An electric steam boiler is a device that converts electrical energy into heat energy by electric heating, thereby causing the boiler to complete the reaction and output steam to the outside.

So, what are the precautions for users when purchasing electric steam boilers for the first time? Fang fast boiler for your science.

First, thermal efficiency
       The thermal efficiency is related to the operating cost of the electric steam boiler. The thermal efficiency of the electric steam boiler developed by FANGKUAI can reach more than 98%, which is about 20% higher than the thermal efficiency of the ordinary electric steam boiler on the market, so it is more energy-saving and economical.

Second, the steam time
       The steam outlet time refers to the time taken from the start-up of the machine to the generation of steam that meets the temperature requirements. The shorter the time, the more energy-saving. The steaming time of a typical steam boiler is about 30 minutes. The electric steam boiler produced by FANGKUAI boiler only takes 30 seconds to produce steam, which saves the company a lot of operating costs.

Third, energy saving and environmental protection
       Many central cities in China implement air pollutant emission standards of 30 mg/m3, which is a challenge for many boilers. The electric steam boiler has no combustion chamber and no chimney, and does not need to consider the heat loss problem. At the same time, it has the characteristics of clean and pollution-free, and is more energy-saving and environmentally friendly.

Fourth, safety performance
       The safe and stable operation of the equipment is undoubtedly a magic weapon that makes the enterprise more secure and more worry-free. The square electric steam boiler can adopt modular installation structure, and the customer can flexibly adjust the use of single or multiple devices according to the actual steam consumption, ready to use, simple maintenance and space saving. In addition, the boiler also adopts the PLC intelligent control system designed and developed by FANGKUAI, which is fully automatic and runs without special personnel, saving labor costs.

Of course, there are still many problems to be aware of when purchasing an electric steam boiler. The above aspects are among the more important factors. Combining the above factors, we can judge the quality of the electric steam boiler and help you purchase it for your own business. The boiler used.

Good maintenance can improve the efficiency of heat exchange in electric boilers and reduce electricity consumption. 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.

At the same time, it can extend the service life of electric boilers. 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.

Electric boiler maintenance method
       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.

First, before the maintenance of the electric boiler, we must first cut off the power supply, so as to ensure the safety of subsequent operations.

Second, the electric boiler is mainly composed of the body, the electric control box, the 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.

Thitd, during the use of the electric boiler, the safety valve should be moved once a day to prevent rust from losing its original function.

Forth, after all inspections are completed, all tools and materials need to be placed, placed in the designated location, and then safely recorded for later enquiry.

The boiler price is the first consideration for every user when purchasing equipment, which makes the cost investment clearer and clearer. 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.

What is the best way to buy a good gas boiler?

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.

First of all, the boiler manufacturer should be assessed.
       In general, users will have higher quality requirements for commercial boilers.

Second, the boiler must be selected.
       1. Boiler combustion efficiency
       Commercial gas hot water boilers are mainly used for heating and bathing, so it is necessary to provide all-weather, uninterrupted water supply and heat supply. When purchasing, you should first understand the thermal efficiency of the boiler. Attention should be paid to the boiler exhaust temperature, excess air ratio, fuel combustion utilization rate, furnace wall heat dissipation strength, etc. (see the next article for specific factors affecting boiler thermal efficiency). The boiler combustion efficiency directly determines the cost of boiler use.
       2. Boiler circulating water pump
       Among the components operating in gas-fired hot water boilers, circulating water pumps are one of the most vulnerable parts. Boilers with good high temperature resistance, low noise and low vibration should be selected, and the service life of such boilers will be greatly enhanced.
       3. The boiler protection device
       A good boiler not only has high thermal efficiency and resistance to the use of components, but also a protective device. When there are many unexpected situations such as low temperature, high temperature, high water level and low water level, the boiler should have very sensitive and obvious alarm devices to ensure the safety of the boiler.
       4. The boiler anti-seize device
       Considering the special nature of commercial gas hot water boilers, it is necessary to pay attention to whether the boiler has anti-seize devices. This device is related to the service life of the boiler and also relates to the stability of the equipment and cannot be ignored.

Finally, boiler after-sales service is also an important assessment point for users when selecting boiler products.
        A well-established boiler manufacturing brand, even if it is a little expensive, will also feel unlimited safety during use.

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.

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 FANGKUAI Boiler has achieved excellent results in the field of clean boilers with outstanding advantages such as high efficiency, durability, safety and reliability, and simple operation, and 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?

As a professional manufacturer of clean gas boilers, FANGKUAI Boiler 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.

Many users face the problem of installing boilers after purchasing gas boiler products that suit their needs. The technicians of FANGKUAI Boiler have summarized the following precautions for the installation of gas boilers based on years of experience in installing boilers on the customer site.

First, the preparation work before 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 work after 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.

When enterprises purchase heating boilers, many indicators such as heating area, building height, and insulation measures are the criteria for determining the type of boiler to be purchased.

As far as the heating area is concerned, FANGKUAI Boiler's existing boiler equipment can reach a heating area of 10,000 square meters for a 1 ton hot water boiler. If it is for large centralized residential areas or heating companies, when the heating area is too large, we will recommend a gas water pipe hot water boiler for you.

Due to its unique structure, the water tube boiler is less affected by capacity and pressure, and can be customized according to user needs. Recently, we have provided a 80-tonne and a 40-ton water-pipe hot water boiler for Gu'an Huaxia Happiness Real Estate Company for heating in residential areas.

Of course, the specific situation needs to be analyzed in detail. We also have a variety of boiler products for small heating areas, such as commercial, condensation series.

The boiler is a device that consumes a lot of energy, and the energy-saving device of the gas boiler is born based on this. In order to save energy, the waste heat of the high-temperature flue gas discharged from the boiler is reused. The manufacturer installs the economizer near the tail of the boiler or near the top flue, which is a component for heating the water supply. The gas boiler installed with the economizer can improve the efficiency of the boiler by lowering the exhaust gas temperature, thereby achieving the purpose of saving fuel.

Classification of energy savers:
       Depending on the application and the exchange medium, the energy saver is mainly divided into flue gas-liquid boiler economizer, flue gas-air boiler economizer and all stainless steel 304 frame plus stainless steel spiral finned tube (high frequency welded pipe), which has fast heat transfer. , energy saving, durable and so on.
       The energy-saving device produced by FANGKUAI Boiler uses a spiral finned tube structure with high heat exchange, which increases the heat exchange area by 5 times compared with the ordinary light pipe heat exchange, and the heat exchange rate is directly increased by about 5 times. It not only meets the energy-saving requirements of boiler operation, but also saves a lot of use area.

Generally speaking, the price of the energy-saving device of the gas boiler is related to various factors such as the volume of the boiler body and the expected effect. If you want to know the specific price of the energy-saving device, you need to communicate with professional technicians according to your own needs.

In the boiler market, a boiler product called “condensing” boiler is getting windy. So what are the advantages of this kind of condensing boiler? What are the advantages compared with ordinary boilers?

First, as the name suggests, the condensing boiler is a boiler that uses condensation technology. The flue gas discharged from the boiler is re-heated by the condensing device, and the sensible heat and steam condensation in the exhaust gas are fully utilized to form the latent heat released by the water droplets. The purpose of boiler thermal efficiency.
       After the traditional boiler is used, the exhaust gas temperature is generally around 160~250 °C, and the water vapor in the flue gas is still overheated, and there is a large amount of unused heat. Generally speaking, the thermal efficiency of the boiler is calculated according to the low calorific value of the fuel. The heat of the latent heat of vaporization in the high calorific value of the fuel is not calculated, so the thermal efficiency of the conventional boiler can only reach about 87%~91%. The condensing boiler added with the condensing technology also recycles the heat of vaporizing latent heat in the flue gas discharged from the fuel, and reduces the exhaust gas temperature to 50-70 ° C, and the boiler thermal efficiency is also improved. If the efficiency of an ordinary boiler is generally around 93%, and the condensing furnace technology can increase it by 15%, it can reach about 108%. Such an energy-saving and environmentally friendly boiler will inevitably lead the development trend of the future boiler industry.
       Taking natural gas fuel as an example, its high calorific value is about 9500kcal/m3, and the low calorific value is about 8600kcal/m3, which is about 900kcal/m3, which accounts for 11% of the low calorific value. Therefore, the choice of condensing boiler will be compared with ordinary boiler. Reduce gas operating costs by about 11%. (See details for high and low calorific value)

Second, the condensing boiler is more environmentally friendly. Compared with traditional coal-fired boilers, condensing boilers generally use clean and environmentally friendly natural gas as fuel. The exhaust gas generated by boiler operation is greatly reduced, and the emission of harmful substances such as sulfur oxides, nitrogen oxides and dust in urban air is alleviated. Environmentally friendly pioneer boiler products.

FANGKUAI Boiler has many years of experience in research and design of condensing boilers. The condensing series boilers have thermal efficiencies of over 107% and nitrogen oxide emissions of less than 30 mg/m3. They are also safe to use and have a long service life. The operation has many advantages such as low heat loss and has been widely used and used by users after being put into the market.

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 Boiler 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.

For many users who want to open a bath, it is a headache to estimate how much boiler is needed based on the number of nozzles and the amount of water used. Below, we will take 100 nozzles and an average bath temperature of 40-60 °C as an example to answer your need for boiler equipment.

When calculating the boiler capacity, it is necessary to use 100 nozzles (the highest value) at the same time as the standard, and temporarily ignore how many people use at the same time, but use the number of nozzles as the estimation unit, as long as 100 nozzles are used at the same time.

An adult bathing water is about 0.2-0.3 tons per hour, and 100 nozzles use 20-30 tons per hour. Therefore, it is only necessary to satisfy a boiler that can supply hot water between 20-30 tons per hour. Considering the various factors such as the difference in bath water temperature, we estimate that 100 bathing nozzles will require a 2 ton bath boiler. If it is necessary to carry out the heating of the bath, it is necessary to calculate according to the actual heating area. You can tell our online customer service about your heating area and bathing nozzles, and the technician will give you a detailed analysis later.

At the same time, in addition to the boiler tonnage problem, there is a need to choose fuel. It is best to use fuel or gas boilers in the baths in towns. These two types of boilers are not only environmentally friendly but also well managed, and do not require special space for fuel storage. Also pay attention to the choice of water tank. Generally speaking, the boiler and water tank should select the maximum value, which can not only meet the needs, but also effectively avoid the boiler overload operation and prolong the service life of the equipment.
