Air consumption is an important indicator for evaluating the quality of gas-fired boilers. It is also one of the standards that users measure when purchasing boilers. This data will directly determine the cost of the company's investment in boiler operation.

FANGKUAI Boiler uses a 1 ton gas-fired steam boiler as the base to calculate the method for calculating the gas consumption of the boiler.

First of all, we need to identify the factors that affect the gas consumption of the boiler.
       1, the 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. On the one hand, the company saves more fuel.
       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 8600 kcal/m3, and the calorific value of diesel is 10240 kcal/kg. However, the cost of fuel should also be considered. comprehensive.
       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.
       The condensing gas steam boiler produced by Fangkuai uses a 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 supplied to the boiler for absorption again. The thermal efficiency can be It is as high as 108%. In one year, it can save the company the fuel input cost of 50,000 to tens of thousands (depending on boiler capacity and maintenance quality).
       4, the boiler output
       The output of a 1 ton boiler is 700,000 kcal, and so on. The output of a 10 ton boiler is 7 million kcal.

Formula for calculating fuel consumption
       Fuel consumption = boiler output ÷ fuel calorific value ÷ boiler thermal efficiency.

According to the above method, the user can calculate the gas consumption of the gas steam boiler according to the various values ​​provided by the boiler manufacturer, and more comprehensively understand the boiler and select the boiler equipment suitable for the enterprise.

Electric boilers are popular among users for their environmental protection, cleanliness, pollution-free, noise-free, and fully automatic functions. Then, how should electric boilers be used for maintenance work to ensure normal heating in winter? FANGKUAI Boiler summarizes the following contents for everyone to learn and reference.

First, the benefits of regular maintenance of electric boilers
       1. It can improve the efficiency of heat exchange of electric boilers and reduce the consumption of electricity. Through experimental comparison, the electric boilers that have been cleaned and maintained under the same conditions have a heating rate of about 25% faster than that of electric boilers that have not been cleaned and maintained. That is to say, the electric boiler can be cleaned after the original foundation. Save about 25% of the power resources.
       2. Extend the service life of the electric boiler. Descaling by internal cleaning can effectively reduce the load on the main components such as pumps and heat exchangers, thus making the boiler run more smoothly and prolonging its service life. If the boiler is cleaned and maintained once every two years, the service life of the equipment can be extended for 3-5 years.

Second, electric boiler maintenance methods
          First of all, we must ensure that the use environment of electric boilers should be in a dry, non-moisture environment. If the humidity is too large, it will easily lead to the occurrence of electricity in the electric boiler, causing electrical disasters.
       1. Before the maintenance of the electric boiler, we must first cut off the power supply, which can ensure the safety of subsequent operations.
         2. The electric boiler is mainly composed of a main body, an electric control box, a control system and various power supply cables. The maintenance and maintenance of these components should be controlled once every two months. For electric boiler burners, it is necessary to remove some foreign matter such as dust every two months during use; Wipe the test once a month; in addition, the filter inside the oil pump should be checked regularly. But be careful: do not damage the sealing pad to avoid damage to the oil pump.
       3. During the use of the electric boiler, the safety valve should be moved once a day to prevent rust from losing its original function.
       4. After all the inspection work is completed, all the tools and materials need to be put together, placed in the designated location, and then the safety record is prepared for later inquiry work.

The above is all the maintenance methods of electric boilers. Follow the steps to carry out the maintenance work of electric boilers to ensure a safe and warm winter.

The boiler price is the first consideration for every user when purchasing equipment, which makes the cost investment clearer and clearer. The same is true for natural gas boilers that have been commonly used in recent years. The price of natural gas boilers on the market is now different, and many users will have a feeling of fog when shopping. This is mainly due to regional factors, equipment materials, production processes and other reasons caused by different prices.

How much does it cost to buy a natural gas boiler? Xiaobian asked about the technicians who have many years of experience in boiler industry. He gave many factors that affect the price of the boiler. Let's take a look!

First, the manufacturing materials.
     Reasonable design structure, higher quality and more corrosion resistant configuration parts are the main factors that determine the quality and service life of the boiler. The internal parts of the gas boiler of FANGKUAI Boiler are collected from domestic and foreign high-quality brands, and both quality and post-maintenance services are guaranteed.
       Such as: Italian famous brand Liya Road burner, Grundfos pump, Siemens electric control, and so on.

Second, the service.
       Whether it is pre-sale, sale or after-sales service, it has a very important impact on the business.
      Professional and patient pre-sales consultation, good communication and cooperation between the two parties during the cooperation process, and daily maintenance and overhaul of the boiler operation will bring different experience to the users.
       FANGKUAI Boiler always believes in the business philosophy of “observing and thinking from the perspective of the user”. In the pre-sales consultation, sales cooperation and after-sales remote monitoring system, 120% of the energy is invested to provide users with high quality boiler products. diligent.

Third, the brand.
       I have to say that the influence of the brand is endless. To build a good reputation, to become a boiler brand in the hearts of users, is the soft power of a boiler enterprise. The good word-of-mouth is the most authentic feedback that countless users have after using the boiler. It also depends on the boiler's own quality.

After reading this article, I believe that everyone has some control over the price of natural gas boilers. If you have not yet determined what type of natural gas boilers to buy, you can directly consult the customer service on this site to find out the differences between the different brands of equipment. We will connect with professional technicians to help you select a natural gas boiler that is more suitable for your business.

Many users face the problem of installing boilers after purchasing gas boiler products that suit their needs. Based on the experience of FANGKUAI Boiler technicians installing boilers on the customer site for many years, the following sections summarize the following precautions for gas boiler installation, hoping to help your boiler installation more smoothly.

First, prepare for the installation.
       1. Determine the installation location of the boiler. The unit that installs the boiler must hold the boiler installation certificate issued by the higher authorities in accordance with the installation requirements.
       2. To go through the registration procedures, according to the “Steam Boiler Safety Supervision Regulations”, the units that use the boilers need to go through the registration procedures for each boiler. The boiler user needs to have a person responsible for the work, and is responsible for communicating with the local pot inspection station and docking all installation procedures.
       3. Inspect the boiler and accessories, carry out comprehensive inspection and acceptance of the boiler body, combustion equipment, auxiliary machine parts, etc., and make a record. If it is found that the parts that do not meet the standard are promptly reported to the boiler manufacturer.

Second, the installation work.
       1. Boiler body, auxiliary machine, accessory packing box, instrument packing box, etc. need to be hoisted according to the specified position, and the position cannot be changed at will.
       2. There should be enough space around the installation location to facilitate simple maintenance work at the later stage. The boiler door and each inspection hole must be opened.
       3, in the boiler room, you need to leave the air inlet, and also equipped with filters and other equipment, and timely cleaning to prevent blockage.
       4. Do not place flammable and flammable materials, corrosive gases and volatile substances in the boiler room.

Third, the inspection after the completion of the installation.
       1. After the boiler is installed on the ground, it is necessary to carry out comprehensive inspection and maintenance work to ensure that the boiler will not leak when it is put into operation later.

As a square-speed boiler focused on clean fuel boilers for 20 years, FANGKUAI Boiler has considerable industry experience in gas boiler installation and has a very professional user field installation engineer to provide you with services that meet your needs.

Recently, FANGKUAI Boiler's pre-sales customer service staff gave us feedback, and received many consultations from users who opened the bathhouse. For the bathhouse, you can use the gas condensing boiler and choose how big the boiler is. In fact, the use of gas condensing boilers is completely ok, and there are quite a few advantages compared to coal-fired boilers.

So what are the benefits of using a condensing gas boiler?

One or eight low
       1, low energy consumption
       2, low noise
       3, low exhaust gas temperature
       4, low temperature combustion
       5, the required natural gas pressure is low
       6, the required voltage is low
       7, low water pressure
       8, Low NOx emissions

Second, three high
       1, high thermal efficiency
       2, high degree of intelligence
       3, high safety performance index

Three or three small
       1, small footprint
       2, light weight
       3, less labor demand

The condensing gas boiler produced by Fangkuai boiler adopts low-nitrogen combustion technology such as full premixing and FGR. The thermal efficiency can reach about 108%, and the natural gas is fully burned. It also has multiple intelligent interlocking control, accurate and complete self-test, and the user uses Peace of mind, peace of mind, peace of mind!

We will provide you with detailed scheme design, including actual operation cost and overall system cost, and send special personnel to conduct on-site inspection, design and installation location, and meet your needs within the feasibility limit.

Many users will be confused by a number when they understand the FANGKUAI Boiler. Why is the thermal efficiency of the boiler produced by the fast-growing boiler reaching 108%?

The input of the condensing gas boiler is a certain volume of gas multiplied by the calorific value of the gas (the influence of the temperature, pressure and humidity of the air should be taken into account when calculating the heat), and the difference of the condition factors determines the calorific value of the gas has a high calorific value and a low calorific value. Points.

High calorific value: 1 standard cubic meter of gas is completely cooled after the flue gas is cooled to the original temperature, and the water vapor in the flue gas is discharged in the state of condensed water.

Low calorific value: 1 standard cubic meter of gas is completely cooled after the flue gas is cooled to the original temperature, but the water vapor in the flue gas is still the heat released by the steam state.

Obviously, the high calorific value of the gas is numerically greater than its low calorific value, and the difference is the latent heat of vaporization of the water vapor. The actual low-heat value of gas is commonly used in the actual engineering of industrial and civil gas applications. If calculated according to the low calorific value, the condensing gas boiler can absorb the latent heat of vaporization, and its thermal efficiency may reach 108%.

Then, why is the calorific value of the gas calculated according to the low calorific value not calculated according to the high calorific value?

This is because, in fact, the calculation of the calorific value of the gas by the operating instrument is to detect the volume and temperature of the flue gas generated by the complete combustion of the gas, and it is difficult to completely collect and cool the flue gas to the original temperature according to the definition of high and low calorific value of the gas. of. It can only be high-temperature discharge, measure the flue gas flow, calculate its volume and measure the temperature of the flue gas, calculate the heat through the heat capacity ratio of the flue gas; while the water vapor in the high-temperature flue gas is not cooled, it is still in the steam state. . This is consistent with the definition of low calorific value of gas, which is still a requirement for steam. Therefore, the calorific value of the gas in the thermal efficiency of the gas boiler is calculated based on the low calorific value. Then the gas condensing boiler absorbs the latent heat of vaporization, and its thermal efficiency will reach 108%.

The market researchers of Fangkuang boiler found that many users were confused when they purchased the boiler, and they were confused about the gas boiler with the "commercial condensation" label. I don't understand how it differs from the conventional gas boiler. Zhengzhou Fangxue Xiaobian will find out with you!

The difference between the two:

First, the applicable places are different
       A, commercial condensing gas boiler
       The commercial condensing gas boiler produced by Fangfang has been added to the Ultrate heat exchange component, the wing tube, which is designed and developed by itself. The heat exchange efficiency is more than 5 times that of the ordinary heat exchange tube. The heat exchange environment of the same heat exchange environment is designed to be shorter and larger. To save the boiler's floor space, it can save more than 40% compared with conventional gas boilers. It is suitable for hotels with small construction areas such as hotels, shopping malls and schools.
       B, conventional gas boiler
       Conventional gas boilers on the market basically use traditional fittings and systems, which are characterized by large weight, large volume, and non-removable, limited by the position and size of the boiler room.

Second, thermal efficiency
       A, commercial condensing gas boiler
       The heat exchange efficiency can reach 103% to 108%, which can be increased by about 30% compared with the conventional gas boiler. The boiler also incorporates international advanced combustion technology such as full premixing and FGR. When natural gas fuel is fully burned, the demand for air is reduced, there is no excess air, and the leakage point of the flue gas is increased, so that the flue gas enters the condensation stage as soon as possible to further Improve the combustion efficiency, the boiler heat exchange area is large, the thermal efficiency is high, the exhaust gas temperature can be as low as 50 ° C, and the heat loss is reduced.
       B, conventional gas boiler
       Some manufacturers generally indicate that the boiler design thermal efficiency is 90% in the brochure, but the actual thermal efficiency may only reach 70%~85%; the exhaust temperature is also in the range of 150~220 °C; the temperature control range is rough, and the precise temperature supply cannot be achieved. There is a problem of excessive consumption of energy by excessive heating; and the non-condensing heat exchange device has a high exhaust gas temperature and a high heat dissipation temperature of the furnace body, so the running cost is relatively high.

Third, safety and reliability and environmental impact
       A, commercial condensing gas boiler
       In today's society, intelligence is becoming more and more popular, and boilers must keep up with the direction of the times. The commercial condensing gas boiler produced by Fangfang can adopt the high intelligent PLC control system to complete the boiler startup, regulation and shutdown modes through simple operation of the operation interface.
       The boiler also has a number of safety protection measures. Pressure, temperature, scale, power supply, burner and other parts are equipped with monitoring and early warning probes. Once the fire of the safety accident is discovered, the early warning device can be quickly activated.
       The boiler is also equipped with insulation and mute components. The working noise is less than 60 decibels (normal speaking sound), and there is almost no environmental noise pollution. Therefore, the boiler can be placed in the living quarter without affecting the normal life of the residents and there is no disturbance. phenomenon.
       B, conventional gas boiler
       The various safety and security measures mentioned above require a lot of cost for R&D and manufacturing. Many boiler manufacturers will reduce some safety warning probes to save costs, which is a hidden danger for users.

Some boilers provide burners that use cheaper blast-type burners, which are more noisy and can affect the normal lives of nearby residents.

People's living standards are constantly improving, and the pursuit of heat in life is more efficient, energy-saving, comfortable and convenient, and low-environmental environmental protection. This trend has prompted the boiler industry to move toward a clean and low-nitrogen environment, and the corresponding low-nitrogen condensing gas boilers have also been introduced. Towards a more intelligent and diversified direction. So, what are the advantages of low-nitrogen gas boilers, why are they so praised by users?

The word “nitrogen” in “low nitrogen” refers to a series of polluting gases such as nitrogen oxides that have a bad influence on the atmospheric environment. A large amount of emissions into the air can cause bad weather such as acid rain and haze, giving people a life and Physical health poses a threat.

The emission of nitrogen oxides from ordinary gas-fired boilers can reach 150-200 mg/m3. In recent years, it has been gradually banned from burning or low-nitrogen reformation by China's environmental protection department. The low-nitrogen gas boilers significantly reduce nitrogen oxide emissions by using advanced low-nitrogen combustion technologies such as full premixing and FGR flue gas recycling. Fangxuan Boiler has introduced a low-nitrogen condensing gas boiler of less than 20 mg/m3, which is suitable for the most stringent environmental protection standards in China such as Beijing, Xi'an and Zhengzhou (standard 30 mg/m3).

What are the advantages of using a low nitrogen condensing gas boiler?
       1. Capacity expansion is good
       With seasonal changes or other circumstances, the user's demand for boiler heat output has also changed. The fast low-nitrogen condensing gas boiler can adopt multiple joint control modes, and the number of operating units can be flexibly adjusted according to different needs of users. User needs, and avoid unnecessary waste.
       2. Small footprint
       After thousands of tests, the boilers have been properly selected. Compared with ordinary gas-fired boilers, the boilers can save more than 20% of the floor space, lower the boiler building infrastructure requirements, and reduce the user input costs.
       3. Running quiet
       Fang quickly chooses the internationally renowned brand, Liya Road burner, which has good sound insulation effect and significantly reduces the noise generated by combustion and flue. The noise is less than 60 decibels (normal speaking sound).
       4. A wide range of applications
       Due to the modular design structure of the boiler, the installation and transportation are very flexible, and the emission of harmful substances is very low. It is widely used in large-scale use places such as hotels, office buildings, hospitals, shopping malls, schools, factories, etc.
       5. Energy saving and environmental protection
       The boiler is equipped with a natural gas combination proportional control valve and a full premixed fan, which not only ensures an excellent air-fuel ratio, but also automatically adjusts the boiler output to meet the dynamic heat load, so that the boiler heat output curve is as close as possible to the dynamic heat demand curve, Produce invalid output, heat exchange efficiency can reach 108%, realizing energy saving and environmental protection.

Some indoor swimming pools are still open during the cold winter season, mainly due to the indoor use of hot water boilers to heat and heat the water in the swimming pool.

In recent years, with the country's vigorous promotion of the "coal to gas" project, the northern regions of China have begun to use gas-fired hot water boilers to provide heating and hot water to residential areas, hotels, hospitals, shopping malls and some entertainment venues.

For some places with large area of ​​use, the gas-fired boilers with smaller capacity can not meet the heating demand; therefore, according to the needs of users, the gas boilers with different capacities can be designed with a new design concept, environmentally-friendly and efficient image. The boiler market has been widely recognized and highly evaluated by many customers.

Measuring the quality of a boiler is determined by a variety of factors. Comprehensive judgments such as thermal efficiency, input cost, use effect, environmental protection index, and post-maintenance can make the most comprehensive choice possible.

The gas-fired hot water boiler produced by Fangfang has achieved excellent results in the field of clean boilers with outstanding advantages such as high efficiency, durability, safety and reliability, and simple operation. It has won the favor and recognition of a large number of customers.

Nowadays, there are many brands of gas boilers on the market. Which brand is better?

FANGKUAI Boiler as a professional manufacturer of clean gas boilers, it not only has condensing gas boilers, commercial gas boilers, but also full premixed condensing gas boilers, which can provide suitable products for different needs of consumers.

Winter is approaching, heating is also put on the agenda by various heating units, and major boiler companies are competing to launch a variety of heating boilers, electric heating boilers are one of them. So, what are the key points to pay attention to when choosing an electric heating boiler?

First, choose the brand.
       When major boiler manufacturers sell their products, they always list all kinds of advantages and promises to the after-sales service, but they can do exactly what they promise. Therefore, when choosing a boiler, we must also consider the brand of the boiler manufacturer. Try to choose a boiler manufacturer with excellent product quality and good after-sales service to ensure your rights and interests.

Second, select power.
       When the electric boiler is used for heating, it needs to select the appropriate power according to the heating demand. If the power is too large, it will waste money, and the power is too small to meet the user's requirements. Generally speaking, the outlet temperature of electric boilers used for heating is above 70 °C. After 30 minutes, the temperature of the radiators of each household can reach about 75 °C; the heating area of ​​one cubic meter needs about 35W of heat, you can combine your own The required heating area is calculated to obtain the specific electric boiler power.

Third, choose technology.
       A good electric boiler should have high thermal power and fuel utilization, and it has a good experience in terms of insulation effect, safety protection, operating system and so on.
       The electric boiler body produced by FANGKUAI adopts reliable hydropower separation design, which has better safety. At the same time, it has multiple protection measures such as multiple water level, water temperature, secondary overheating, over temperature, leakage, antifreeze and power supply abnormality, among which antifreeze protection It is a unique patent technology that guarantees the safe operation of electric boilers.
       An inspection hole is arranged on the top of the boiler body, and a hand hole is arranged at the bottom for convenient inspection and maintenance.
       The boiler also has a variety of automatic control functions, which can be operated through the boiler's own operation interface to reduce manual consumption.
       The thermal insulation material is made of high-grade centrifugal glass wool for multi-layer insulation, the thermal insulation effect is good, and the thermal efficiency is naturally improved.

If you need electric boiler for heating project, please feel free to contact us through the free hotline of 0371-55629010. The professional technicians of FANGKUAI Boiler will be happy to provide you with services.

I believe that every user is full of doubts about the boiler when they first purchase the boiler. The choice of boiler model is undoubtedly one of the most important and difficult issues. If you choose a larger model, it will result in wast FANGKUAI Boiler makes a simple calculation formula. You can estimate the boiler capacity to be used according to your actual situation. Boiler capacity calculation formula: boiler model = actual height of the plant ÷ international height (2.8m) * building area When selecting the boiler model, the user's building area, the average height of each floor frame, the number of radiators, whether it is geothermal (if it is geothermal, the area can be doubled, and the area can be selected when it is large. two).

For example: there is a factory area of ​​10,000 square meters, the plant height is 5 meters, the boiler model is estimated: 5 ÷ 2.8 * 10000 = 17857 square meters, according to a ton boiler can meet 5500-6000 square meters to calculate, you need to choose 4 Steamed tons of boilers. And according to the temperature of different regions of the country, the area provided by each type of boiler will also change relatively. The colder north area, the heating area of ​​1 ton boiler will be reduced.

“Environmental Boiler” is a relatively general concept. In a broad sense, it refers to the emission of emissions such as waste gas and waste, and it is a boiler that does not only refer to a certain type of boiler.

According to China's latest air pollutant emission standards in some areas, the minimum emission standards for nitrogen oxides in Beijing, Zhengzhou and Xi'an have dropped to 30 mg/m³.

For fuel gas boilers, it is an “environmental boiler” by using advanced combustion technology or an environmentally friendly burner to achieve nitrogen oxide emissions of less than 30 mg/m³.

Electric boilers need not be elaborated. Because of the use of electricity as a power source, there is no emission of waste gas, which is even more of an "environmental boiler" type.

Most of the environmentally friendly boilers use FGR, full premixing and other advanced combustion technologies to reprocess the flue gas, reuse the flue gas waste heat, and reduce the flue gas temperature. It can not only improve the thermal efficiency of the boiler, but also reduce the emission of harmful substances in the flue gas, and realize the social and economic benefits of environmental protection and energy conservation.

FANGKUAI Boiler has many years of experience in clean boiler manufacturing and sales, and has a number of patented R&D technologies. The boilers produced meet the most stringent air pollution emission standards in China.
