At present, atmospheric gas boilers are still used for low-temperature heating and hot water supply. Many hot water boilers also exist in the form of atmospheric pressure. This year's heating season is approaching, and many heating companies that need to use hot water boilers need to purchase large-tonnage atmospheric hot water boilers. So, what problems should be paid attention to in the heating process of atmospheric hot water boiler? Let Zhengzhou Fangkuai boiler manufacturer tell you the answer.

The first thing to emphasize is that hot water boilers have strict requirements on water quality during operation. If the water quality is low, it is very likely to cause damage to the boiler. Therefore, a water softening device will be installed for water treatment during boiler feed water.

Because the water quality is not treated in time, over time, the substandard water components will physically or chemically react with the boiler, which will cause damage to the boiler wall or boiler fouling, which will affect the boiler’s insulation effect and thermal efficiency. In order to ensure this part Loss, the amount of fuel used will increase.

Due to the presence of acid-base substances and oxygen in the water and the chemical reaction of the metal boiler body, the furnace wall gradually becomes thinner and dented, which reduces the strength of the boiler and easily causes safety accidents during operation.

Of course, there will be other hazards, such as the output of the boiler, the normal operation of the boiler water circulation, and the shortening of the boiler life. These are the hazards caused by not using soft water change. The Zhengzhou Fangkuai boiler manufacturer has conducted an investigation. After analyzing the hazard of no boiler water softening treatment, it will be found that if the boiler is to operate with low energy consumption, high efficiency and high safety, the boiler water softening will also make the most important One of the factors, therefore, strict treatment according to standards also needs to be done with caution.

Atmospheric hot water boiler is a relatively common type of heating and heating equipment, which is widely used in many enterprises. Although the internal pressure of the boiler is often higher than that of the high-pressure boiler, the safety performance of the boiler is much higher, but some operations must be strictly observed during use, so as to ensure that it can always operate safely. So, how to ensure safe operation when using atmospheric hot water boiler for heating? Let Zhengzhou Fangkuai Boiler Factory tell you the answer.

First of all, we must ensure that the quality of the purchased atmospheric hot water boiler itself is good and pass the customs, so that users will not be prone to dangerous accidents when using the boiler in the later period. The welding process of the boiler is very important. On the one hand, it is the consideration of the welding personnel's technology, and more importantly, it is responsible for the safety of the later boiler. In the process flow of the atmospheric hot water boiler, welding is also a very important step.

The second thing to note is that the maximum normal pressure value of the normal pressure hot water boiler has been set before leaving the factory. Once a scene that exceeds its pressure range occurs during operation, the user cannot change it at will. You can contact the professional team to pass this Formulate reasonable solutions to this phenomenon to ensure the pressure required by users.

Due to its own particularity, atmospheric hot water boilers are equipped with many security components such as water level gauges, safety valve water level alarms, overpressure alarms, etc. These components must be tested at all times to ensure normality and alertness. It is ensured that in the event of an abnormal phenomenon in the boiler, the inspectors can be alerted quickly to prevent problems before they occur.

Here, Zhengzhou Fangkuai Boiler Factory reminds everyone: in the process of using atmospheric hot water boiler, complying with the use specifications and standards can ensure the safety of the site and personnel on the one hand, and also ensure the safety of the atmospheric hot water boiler on the other hand. It runs smoothly and is relatively convenient.

In the cold winter, only heating can bring us warmth like spring, and hot water can bring more convenience to our lives. Generally speaking, it is more convenient and safer to use atmospheric hot water boiler for heating, which is mainly related to the performance of the boiler itself. What factors should a heating company pay attention to when purchasing atmospheric hot water boilers for heating? Let Zhengzhou Fangkuai Boiler Factory come to answer you for free.

First, determine the purpose of purchasing atmospheric hot water boilers. When purchasing an atmospheric hot water boiler, the different requirements of the operating environment should be considered. If the user only needs heating, he should choose a dedicated atmospheric hot water boiler for heating, and the hot water in the pipeline is recycled through the hot water circulating pump. Reuse the radiator, that is, the radiator, which delivers the heat to every corner; only need to provide hot water, select special hot water, and use the hot water circulation pump to circulate the hot water in the hot water tank to supply hot water; some users also There are two options, so they must choose to add a heat exchanger to the piping system in order to use two atmospheric pressure hot water boilers.

Second, determine the heating area and water consumption of the building. By calculating the circulation volume, determine the heating area or the amount of hot water required for the use field, and design the boiler. Accurate and scientific calculation and design can meet the requirements of use without wasting resources.

Also, determine which fuel is more convenient to use locally. In atmospheric hot water boiler equipment, it is more convenient to choose coal, natural gas, oil, and electricity as fuels, depending on which fuel is more convenient, environmentally friendly and cost-effective to use at the project site.

The above is the list of Zhengzhou Fangkuai Boiler Factory for everyone. The heating industry needs to pay attention to several aspects when purchasing atmospheric hot water boilers. I hope it will be helpful to everyone.

Atmospheric hot water boilers and pressurized hot water boilers are two common types of hot water boilers. The main difference lies in the difference between normal pressure and pressure. So, for users who are new to hot water boilers, how to correctly distinguish normal pressure and pressurized hot water boilers and complete the selection? Let Zhengzhou Fangkuai Boiler Factory answer everyone.

1. Look at the pressure change inside the boiler
       The biggest difference between these two types of boilers lies in the pressures of atmospheric hot water boilers and pressure boilers. For atmospheric hot water boilers, the pressure of the hot water in the furnace is always the same as the atmospheric pressure, and does not change with the change of water temperature; on the contrary, for pressurized hot water boilers, because the steam-water system in the furnace is composed of a sealed structure; As the water temperature rises, pipes and tubes will naturally change.

2. Look at the water level control of the boiler
       In order to realize normal pressure operation, the inlet of the circulating water pump is connected with the outlet of the boiler, and the hot water sucked into the boiler is heated to the user. The user's return pipe and the boiler's water inlet necklace are equal to the water inlet. Atmospheric hot water boiler water level control problem, therefore, the drum and water on the top are still with the open box, water level control problem. However, pressurized hot water boilers do not have water level control problems, which is one of two significant differences.

3. Look at the structural limitations of the boiler
       The structural parameters of atmospheric hot water boilers are much simpler than those of pressurized hot water boilers. Different from the strict restrictions on boiler capacity, parameters and installation location in the structure of pressurized boilers, normal pressure hot water boilers only need to arrange the heating surface reasonably to ensure the reliability of water circulation, and there are fewer restrictions on the structure. It can be designed, constructed and installed to a large extent according to the actual needs of users, which is more flexible and convenient.

The pressurized hot water boiler itself is a device with a certain pressure. If it is not operated in accordance with the safety regulations during operation, accidents are prone to occur, which may cause damage to the boiler. Therefore, all heating users who use pressurized hot water boilers must abide by the relevant regulations and implement the relevant procedures before operating. Zhengzhou Fangkuai Boiler Factory has summarized the following safety operation rules, hoping to help everyone.

1. Check the appearance and gas pressure of the pressurized hot water boiler
       Before preparing to start the boiler, the boiler worker on duty must first perform a thorough inspection, including the appearance of the boiler, valves and connections, and then check the gas pressure. Make sure the pressure is within the normal range, not too high or too low. Check before opening the air supply valve.

2. Check the water supply system of pressurized hot water boiler
       There should be water inside the boiler when it is burning, otherwise it will be dangerous. The fireman should check the water supply system, you can see the water pump, if it is not a normal water discharge valve, it will open the air, know that the water pump can be started, and then open the water supply system for each valve.

3. Check the water level data of the pressurized hot water boiler
       If too much or too little water in the booster boiler will affect the safe operation of the boiler, it is very important to check the water level gauge before starting the boiler, because the function of the water level gauge is to let the operator know how much water is in the boiler at any time. Therefore, before starting the boiler, it is necessary to check whether the position of the water level gauge is normal, but also whether the water level gauge and the water level gauge color plug are in the open position to avoid false water level, and then observe whether there is water shortage.

Pressure-bearing hot water boilers are loved by users due to their reliable operation and high thermal efficiency. The inner and outer plates of the hot water boiler launched by Zhengzhou Fangkuai Boiler Factory have also undergone corresponding pressure test, corrosion resistance test, hydraulic test and combustion test. Ensure the safety performance of the boiler in operation. Many users are not very familiar with the application of pressurized hot water boilers, so let Zhengzhou Fangkuai Boiler Factory tell you the answer.

In fact, pressurized hot water boilers can be used in all places where all kinds of businesses and citizens can be used. The quality of a complete hot water system is affordable, and the operation is easier and more high-end. Mainly because the boiler has the following advantages.

1. The welding process of the pressure hot water boiler is good
       The boiler adopts high-tech technology when welding, which will not cause deformation and cracks in traditional welding, nor will it affect the replacement of the flue pipe, nor will it affect the embrittlement of caustic soda. After a long time of use, the boiler can still be kept in its original state and is not easy to crack.

2. The pressure-bearing hot water boiler is environmentally friendly
       The high-quality, low-cost pressurized hot water boiler does not produce harmful gases such as benzene and methane, which not only ensures the cleanliness of the environment, but also does not emit polluting gases, which is very environmentally friendly. Similarly, it is also suitable for many advanced places and places with stricter monitoring, and can effectively save energy and reduce heating costs.

3. The pressure hot water boiler is reliable, safe and stable
       The pressurized hot water boiler launched by Zhengzhou Fangkuai Boiler Factory uses a large diameter furnace bladder and stainless steel flue gas turbulence strips, and is equipped with a return water lifting device. The outer layer adopts a thicker glass wool insulation layer. Through the cooperation of various system components, the heating speed and heat conversion efficiency can be guaranteed, so its stability is strong.

4. The pressure-bearing hot water boiler is easy to install and easy to use
       The boiler has a complete set of system matching. According to the different use environment and installation location, only need to make fine adjustments to meet the energy saving requirements, so there is no need to worry too much about the installation.

Hot water boilers are mostly used for heating and heating in winter. If a failure occurs during the heating process, the user's hot water will be insufficient and the ambient temperature will be too low, which will affect normal life. Zhengzhou Fangkuai Boiler Factory summarized some common failure causes and solutions of hot water boilers to help everyone run the boiler better.

At present, most of the hot water boilers on the market adopt the structure of membrane water wall. What are the advantages of this design?

1. Since the membrane water wall of the hot water boiler has good sealing performance and better heat preservation effect, it improves the thermal efficiency of boiler operation, thereby providing more heat for production and life per unit time.

2. Because it surrounds the furnace and has good airtightness, part of the furnace wall can be saved with refractory materials, which simplifies the furnace wall structure to a certain extent and reduces the total weight of the boiler.

Many users have reported that the hot water boiler has a low water level during the operation. Zhengzhou Fangkuai Boiler Factory analyzed that it may be due to the water level sensor, the main controller, etc., or the heating system has water shortage. The specific situation needs to be finalized through detailed investigation and then resolved.

If it is a water shortage, replenish water in time after confirmation. If it is said that the water level sensor, controller, etc. have poor contact, then they should be replaced after confirmation. Of course, there will be other reasons. These should be based on the specific situation and take reasonable measures.

When the hot water boiler meets people's heating and heating needs, it is also very important to achieve low-cost operation, so as to avoid waste of resources, but also save an investment cost, and achieve two goals. So, what can be done to ensure energy-efficient operation of hot water boilers? Let Zhengzhou Fangkuai Boiler Factory tell you the answer.

1. The waste heat recovery method is adopted to make full use of the heat after the fuel combustion of the hot water boiler and the waste heat in the flue gas, thereby effectively improving the efficiency of the hot water boiler, saving resources and reducing costs.

2. If possible, make good use of hot water heating. Hot water heating can save at least 20%-40% of fuel.

3. Ensure the insulation effect of the pipeline and effectively prevent heat loss.

At the same time, it should be noted that the amount of scale generated inside the hot water boiler is regularly detected. When the amount of scale reaches a certain level, it needs to be cleaned.

Zhengzhou Fangkuai Boiler Factory suggests that when the controller of the hot water boiler shows "excess scale", the following measures should be taken:

1. Strictly control the feed water index of the hot water boiler, soften it, and make it enter the boiler for use.

2. Arrange the corresponding personnel to descale the boiler regularly to avoid a large amount of fouling deposits and affect the operation of the boiler.

As the level of economic development continues to improve, people's needs are constantly updated, and the requirements for hot water boilers are getting higher and higher. In addition to common heating and heating, hot water boilers also need to supply processing and production. If you want to purchase cost-effective hot water boilers, you must not ignore these three important parameters, and let Zhengzhou Fangkuai Boiler Factory tell you the answer.

1. Power of hot water boiler
       For hot water boilers, power refers to the heat provided by the boiler per unit time. Its choice is related to the input and cost, and they are directly proportional. If the selected power is too large, it will cause input costs and Later operating costs will be higher.

2. Water supply and return water temperature of hot water boiler
       Generally, the water supply and the temperature of the hot water boiler will be determined according to the heating requirements and the temperature of the heating area. For example, the adjustment method of heating in winter can be to change the quality adjustment of the water supply temperature and change the amount adjustment of the boiler circulation flow rate, so it will depend on the actual situation.

3. Design pressure of hot water boiler
       This can be a simple comparison reference. Generally speaking, the nameplate pressure of the hot water boiler is designed by the boiler manufacturer according to the national standard GB3166-82 hot water boiler product parameter series. It represents the highest working pressure of the hot water boiler. The actual working pressure of the hot water boiler is determined by the working pressure of the circulating pump, which is generally lower than the nameplate pressure.

It can be seen that if you want to purchase a cost-effective hot water boiler, the above parameters must be considered, so that we will have an advantage in the later operation and maintenance of the hot water boiler.

During the operation of the hot water boiler, if there is a sudden power failure during the operation of the boiler, the pump is stopped, the circulation is interrupted, the temperature of the water at the outlet of the boiler rises sharply, the over-temperature alarm does not give an alarm, and the boiler staff fails to detect a series Under the circumstances, the vaporization phenomenon of the hot water boiler is likely to occur, which is very unfriendly to the boiler itself and the user. Zhengzhou Fangkuai Boiler Factory summarized some 3 measures to prevent the vaporization of hot water boilers, which can help everyone better avoid vaporization of hot water boilers.

1. During the operation of the hot water boiler, the fireman must strengthen inspections and inspect carefully, and deal with it in time if abnormalities are found.

2. The smart test of the monitoring system must be done in place, and at the same time, it must be equipped with alarm equipment when the pump is abnormally stopped, and frequent maintenance.

3. Strengthen the repair and maintenance of hot water boilers, especially the more important parts such as the rotating parts of the water pump and bearings.

Of course, the best prevention is the professionalism and rigorous attitude of the furnace staff, in addition to the power of the equipment. After all, the machine is controlled by humans, so the furnace staff must have a correct attitude and operate the boiler stably.

In the operation of gas-fired hot water boilers, it is necessary to deoxygenate the feed water. The main reason is that oxygen is the main corrosive substance in the boiler water supply system. The oxygen in the water supply system should be removed quickly, otherwise it will corrode the boiler water supply system and components, and the corrosive iron oxide will enter the boiler, deposit or adhere to the boiler On the pipe wall and heating surface, insoluble but poor heat transfer iron scale is formed. Corroded iron scale will cause pits on the inner wall of the pipe and increase the resistance coefficient.

Therefore, in order to ensure the safe operation of the boiler, it is necessary to deoxygenate the boiler feed water; in the national standard "Industrial Boiler Water Quality" (GB1576-2001), the country puts forward strict requirements on boiler water quality, requiring evaporation Steam boilers with a capacity greater than 2t/h and hot water boilers with a rated power ≥4.2MW must be deoxygenated.

Zhengzhou Fangkuai Boiler Factory has summarized some operating skills when deoxygenating the feed water of gas-fired hot water boilers, hoping to help users better use the boilers.
       1. Thermal deaeration
       Thermal deoxygenation can not only remove oxygen in water, but also carbon dioxide or other gases. The deoxygenated water will not increase the salt content, nor will it increase the dissolved amount of other gases, the operation control is relatively easy, and the operation is stable and reliable.
       2. Vacuum deaeration
       Vacuum deaeration is performed at lower than atmospheric pressure (vacuum degree 600~700mmHg). It belongs to low temperature deaeration. Then the so-called vacuum deaeration shows one thing, that is, the degree of vacuum must be maintained. The quality of vacuum deaeration effect is closely related to the degree of vacuum.
       3. Chemical deoxygenation
       Chemical deaeration is also divided into different types, steel scrap deoxidation; sodium sulfite deoxidation; hydrazine deoxidation; resin deoxidation, etc. Different types of chemical deaeration methods have different characteristics. Of course, the water temperature requirement of chemical deaeration is greater than 70°C, 80~90°C has the best effect, and 20~30°C has the worst effect of deoxygenation.
       4. Analysis and deaeration
       The working principle of deoxygenation is to intensively mix and contact the oxygen-free gas with the feed water to be deoxygenated, so that the oxygen dissolved in the water is desorbed into the gas, so that the feed water achieves the purpose of deoxygenation through such circulation.

You can choose the appropriate deaeration method according to your own use of gas-fired hot water boiler to achieve the purpose of deaeration.

Compared with gas-fired steam boilers, gas-fired hot water boilers have a higher safety factor, especially atmospheric and vacuum hot water boilers, but this does not mean that the use of gas-fired hot water boilers is absolutely safe. Improper operation or poor quality of the boiler itself, the gas-fired hot water boiler (steam) water system also has the possibility of explosion. Zhengzhou Fangkuai Boiler Factory summarized some measures to ensure safer operation of gas-fired hot water boilers, hoping to avoid dangerous situations in the boiler.

First of all, in terms of fuel, natural gas has the flammable and explosive properties, so that the gas-water system or delivery system of gas boilers may explode.

In comparison, the latter is a chemical explosion, and the probability of occurrence may be greater. Therefore, on the basis of protecting the former, the focus of the work should be on the safety control of the gas system and resolutely prevent gas safety accidents. If it happens, the following aspects should be taken as the basis for the key protection work:
       1. Strengthen the safety education and skill training of furnace workers
       Safety education and training mainly focus on the basic structure and operating principles of gas-fired hot water boilers, the chemical and physical properties of natural gas, the links that are prone to safety accidents in the operation of gas-fired hot water boilers, the handling of gas accidents and emergency plans, etc. Aspects of training. In addition, in order to avoid the disadvantages of operating gas-fired hot water boilers due to the low cultural quality of the operators, it is necessary to strengthen the skill training of the operators and strictly supervise them to ensure that each operator is proficient in operating skills.
       2. Equipped with necessary gas leak detection equipment to strengthen the active inspection of the gas transmission system.
       Due to a series of problems such as the laying distance of the official website, if there is a gas leak on the way, it will cause a safety accident if it encounters fire factors such as open flames, static electricity, and lightning. Therefore, we must pay great attention to prevent problems before they happen.
       3. Develop emergency plans for gas leakage accidents and organize emergency plan drills regularly.
       Simulate actual combat drills of emergency plans should be carried out regularly. In the simulation of actual combat exercises, it is necessary not to go through the scene and deal with it falsely. It is necessary to be down-to-earth and implement conscientiously, so that the trainees can be fully exercised and cooperate with each other.
       4. The normally open channel of the boiler room of the gas-fired hot water boiler must have access control to effectively prevent irrelevant personnel from entering the boiler's heavy ground at will, which may cause unsafe factors.
       5. The sensitivity and reliability of the gas leak monitoring device and the exhaust system of the gas hot water boiler should be tested on a regular basis, and the fire department should also actively cooperate with the fire department to do the annual inspection of the fire safety alarm device on a regular basis.

The safety of gas-fired hot water boilers during operation is a key factor that we need to consider during the operation. We must conduct timely maintenance and testing. Once problems occur, we will solve them in time, and strive to reduce hidden safety hazards during operation. Lower.
