, the water vapor in the flue gas is still condensed on the chimney wall, forming small water droplets flowing down the chimney wall, so it should be in the smoke box. The outlet is set to allow the condensate to drain into the trench or any drainage system.
       Excessive condensate of gas boiler flue gas should cause concern. Although condensed water production is unavoidable, excessive condensed water is generated, which will inevitably affect the safe operation of the boiler.

4. Does the flue gas condensate of the gas boiler have any pollution problems? Do you need special treatment? According to the composition analysis of the condensed water, we can know that the condensed water is acidic. The pH value of condensed water is mainly related to the sulfur content of natural gas. At present, domestic natural gas is mainly from four atmospheric fields, and the sulfur content is unknown. If you are interested, you can buy some PH test paper to measure the PH value of the boiler condensate.
       In general, the condensate pH of a cast aluminum heat exchanger is slightly higher than that of stainless steel (equivalent conditions).
       But although the condensate has a certain acidity, it has little effect on the environment. Do not believe that the condensate is collected in a bucket, added with alkaline substances and then poured into the sewer.

Because the condensate is somewhat acidic, it is diluted very lightly after entering the sewer system, and its effect is minimal. Moreover, today's residential sewers are made of plastic pipes, and even condensed water that has not been diluted will not affect the pipeline.

So we can ignore the environmental impact of this condensate. There is no need for special handling.

Controlling boiler operating costs is a particular concern for units using gas boilers. In the operation of gas boilers, enterprise users can control the production cost by improving the combustion efficiency and thermal efficiency of the boiler. One of the key factors is that we must choose a powerful boiler manufacturer to purchase a boiler with excellent performance and advanced technology, and then reduce production by reducing the fuel consumption of the gas boiler without affecting the use effect. The purpose of the cost. The following are the recommendations given by the engineers of FANGKUAI Boiler.

1. Flue gas condensation heat recovery system: This system mainly reduces the heat generated by the gas boiler during the smoke exhaustion, and reduces the gas consumption without affecting the boiler's own thermal efficiency.

2. Climate compensation system: This system is adjusted according to indoor and outdoor temperature changes, so that the overall heating, heat release and building of the gas boiler are consistent, preventing excessive temperature difference between indoor and outdoor.

3. Heating system hydraulic balance: the average heating quality of all users, using this system, can directly save about 10% of energy.

4. Heating centralized control system: install the number of boilers according to the required heat load, and evenly distribute the heat load between the gas boilers, so that all boilers can reach the optimal state. The technology in this area is not mature enough in China. If you want better results, you can use imported boilers.

As a manufacturer specializing in the production of gas boilers and electric boilers, FANGKUAI Boiler has gone through more than 20 years of development. The energy-saving gas-fired boiler produced by the company adopts the technology of first pre-expansion and then full-welding, and finally re-expanding, which not only prevents the pipe gap corrosion, but also enhances the welding strength; uses a high heat transfer coefficient thread pipe to enhance the convective heat transfer effect. Reduce the exhaust gas temperature and improve the thermal efficiency of the boiler. With the industry-leading gas boiler products and perfect after-sales service, FangFeng Boiler is recognized and trusted by many gas boiler users.

Gas-fired boilers use gaseous fuels as the main energy source to meet the needs of industrial manufacturing, production and life by outputting high-temperature steam or hot water.

Air consumption is an important indicator for assessing the overall quality of gas boilers. It is also one of the standards that users measure when purchasing boilers. This data will directly determine the input cost of the boiler operation. Only when the cost is controlled below a certain limit can the data be obtained. More benefits.

How to calculate the gas consumption of a gas boiler?
       Gas consumption = Gas boiler power /Fuel calorific value / Gas boiler heat value utilization.
       For example, we operate 1 ton gas boiler for 1 hour (full load). The boiler output is 600,000 kcal (fixed value), the natural gas calorific value is 36.22 MJ/Nm3 (fixed value), and the thermal efficiency is 92% (non-fixed value). According to the actual situation of the boiler, the calculation is carried out.


       Then, the gas volume required for the operating hours of a 1 ton natural gas boiler = 0.7 MW * 3600 s / 36.22 MJ / Nm3 / 92% = 75 m3 / h.
       Note: The actual power of the boiler is generally not equal to the rated power, so the consumption of gas is only a rough estimate. The specific data depends on the load of the boiler during actual operation.

What are the factors that affect the gas consumption of gas boilers?
       After obtaining the gas consumption data of the gas boiler, we also need to know what factors affect the gas consumption of the gas boiler.
       1. Boiler heating area
       Generally speaking, the larger the heating area is occupied in the whole boiler, the more heat is transferred to the boiler by the fuel combustion, and the fuel utilization rate is improved.
       2. Fuel calorific value and price
       The calorific value of different types of fuels will also vary. The calorific value of natural gas combustion is 36.22 MJ/Nm3, and the calorific value of liquefied petroleum gas is 46 MJ/Nm3; however, fuel costs should also be considered.
       3. Boiler thermal efficiency
       The thermal efficiency of the boiler is also closely related to the heating area. The larger the heating area, the better the heat transfer effect, which will increase the boiler thermal efficiency linearly, make the fuel utilization more complete, and the gas consumption cost less.
       4. Boiler output
       The output of a 1 ton boiler is 600,000 kcal, and this data is fixed.

How to reduce the gas consumption of gas boilers?
       There are two main factors that cause high gas consumption in gas boilers. One is the large boiler load; the other is the low thermal efficiency of the boiler. To reduce air consumption, we must start from these two aspects.
       1. Influence of boiler load
       In the absence of measuring instruments, we measure the heat output according to conventional knowledge. When the user's demand for the boiler is unstable, the boiler consumes more heat and the load increases.
       2. Influence of boiler thermal efficiency
       There are many influencing factors in terms of boiler thermal efficiency. We list some common points. You can check against your own boiler equipment.
       (1) The water quality of the boiler feed water is not good, and a lot of scale is accumulated after long-term operation, and the heat transfer efficiency of the heated surface is lowered. The thermal resistance of scale is 40 times that of steel, and the 1mm scale will increase fuel consumption by 15%.
       (2) Ashing on the outer surface of the heated surface also increases fuel consumption. The furnace can be turned on to check the ash scale, or it can be determined by detecting the exhaust temperature.
       (3) The boiler has a serious air leakage. Excessive cold air enters the furnace, and the oxygen content of the flue gas rises. When the smoke oxygen meter detects that the oxygen content of the flue gas exceeds 8%, excess air will appear and the heat loss will increase.
       (4) The gas quality is lowered and the concentration is lowered. This requires a professional boiler technician to carry out a specific analysis.
       (5) The burner automatically adjusts to failure. The burner mainly controls the combustion condition by automatically adjusting the "air-fuel ratio". If the sensor or computer program is unstable, although the combustion is normal, it will cause "chemical incomplete combustion heat loss". The combustion flame can be observed, the red fire represents poor combustion, and the blue fire represents good combustion.
      

The condensing gas boiler produced by FANGKUAI Boiler adopts advanced condensation technology to set up a condensing recovery device near the flue. When the high-temperature flue gas passes through the device, the latent heat part encounters the condensed water to release heat, which is provided to the boiler for absorption again. The thermal efficiency can be It is 98% high; it can save the company the fuel input cost of 50,000 to 100,000 yuan depending on the boiler capacity and maintenance quality.

Compared with traditional oil-fired boilers and coal-fired boilers, the advantages of gas-fired boilers are obvious, mainly reflected in the following aspects:
       1. The cost of manual and water-consuming electricity for gas boilers is low.
       2. The promotion of flue gas energy-saving or condensation technology in the tail of gas boilers will further increase its thermal efficiency. When the exhaust temperature of gas boilers is reduced below 80 °C, the efficiency can reach more than 95%.
       3, clean and environmentally friendly, the boiler occupies a small area, the failure rate is low, can significantly improve the use of the unit's on-site environment, the supply of sufficient and low prices, environmental requirements, high regional costs and other relative advantages.
       4. Since the boiler uses natural gas as a clean energy source, it does not generate soot and dust in the furnace during combustion, and its operating life is longer than other types of boilers.

However, due to its environmental advantages, natural gas has become more and more widely used in primary energy. The contradiction between supply and demand and the law of value will inevitably lead the country to take action and be linked to other primary energy price fluctuations. In addition, the shortage of natural gas and the incomplete construction of pipelines in some areas are also the reasons for its further promotion.

On the whole, the advantages of using gas boilers outweigh the disadvantages, and the promotion and use of gas boilers is still the trend of the times. As a professional supplier of gas boilers, FANGKUAI Boiler has more than 20 years of experience in the research and manufacture of gas boilers. In 2014, the low-nitrogen gas boilers of the APEC conference venues that were of national concern were provided by Fangfeng Boiler. The first low-nitrogen gas boiler put into use has made outstanding contributions to the technological innovation of gas boilers.

Faced with so many boiler manufacturers in the market, how to choose the right equipment? How many boilers do you choose? How big is the boiler? Is the hot water boiler or steam boiler? Is condensation or non-condensation? FANGKUAI Boiler manufacturers will answer you one by one.

1. How many boilers are selected?
       When buying a boiler, we must consider that there is an emergency backup plan when a boiler fails. If your company has a high demand for boilers, we recommend that you purchase two boilers at a time, one for each.
       Especially when using boilers for heating, there should be no less than two units. When one of them stops for some reason, the design heat exchange capacity of the remaining boilers should meet the requirements of the owner to ensure the heat supply.
       In cold areas and severe cold areas, when there is a boiler failure, the total heat supply of the remaining boilers is guaranteed to be 65% and 70%. If Beijing is heated by 65%, it can be supplied to 8 to 9 °C, and if it is heated to 70% in Harbin, it can be supplied to about 6 °C. In this way, even if there is a boiler failure, it is warmer than the winter in the south.

2. How big is the boiler?
       We all know that when selecting the boiler tonnage, we should choose the heat load according to the actual demand of the enterprise, but we can't simply calculate how much heat load to choose a large boiler.
       This is because the efficiency of the boiler is reduced when operating at low loads. We recommend that the actual operating load of the boiler should not be less than 50%.
       For example, hotels, heating in winter, only need to supply sanitary hot water in summer. If the boiler is selected according to the total load, then when the hot water is only taken in the summer, the operating load of the boiler is very low and the efficiency is also reduced. Therefore, the heat load of each application should be calculated first, and then the capacity selection should be carried out according to the use situation. Such system investment is saved, the system is simple, and the mutual compatibility is good.
       In addition to the heat load of steam in the kitchen, laundry, high-temperature disinfection and humidification of air conditioners in winter, the rest of the heat load should be a hot water boiler.

3. Choose a steam boiler or a hot water boiler?
       The traditional heating method uses a single steam boiler as a heat source, and then uses a plate for heat exchange to be used for hot water. Although this is convenient, the secondary heat exchange loses a lot of heat. Therefore, Fangfeng boiler manufacturers recommend to everyone: heating, sanitary hot water, process hot water, etc. use hot water boilers for direct hot water supply, where steam is needed (food processing, hospital disinfection, chemical production, etc.) using steam boilers . Steam can be used to exchange heat unless the total amount of hot water used is small.

4. Condensation or non-condensation?
       Condensing boilers should be used when the design return water temperature of the heating system is less than or equal to 50 °C.
       The condensing boiler recovers the heat from the flue gas, which improves the efficiency of the boiler, but not all places apply to the condensing boiler.

Because of the use of natural gas as a fuel gas boiler, the dew point temperature of the flue gas is 55 ° C (the temperature of the water vapor turns into dew point), when the system return water temperature is higher than 50 ° C, the condenser can not function. Therefore, the condensing boiler can achieve energy saving only when the return water temperature is less than or equal to 50 °C.

As the name suggests, oil-fired boilers use oil fuels such as heavy oil and light oil to transport hot water or steam to the outside world, providing power to all industries in which the society produces and lives. The main features of the oil-fired boiler are energy conservation, environmental protection, and intelligent operation. The better the environmental protection effect of the boiler, the lower the gas consumption, the less the operating cost of the boiler. Regarding how to calculate the fuel consumption and fuel consumption of oil-fired boilers, many users are confused, FANGKUAI Boiler will answer your questions.

How to calculate the oil consumption of oil boiler?
       Oil consumption = boiler output / Fuel calorific value / Boiler thermal efficiency;
       For example : Oil consumption of 1 ton oil fired boiler
       1. The output of a 1 ton oil-fired boiler is 600,000 kcal;
       2. Assume that the boiler uses diesel as an energy source with a heating value of 42.42 MJ/KG;
       3. The boiler thermal efficiency is calculated according to 92%;
       The fuel consumption of a 1 ton oil boiler = 600.000 kcal 92% ÷ 42.42 MJ / kg = 65 KG.


       The above formula is applicable to oil-fired boilers under rated operating conditions, which is an ideal value. However, in the actual operation of the boiler, the operating load and pressure have changed, and even the operation mode of the furnace workers is inconsistent, which will affect the fuel consumption of the boiler. Therefore, the fuel consumption of oil-fired boilers cannot be generalized.

How to reduce the oil consumption of oil boilers?
       The decisive factors affecting the fuel consumption of the fuel boiler itself are: boiler heating area, fuel calorific value, fuel purity, boiler convection heating area, boiler radiation heating area and so on.
       1. The heating area of the boiler is inversely proportional to the fuel consumption. The larger the heating area, the less fuel consumption.
       2. The fuel calorific value is inversely proportional to the fuel consumption. The higher the calorific value of the fuel, the less fuel consumption.
       3. The fuel purity is inversely proportional to the fuel consumption. The higher the fuel purity, the higher the heat value and the less fuel consumption.
       4. The convection heating area of the boiler is inversely proportional to the fuel consumption. The larger the convection heating area of the boiler, the less the fuel consumption.
       5. The radiation heating area of the boiler is inversely proportional to the fuel consumption. The larger the radiation heating area of the boiler, the less the fuel consumption.
       In addition to the boiler itself, the fuel consumption of the oil-fired boiler is closely related to the furnace experience of the furnace. Not only the fuel consumption of the boiler, but also the safe operation of the boiler is also very important. Therefore, the relevant state departments stipulate that the furnace workers who are on duty must have the certificate of the furnace, which is responsible for the users, the furnace workers, and the society.

How to properly install the boiler to ensure the normal operation of the boiler later? Don't worry, FANGKUAI Boiler not only produces high-quality boilers, but also has high-quality after-sales service. We will send professional technicians to guide you on how to properly install the boiler.

First of all, to investigate the installation environment of the boiler, the layout of the boiler room should be approved by the local quality and technical supervision department before construction. The boiler room should be installed in a place where ventilation, heat dissipation, smoke emission and operation are convenient, and it is not easy to approach. Explosive and explosive materials, electrical installation should be installed by professional and technical staff according to the relevant national standards, N and L lines must not be wrong. When using gas as fuel, electrical explosion-proof devices should be installed, and the switchboard should be more than 6M away from the boiler body.

Secondly, if your boiler is an electric steam boiler, you should pay attention to the installation of the ground wire, which is related to the later use safety. In order to install a safe and reliable grounding wire, the grounding wire should be piling near, the depth is greater than or equal to 1 m 5, and the grounding cable gland should be sintered on the grounding pile head. In order to prevent rust and moisture, the joint should be 100mm above the ground. The chimney of the boiler to be vented should extend outwards and the exit should be 1.5 to 2 m above the boiler. After installation, report to the local special equipment maintenance department. It can be used after being approved by the relevant part of the acceptance and receiving the boiler use certificate. Steam generators with a volume of less than 30L or a steam pressure of less than 0.1 MPa are within the national inspection-free scope, that is, they do not need to be used for boiler use certificates.

According to the installation steps of the steam boiler prepared by Fangfang Boiler, I believe that you will be able to successfully install the steam boiler successfully!
