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!

How to calculate the power consumption of the electric boiler?
       The electric boiler uses electric energy as the energy source, uses electric resistance or electromagnetic induction to drive the heat, and when the heat medium of the boiler heats the heat medium water to a certain parameter (temperature, pressure), the external output has the rated working medium (steam or hot water). A thermal mechanical device that meets the needs of industrial manufacturing, production and life.


       Power 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 affect the input cost of the boiler operation; only the cost is controlled below a certain limit. In order to get more benefits.

How to calculate the power consumption of electric boilers?
       We can remember the following sentence: The power consumption of a 1KW electric boiler operating at full load for 1 hour is 1 degree. The 1 ton electric boiler is about 0.7 MW, which is 700 KW. The power consumption of a 1 ton electric boiler operating at full load for 1 hour is 700 degrees.
       However, it should also be noted that this is the power consumption situation of the electric boiler under full load; compared with other types of boilers, the electric boiler is more intelligent and can adjust steam or hot water according to different needs of users. The temperature of the boiler will change. In general, the average power consumption of the electric boiler is about 1/3-1/2 of the full load.

How to reduce the power consumption of electric boilers?
       The method of reducing the power consumption of electric boilers mainly starts from the above four factors that affect the power consumption of the boiler.
       1. Maintain good insulation effect in the boiler room
       The heat insulation measures in the boiler room are properly handled. The heat loss during the operation of the electric boiler will decrease, and the heat energy utilization rate will increase, so that more power is not needed to meet the needs of users.
       2. Changes in the heating environment
       For houses that require heating, the height of the house and the configuration of the heating facilities must be handled properly to meet the optimal heating environment. The heat generated by the boiler operation is directly delivered to the house, reducing heat loss and reducing the power consumption of the boiler.
       3. The situation of the electric boiler itself
       The electric boiler itself must have a certain degree of intelligent regulation and control. According to the user's needs or changes in the environment, the working load in the boiler can be adjusted by itself, and the operating load can be increased when the demand temperature is high, and the operating load can be reduced when the demand temperature is low. Can alleviate the power consumption of the boiler.

When a gas-fired steam boiler is in operation, a series of chemical and physical reactions occur in the furnace. During use, hard and dense scales are formed on the heated surface, which directly leads to a decrease in heat exchange efficiency of the boiler; The effect of corrosion under scale will result in reduced heat absorption of the water-cooled fireplace of the gas-fired boiler, thereby reducing thermal efficiency and wasting input costs.

Another need to clean up the scale is to keep the boiler running for a long time.

The thermal conductivity of scale is only one percent of the steel. Once the surface is fouled by the hot surface, the heat transfer effect is hindered. In order to maintain a certain output of the boiler during use, the temperature on the fire side must be increased. The outlet temperature of the furnace of the gas steam boiler is increasing, which will increase the loss of the gas steam boiler, and the scale in the water wall of the equipment will effectively reduce the heat transfer effect, which is very likely Will cause the temperature of the wall of the water wall to increase, causing the water wall to burst.

Cleaning the boiler becomes even more important. In the process of cleaning, high-efficiency, environmentally-friendly and non-corrosive cleaning agents can be used, which will cause the equipment tubes to reveal the original metallic color and reduce the influence of scale.

Secondly, after the ignition of the gas steam boiler, it is necessary to pay attention to observe the temperature of the furnace and the temperature change of the main steam; when the main steam pressure is rising, if the boiler is ignited, the speed of the rise of the smoke temperature will be significantly slow or not rising, immediately Check the oil gun's fire.

Gas-fired steam boilers produce more or less scale after a long period of operation.

How to purchase a gas boiler with excellent quality? Customers can refer to the following two aspects.

First. Thermal efficiency and boiler capacity
       Compared with the traditional boiler, the high-quality gas boiler is composed of ND steel with a thickness of 28mm, which has stronger heat transfer and corrosion resistance, so the thermal efficiency is also improved. The customer can carefully observe the boiler material during the selection process to confirm whether the performance meets the requirements. In addition, you can also pay attention to boiler capacity, design structure, water flow in the boiler, water level fluctuations and so on. High-quality low-nitrogen boilers are inevitably advanced in thermal efficiency and capacity technology.

Second. The operability and noise intensity
       If you have selected a low-emission, high-heat efficiency gas boiler, you can turn your attention to the boiler operation. The gas boiler has an intelligent control system that can be docked with the intelligent control platform to achieve fully automatic operation. At the same time, attention should be paid to the noise intensity generated during the operation of the boiler, and the boiler with low noise intensity can be included in the selection range.
