What is the price of an 8 ton gas steam boiler?

The 8-ton gas-fired steam boiler refers to boiler equipment that can output 8 tons of high-temperature steam per hour, and is commonly used in industrial fields. Many users are not familiar with the selection of gas-fired steam boilers. Facing the numerous boiler manufacturers and boiler types on the market, it is easy to feel confused. Zhengzhou Fangkuai Boiler Factory has recently received inquiries from many users. I am very interested in the price of the boiler. Today, I will give you a unified answer.

There are many factors that determine the price of an 8-ton gas-fired steam boiler, such as boiler model, internal structure, operating efficiency, pollutant emissions, service life, and so on. The 8-ton gas-fired steam boiler launched by Zhengzhou Fangkuai Boiler Factory has two models, WNS and SZS. The operating efficiency is above 98%, and the pollutant emission is as low as 18 mg/m3, which is one of the best in the entire boiler market. Therefore, it has also been loved by the majority of users and friends. The current price of this type of boiler ranges from 60,000 to 70,000 US dollars.

The technical engineer of Zhengzhou Fangkuai Boiler Factory also suggested that everyone should pay more attention to the superheater and reheater inside the boiler. These two accessories are important.

Their function is mainly to discharge the accumulated air, part of the superheated steam and reheated steam when the boiler is started, and to ensure a certain flow rate of the superheater and reheater to cool the pipe wall. In addition, when the boiler pressure rises or in an accident state, the steam and pressure are discharged together with the safety door to prevent the boiler from overpressure. During the start-up process, it can also increase the exhaust steam volume and slow down the boost speed. When necessary, the exhaust steam can also adjust the temperature difference between the two sides of the steam. It can act as an air door when the boiler enters and discharges water. For the reheater to exhaust steam, when the secondary bypass cannot be put into use, the primary bypass can still be used to vent steam to the reheater and exhaust to the empty exhaust valve to protect the reheater effect.

Market price positioning of WNS model 10 ton gas-fired steam boiler

In the field of gas-fired steam boilers, WNS model is a relatively common type of gas-fired steam boiler. The full name of WNS is horizontal, internal combustion, and room-fired boiler equipment. The obvious characteristics of this type of boiler are the reasonable utilization of furnace space, proper structure and layout. Small footprint, high operating efficiency, stable operating state, etc.

Therefore, once it is introduced into the market, it has won the love and recognition of the majority of users, and the proportion of its use in the market has been increasing year by year.

 

Many users are very interested in gas-fired steam boilers, but do not know the selection of boilers and market prices. Zhengzhou Fangkuai Boiler Factory will come to answer your questions. Take a 10-ton gas-fired steam boiler as an example.

At present, the market price of 10-ton gas-fired steam boilers in the market generally ranges between 80,000 and 120,000 US dollars. As for the high intermediate price, it is mainly because of the difference in boiler operating efficiency and quality. The boiler equipment with high operating efficiency is in use. It must be very energy-saving and money-saving, so when you buy a boiler, you should not only look at the purchase cost, but also take into account the later operating costs, so that the boiler can better serve us.

Zhengzhou Fangkuai Boiler Factory also reminds everyone of the importance of safety valves in gas-fired steam boiler equipment.

Safety valve is a safety device installed to prevent explosion caused by excessive pressure in equipment and container under abnormal conditions.

When the pressure in the equipment is too high, the safety valve automatically opens, and then automatically closes when the pressure drops to a safe range to prevent the equipment from exploding due to excessive pressure. Generally, the constant pressure of the safety valve is 0.5 to 1.10 times of the operating pressure.

According to its structure and principle of action, the safety valve is divided into gravity type, lever type, spring type and so on. The lever type is more suitable when the working temperature is high and the pressure is not too high; the spring type should be used for high-pressure equipment; generally, the spring type safety valve is commonly used.

How much does a 1 ton gas steam boiler cost?

Gas-fired steam boiler is one of the common equipment in industrial production and processing industries. The boiler uses natural gas as fuel. It is very convenient for transportation, installation and later use. It only needs to build water, electricity, and gas pipelines and it can be started and used normally. The boiler adopts low-nitrogen combustion technologies such as FGR and full premixing, and the pollutant emission can be as low as 30 mg/m3.

Many users are more concerned about the price of gas-fired steam boilers. Zhengzhou Fangkuai Boiler Factory takes a 1-ton gas-fired steam boiler as an example to provide answers for everyone. The current market price of a 1-ton gas-fired steam boiler ranges from US$10,000 to US$10,000, depending on the configuration of the boiler, but in general it is within this range.

Zhengzhou Fangkuai Boiler Factory also reminds everyone to pay attention to the use of blowdown expansion vessels on the boiler.

In the boiler equipment, the function of the blowdown expansion vessel is: when the boiler sewage is discharged into the expansion vessel, the volume expands, the pressure decreases, and the saturation temperature also decreases accordingly. Part of the waste water under the original pressure is released after the pressure is reduced. This part of the heat is absorbed by the water as the heat of vaporization and part of the sewage is vaporized. The vaporized part of the steam is introduced into the deaerator for recovery. This part of steam and heat.

The blowdown expander is also called blowdown expansion vessel, and its design and manufacture should be carried out according to GB150-98 of pressure vessel. The continuous blowdown expander is connected to the continuous blowdown port of the boiler. It is used to decompress and expand the continuous blowdown of the boiler. The blowdown is adiabatically expanded in the continuous blowdown expander and separated into secondary steam and waste hot water. After the internal expansion, pressure reduction, heat exchange, and then discharge, the secondary steam is led out by a special pipeline, and the waste hot water is automatically discharged through the float level valve or overflow regulating valve, and the heat energy can be recycled and reused. The continuous blowdown volume is automatically adjusted with the change of the boiler feed water load to maintain a relatively stable blowdown rate.

What are the ways to improve the thermal efficiency of industrial boilers?

Thermal efficiency data is very important for industrial boilers, which is directly related to the economic benefits of boiler users. It can be said that the design efficiency of the boiler determines the operating cost of the boiler. Generally speaking, the higher the thermal efficiency of the boiler, the greater the fuel consumption. Low, it will directly reduce the operating cost of the boiler.

At present, with regard to various furnace types such as oil-fired gas boilers and chain grate boilers, the average design thermal efficiency of domestic industrial boiler manufacturers is generally 70-90%, and the actual operating thermal efficiency is generally about 60-80%. Some small boiler manufacturers’ products Even below 50%. But in fact, there are ways to improve the thermal efficiency of industrial boilers. Let Zhengzhou Fangkuai Boiler Factory answer for you.

1. Increase effective use of heat, reduce boiler, exhaust heat loss and mechanical incomplete combustion loss.
       1) Reduce the air leakage rate of the air preheater, especially the air leakage rate of the rotary air preheater.
       2) Strictly control the water quality index of the boiler boiler water. When the scale content in the water wall tube reaches 400mg/m, it should be pickled in time.
       3) Try to burn fuels with high calorific value to reduce the air temperature at the inlet of the air preheater. Modern large-capacity power generation boilers are equipped with air preheaters to prevent condensation on the heating surface of the cold front end of the air preheater, leading to air preheating The device is corroded at low temperature.
       4) Adjust the combustion conditions according to the boiler load and time, reasonably distribute the air, and reduce the flame center position of the furnace as much as possible, so that the fuel can be fully burned in the furnace.
       5) To reduce the heat loss of the boiler, it is mainly to strengthen the maintenance and repair of the boiler pipe and the insulation layer of the body.

2. Scientific coal-burning ratio, rigorous process operation, improving air distribution, adding additives, etc.

Among industrial boilers, what are the differences and characteristics of vertical and horizontal bo

Vertical boilers and horizontal boilers are two types of industrial boilers, which are determined according to the internal structure design of the boiler. So, in industrial boilers, what are the differences and characteristics of vertical and horizontal boilers? Let Zhengzhou Fangkuai Boiler Factory answer for you.

Features of vertical boiler:
       The combustion part adopts a double-layer grate combustor, which heats up quickly and boosts pressure quickly. After secondary combustion of unburned gas, it has the functions of full combustion, smoke elimination and dust removal. The elbow pipe arranged on the upper part of the furnace body is the convective heating zone, and the grate tube and the furnace bladder arranged on the lower part of the furnace body are the radiation heating zone. The structure of the furnace body and flue gas flow are reasonable in layout and good heat transfer. The boiler has a reasonable design and simple structure. Easy to operate and maintain, small footprint, low capital investment, is one of the ultra-small steam and heating equipment.

Features of horizontal boiler:
       Large water capacity, high thermal efficiency, fast steam production, sufficient steam, long service life, equipped with high-quality brand-name burners and pressurized feed water pumps, full combustion, timely water supply, low noise; optional computer controller with self-diagnosis function, operation When abnormal, it will automatically shut down and give an audible and visual alarm to indicate the fault code, which is convenient for maintenance; the protection device is complete, and the burner can be equipped with a purge device after high temperature, which is safe and reliable. Equipped with multiple protection devices such as high-quality safety valve, pressure regulator, low water level and overheat protection to ensure the safe operation of the boiler; compact structure, small footprint, elegant shape, and bright color; small tubular 30-300kg/h vertical type Two-pass, 500-1000kg/h adopts vertical three-pass; high efficiency and energy saving: the furnace structure is optimized, and the heating area is large, especially the three-pass boiler has high thermal efficiency, fast gas production and long service life. Optional high-quality brand-name burner and pressurized feed water pump, full combustion, no pollution, timely water supply, low noise, is the best equipment for industrial gas or heating above 5000 square meters.

So, which vertical boiler or horizontal boiler has lower air consumption and lower investment cost? The technical engineers of Zhengzhou Fangkuai Boiler Factory also performed calculations and analyses for everyone.
       The gas consumption of the boiler is mainly determined by the efficiency of the boiler. In terms of cost, the choice of vertical boiler or horizontal boiler depends mainly on the installation site. Vertical boilers can be selected for small and small-scale applications, and horizontal boilers can be selected for spacious sites. In comparison, it mainly depends on the needs of customers, because the scope of use of these two boilers is different. For example, if you want to heat a 100,000 square meter community, then a vertical boiler is not acceptable. If you can’t bring a large heating boiler, you must choose a horizontal boiler. Industrial boiler.

What is the difference between a hot water boiler and a steam boiler, and where are they applicable?

Hot water boilers and steam boilers are relatively common boiler equipment in the market, and they have room for development in all walks of life. So, what is the difference between a hot water boiler and a steam boiler, and where are they applicable? Let Zhengzhou Fangkuai Boiler Factory answer for you.

Simply put, hot water boilers are used for heating and hot water supply, such as bathing centers, swimming pools, residential areas, etc. are all needed, and it can even be said that as long as it is a place that needs heating, hot water boilers are needed. The largest tonnage hot water boiler launched by the Zhengzhou Fangkuai boiler manufacturer is a 130-ton fuel-fired gas hot water boiler; while the steam boiler is mainly used in the chemical, building materials, textile and other industrial industries for the production of steam. Of course, it can also Heating is generally provided by the way in production workshops and industrial parks, which is the case of combined heat and power.

Hot water as a heat source is suitable for air conditioners, heaters, low-temperature ovens, drying equipment, hot water tanks for textile printing and dyeing, and various low-temperature heating, air-conditioning coils and heat exchange equipment. Hot water as a heat medium has the following advantages:
       1. Hot water boilers generally have a low heat medium temperature and a large temperature difference with the flue gas. The boiler exhaust gas temperature is relatively low, so the boiler efficiency is high;
       2. The closed hot water system has a small amount of make-up water, a much smaller blowdown rate than a steam boiler, and less water waste. In addition, the boiler water quality requirements are low, and the water treatment cost is low; 3. The specific heat capacity of water is large, the hot water capacity in the system is large, and the heat storage capacity is strong. When there is a short-term failure in thermal or hydraulic operating conditions, it will not cause significant fluctuations in heating conditions;
       4. The hot water heating system can be pumped for long-distance transportation, with small heat loss and large heating radius, which can meet the requirements of urban central heating planning. The main disadvantages of using hot water as a heating medium for heating are lower temperature, lower heat transfer coefficient, and lower heat utilization rate.

Relatively speaking, steam boilers are the most widely used in my country, because the industrial coverage is too wide. The main advantages of steam boilers are:
       1. Low cost and wide adaptability, which can simultaneously meet the heat requirements of a variety of users who have different requirements for pressure and temperature;
       2. Non-toxic, can directly heat food, etc., even if there is leakage, it will not cause harm to the environment;
       3. The steam temperature is relatively high, and the latent heat of vaporization is large. Compared with hot water, it can reduce the heat exchange area of ​​the equipment and reduce the cost;
       4. Low thermal inertia, heat up quickly when steam is supplied, and cool down quickly when steam is stopped. The steam heat medium is difficult to recover due to the condensed water, which causes a waste of latent heat and water resources. Even if there is a condensate recovery device, in the process of condensate recovery, the water easily dissolves impurities such as oxygen, which can easily cause harm to the boiler. Impurities such as oxygen and salt in the feed water will cause boiler fouling, corrosion and other problems, affecting the safety and energy saving of the boiler.

Which industrial sites are water tube boilers and fire tube boilers suitable for?

Water tube boilers and fire tube boilers are two types of boilers. Due to the differences in the internal structure of these two types of boilers, the applicable places and industries also have certain differences. For specific industries where water tube boilers and fire tube boilers are suitable, listen to the suggestions of Zhengzhou Fangkuai Boiler Factory.

Water tube and fire tube boiler are defined by the difference of the medium in the tube. The water tube boiler is the pipe passing water, and the water in the pipe is heated by the external flue gas convection/radiation heat exchange. The fire tube boiler is the pipe passing the flue gas, letting The flue gas heats the medium outside the tube to realize heat exchange. The fire tube boiler has a simple structure, large water and steam volume, good adaptability to load changes, and lower water quality requirements than water tube boilers. It is mostly used in the production process of small enterprises and domestic heating. . The heating surface of the water tube boiler is convenient to arrange, and the heat transfer performance is good. It can be used in the working condition of large capacity and high parameters in structure. But it has higher requirements for water quality and operation level. In order to help everyone understand, Zhengzhou Fangkuai Boiler Plant summarized the following points:
       (1) The pressure of water tube boiler has a wide range of adaptability, which can break through the pressure limit and meet the steam supply requirements of 2.5MPa or more. Fire tube boilers are limited by material wall thickness and pressure, and are used for pressures below 2.5MPa;
       (2) Fire tube boilers are shell-type boilers. Due to the limitations of the current equipment and tooling of various boiler manufacturers, it is more difficult to manufacture a fire tube boiler that is too large, usually below 35t/h. The water tube structure boiler can realize the large-scale boiler, and the boiler above 35t/h usually adopts the water tube structure; (3) The fire tube boiler has the characteristics of compact structure. Under the same output, the appearance and equipment weight are lower than the fire tube boiler. Due to the larger volume of the water tube boiler, there is more space for arranging the superheater, so the water tube boiler occupies a relatively large boiler room.

A way to ensure that the boiler you use can always operate safely and stably

Song Gong, a technical engineer at Zhengzhou Fangkuai Boiler Factory, said: No matter how good a boiler is, if you don’t know how to operate, maintain, and deal with emergency problems correctly, you cannot guarantee the safe operation of the boiler. The reason why the demands of workers are getting higher and higher.

Boiler is a kind of special equipment that is heated and pressurized. At present, as the performance and parameters of the boiler are improving, and the equipment structure is becoming more and more complicated, the safety management of boiler users is the prerequisite to ensure the safe and economic operation of the boiler. With the rapid development of boiler technology, our company's requirements for boiler operators must also be improved, and we should keep our eyes on the boiler when purchasing boilers. The quality of the boiler is the first guarantee, so as to ensure that the boiler can always be safe and stable. run.

In order to ensure the safe operation of boilers and prevent boiler accidents, according to the requirements of "Regulations for Periodic Inspection of Boilers", boilers should be inspected regularly. Periodic inspections include external inspections, internal inspections, and hydraulic tests. The boiler can be put into operation only when the internal inspection, external inspection and hydraulic test are all within the valid period.
       (1) Through the internal inspection of the boiler, it can be found whether the pressure-bearing parts of the boiler are cracks, grooves, overheating, deformation, leakage, corrosion, abrasion, scale and other defects that affect safety during operation.
       (2) Through the external inspection of the boiler, it can be found whether the operator has a certificate or works in violation of regulations, whether the boiler safety accessories are operating normally, whether the operation record is complete, whether the safety management personnel conduct regular inspections, etc.
       (3) Through the hydraulic test, it can be verified whether the strength and tightness of the boiler meet the original design requirements.

Zhengzhou Fangkuai Boiler Factory would like to remind you that if the safety management work of the boiler user unit is not in place, it is very prone to boiler operation with diseases, and safety accidents may occur at any time. In the past boiler accidents, it can be seen that, in addition to the quality defects of the boiler itself, most of the boiler accidents are mainly caused by the user’s failure to attach great importance to the basic policy of safe production, the lack of responsibility of the safety management personnel, and the operating personnel operating in violation of regulations, leaving their posts or failing to pay high attention to production safety. Caused by factors such as undocumented employment after training. Therefore, the boiler safety management is a systematic project, which is of great significance to the safety and economic operation of the boiler.

Compared with coal-fired boilers, what are the advantages of gas-fired boilers?

Coal-fired boilers have always occupied half of my country's boiler market and played an important role in my country's industrial production. However, with the emergence of environmental pollution, coal-fired boilers, as serious pollution equipment, have also received attention and treatment from environmental protection departments. Small and medium-sized coal-fired boilers have gradually withdrawn from the market in recent years. Gas boilers that integrate cleanliness, environmental protection, and high efficiency have been widely promoted and used. In recent years, the frequency of users' use has increased year by year. So, compared with coal-fired boilers, what are the advantages of gas-fired boilers? Let Zhengzhou Fangkuai Boiler Factory answer for you.

Why do so many people choose to use gas boilers? The specific reasons are as follows:
       1. The gas boiler burns completely, and the exhaust gas is pollution-free. The exhaust gas blackness of the gas boiler is 0 Ringelmann level, the SO2 content is very small, and the combustion efficiency can reach more than 99%;
       2. The gas boiler is easy to start and stop, and the temperature rises quickly. For the boiler that runs intermittently, the heat loss during the compression process can be omitted, which is beneficial to improve the thermal efficiency. Of course, due to the rapid temperature rise, the temperature of the furnace body changes drastically, which is detrimental to the life of the boiler.
       3. The fuel gas is completely burned, no fly ash, no particles scouring the furnace body like coal-fired boilers, and no ash on the heat transfer surface, which is good for heat transfer, and from this aspect, it is also good for prolonging the life of the furnace body.
       4. Gas fuel is transported by pipeline, and there is no ash and slag after combustion, which can save the coal storage yard and slag storage yard of coal-fired boilers. This is particularly important for large and medium-sized cities with little land; coal-fired boilers can be removed. The coal transportation system and slag removal system greatly reduce labor intensity and reduce urban transportation.
       5. The calorific value of the gas is stable, and the flow can be easily adjusted through the flow regulating valve, which is convenient to realize the automation of the production process, and the adjustment accuracy is high. It can be seen from the above five points that gas-fired boilers do have incomparable advantages over coal-fired boilers. Changing the fuel structure and vigorously developing the gas industry is an inevitable trend of social development.

Which boiler models are included in the shell boiler? What are the characteristics?

At present, shell boilers are used very frequently in various industries and markets, and they are deeply loved by users. So which boiler models are included in the shell boiler? What are the characteristics? Let Zhengzhou Fangkuai Boiler Factory answer for you.

The basic structure of the shell boiler is a double-jacket structure. The outer cylinder is called the boiler shell, and the inner cylinder is called the furnace (fire cylinder). The annular space between the inner and outer cylinders is filled with water, and the inner cylinder is the combustion chamber. When the water vapor medium is under pressure, the shell is under internal pressure, and the furnace bladder is under external pressure. Shell boilers are divided into two types: vertical and horizontal. At present, the commonly used oil and gas boilers are WNS type horizontal internal combustion shell boilers. Shell boiler has the following characteristics:
       1. Both the "pot" that holds water and the "furnace" that burns the fire are contained in a shell—the pot shell;
       2. The metal furnace (furnace) has a small volume, is surrounded by water, has a large degree of water cooling, and has poor combustion conditions. It is necessary to burn high-quality fuel;
       3. The heating surface is small, and the evaporation or heating power is small. Water pipes or pyrotechnic tubes are often installed to increase the heating surface and boiler capacity;
       4. The pot shell has a large diameter, many openings, and irregular shapes. The internal heated part and the unheated part are connected together, and the temperature and thermal expansion degree are different, so the safety of the shell is poor; 5. The boiler structure system is relatively simple, which is convenient for transportation, installation, operation management, inspection and maintenance.

The above are the characteristics of shell boilers summarized by Zhengzhou Fangkuai Boiler Factory. If you are interested in boilers or have technical requirements, you can directly call our online consultation hotline, and professional technical engineers will do it for you one to one. Answer questions.

Compared with other types of boilers, what are the advantages of quick-installed boilers?

According to the difference of boiler assembly methods, it can be divided into quick installation, bulk installation and assembled boilers. According to Zhengzhou Fangkuai Boiler Factory's investigation of the current boiler market, the production and use frequency of the quick-installed boiler is much higher than the other two types of boilers, which is inseparable from the advantages of the quick-installed boiler itself. Compared with other types of boilers, what are the advantages of quick-installed boilers? Let Zhengzhou Fangkuai Boiler Factory answer for you.

Quick-installed boiler means that the manufacturer basically completes the above installation work in its own unit. After inspection and acceptance, it is transported to the installation site, hoisted to the boiler foundation, and after inspection and acceptance, the pipes and other rotating machinery (blower, blower, Induced draft fan), and dust removal and environmental protection facilities, you can carry out trial operation. Generally, the production unit has the boiler body in stock, so the installation period is short. Products such as WNS quick-installed gas-fired boilers have relatively high efficiency and heat utilization, and have a small footprint, long service life, and low operating costs. They are generally small furnaces or prefer quick-installed boilers when they are urgently used.

Generally speaking, the boiler from the factory to the installation and acceptance of a boiler is like this: the manufacturer manufactures and processes according to the part drawing and assembly drawing of the boiler drawing, and after the quality inspection is carried out at the factory, it is transported to the boiler installation site for acceptance, and then according to Assemble the assembly drawing of the boiler (main installation: load-bearing frame structure of the boiler, upper and lower drums, water wall boiler tubes on both sides, economizer, superheater, safety device and other pressure components), and then carry out the main body pressure test of the boiler, and it is qualified Afterwards, the auxiliary equipment of the boiler (grate device, coal feeding device, slag removal device, etc.) will be assembled. After each device has passed the test run, the boiler's thermal insulation construction will be carried out, so that the main body of the boiler is basically installed.

In the heating field, is it more appropriate to use a hot water boiler or a steam boiler?

Heating is a major issue related to our people's livelihood. Generally, the heating range in northern my country is larger. Since heating is involved, it is inseparable from boiler equipment that provides heating for people. Many heating users have one reason when purchasing a boiler, that is, is it more appropriate to use a hot water boiler or a steam boiler? Regarding this question, let Zhengzhou Fangkuai Boiler Factory answer it for you.

Generally speaking, whether it is small-scale heating or large-scale central heating, hot water boilers are used. At present, the smallest tonnage industrial heating boiler provided by Fangkuai is 1 ton WNS hot water boiler, and the largest is 160 tons of SZS type water pipe hot water. boiler. Regardless of whether it is a large boiler or a small boiler, the pollutant emissions are much lower than the national limit, so that customers have no environmental concerns for decades. There is no need to worry about technology. The WNS series and SZS series hot water boilers launched by the Zhengzhou Fangkuai boiler manufacturer are well-deserved high-efficiency and energy-saving boiler products.

At present, there are few heating methods using steam as a heating boiler. If the heat source is steam, heat exchangers are often used as an intermediary, and the final user is hot water as the heat dissipation medium. If the factory will do this, while producing steam, it will separate the unnecessary steam to heat the office building or workshop. Let's take a look at the disadvantages of steam boiler heating:
       1. If the temperature rises too fast, the radiator will suddenly be hot and cold, and it will easily leak;
       2. If the pressure rises too fast, the radiator is likely to cause metal fatigue, reduce the life span, and easily cause the radiator to burst;
       3. The surface temperature of the radiator is too high, it is easy to burn people, and it also causes bad indoor weather conditions. Indoor dust decomposes above the radiator, causing the wall above the radiator to become black;
       4. If the heating effect of the heating pipe is not good before the steam is sent, it will cause water hammer when the steam is sent. The water in the radiator will form a water hammer under the impact of the steam, which will impact the radiator and pipes. Damage to radiators and pipes;
       5. The water in the boiler is heated to absorb the heat released by the fuel, and the water molecules become steam and have to absorb part of the heat, resulting in a waste of energy.

In summary, the use of steam boilers for heating is not economical and there are many hidden dangers. Therefore, in recent years, the use of steam boilers as heat sources has become less and less, and the use of hot water boilers for heating has increased year by year.
