What models of atmospheric hot water boilers are available on the market?

Atmospheric hot water boilers are often used in the field of heating and heating, because the boiler does not carry pressure, it is safer to use, and it is very safe to use in places with a large flow of people. At present, the atmospheric pressure hot water boilers on the market are mainly classified according to the fuel used. The most frequently used ones are gas-fired atmospheric pressure hot water boilers, oil-fired atmospheric pressure hot water boilers and electric heating atmospheric hot water boilers, which are clean The advantages of environmental protection, high thermal efficiency, safety and stability. Zhengzhou Fangkuai boiler manufacturer will focus on the above three types of atmospheric hot water boilers, and tell everyone what are the characteristics of these boilers and which places are suitable for.

Gas-fired atmospheric hot water boilers refer to boilers that use natural gas, coal gas, biogas, and liquefied petroleum gas, among which natural gas is used more. Therefore, the gas-fired atmospheric hot water boilers we usually refer to mostly refer to natural gas. Pressure hot water boiler. Because the fuel used is clean energy, it has the characteristics of environmental protection, low pollution, meets air pollution standards, is conducive to environmental optimization, and has a high degree of intelligence, which is simple and quick to operate.

Oil-fired atmospheric hot water boiler refers to boiler products that burn into light oil and heavy oil. It can be said to be a substitute for gas boilers. In some areas, gas boilers need to be opened with natural gas pipelines, but in remote areas without natural gas pipelines, they cannot be used. Therefore, we only need to use an oil storage tank to use hot water boilers. It is a type of boiler product with higher comprehensive performance.

The fuel used by the electric heating normal pressure hot water boiler is electric energy, and there will be no exhaust emissions, so it is a very environmentally friendly and clean boiler. Electric boilers have advantages in terms of performance, operation and safety, but there is a disadvantage that their operating costs are higher.

What are the maintenance methods for oil and gas boilers?

Oil and gas boilers are dual-purpose boilers for oil and gas. They can use oil fuels and gas fuels. They have a wide range of applications and are therefore favored by more and more users. But everyone can't ignore the regular maintenance of oil and gas boilers, which can effectively extend the service life of the boiler and reduce losses. Zhengzhou Fangkuai Boiler Factory summarized the following maintenance methods for oil and gas boilers, hoping to help everyone better operate the boiler equipment.

First of all, it is necessary to check the body of the oil and gas boiler, focusing on whether the boiler body has water leakage, boiler fouling, flue carbon deposits, boiler leaks and flue chimneys are unobstructed, and if problems are found, corresponding repairs should be taken in time .

Secondly, the oil and gas boiler should be descaled regularly, and the following methods can be selected:
       1. When the boiler is shut down for a short time, it is more convenient to use wet maintenance. First, drain the water in the hot water boiler, remove the scale and dirt in the boiler, close all the valves and holes of the boiler, pour softened water into the boiler, and dissolve the prepared sodium hydroxide or trisodium phosphate into the boiler; Then heat the boiler water to 100°C under a low fire, and let the gas out of the furnace. When the boiler water emerges from the air valve, close the air valve, water supply valve, furnace door and baffle to seal the boiler. The general method of alkaline solution preparation is to add 5-8kg sodium hydroxide or 10-12kg trisodium phosphate per ton of water.
       2. When the boiler has been shut down for a long time, dry maintenance is more appropriate. First, drain the water in the boiler, remove the scale and dirt in the boiler, pour softened water into the boiler, increase the pressure of the boiler to 0.1MPa with a slight fire, and then stop burning; when the furnace temperature and pressure decrease, turn on the blowdown again The valve drains the boiler water and uses the waste heat of the boiler to dry the boiler; then puts a desiccant in the furnace, closes all valves and orifices, and seals the boiler. The desiccant generally uses quicklime or silica gel. The amount of quicklime is 2 to 3 kg per cubic meter of volume and 1 to 3 kg of silica gel per cubic meter of volume. The desiccant should be placed in an open container and placed evenly; afterwards, check it every 1 to 2 months. After the silica gel expires, it can be dried and reused.
       3. Maintain the valves, pressure gauges, thermometers and automatic exhaust valves on the hot water pipe network. Check the anti-corrosion layer and heat preservation of the pipeline surface, the indication of the pressure gauge and thermometer, the single flow valve, the stop valve, the automatic exhaust valve and the manual exhaust valve at the end, and repair and replace in time if any problems are found.
       4. Clean the hot water pipe network of the boiler to prevent corrosion. Discharge the hot water pipe network, check the water quality, replace the softened water, etc., take the wet maintenance of the whole hot water pipe network, and then close all the valves after filling it with softened water.
       5. Maintenance of the burner of the oil and gas boiler is mainly to clean the internal carbon deposits of the burner, clean the burner nozzle, clean the fan, clean the control device, etc. and seal the burner with a plastic bag.
       6. Maintain the circulating pumps and feed water pumps of the oil and gas boilers, check, repair and replace bearings, water seals, noise, wiring, etc.; add lubricating oil to the manual disc pump at the same time to clean up the grease and dust on the surface of the water pump, and cover it with plastic.
       7. Maintain the water softener equipment, whether the water softener is operating normally, whether the salt tank and hoses are leaking, whether the resin is effective, etc., if any problems are found, repair it immediately; remove the power plug of the water softener after repairing, and discard the salt tank In the brine, seal the connecting pipe between the water softener and the salt tank with tape.

The above is the summary of Zhengzhou Fangkuai Boiler Factory for everyone. Regarding the maintenance methods of oil and gas boilers, I hope to help you better operate and run the boiler.

What are the more common combustion methods for boiler equipment?

The combustion method of the boiler equipment is also a factor that the majority of users will consider when selecting the boiler. Depending on the combustion method, the boiler structure and boiler room layout will be different. Today, Zhengzhou Fangkuai boiler manufacturer will briefly introduce to you, what are the more common combustion methods of boiler equipment at present.

1. Diffusion combustion
       Advantages: This kind of combustion method is to mutually diffuse the gas at the nozzle mouth without pre-mixing, and then burn it. The combustion method is relatively simple, and the flame is relatively stable.
       Disadvantages: Due to the long flame, it is easy to produce incomplete combustion, which will produce more carbon monoxide and nitrogen oxides, which is not conducive to the full use of boiler fuel, the improvement of boiler thermal efficiency, and it is difficult to reach boiler emission standards.

2. Fully premixed combustion method
       Advantages: pre-mixing air and gas, heat transfer with multiple radiators, and increased heat transfer intensity. The advantage of using this combustion method is that the burning flame is clearer and the thermal efficiency is higher. Disadvantages: Combustion premixing ratio requires fast combustion rate, uniform combustion, high radiation heat transfer efficiency, flame temperature lower than 1200℃, no incomplete combustion and low NOx flue gas temperature, easy to condense, good heat recovery, and high efficiency.

3. Flameless combustion
       A combustion method that uniformly mixes the space before combustion with the gas in the gas boiler. When using this method, the oxygen required during the combustion process of the gas does not need to be obtained from the surrounding air, and only needs to be mixed with the air to reach the combustion zone to achieve instantaneous combustion completion.
      

It can be seen that there are currently three common combustion methods for boiler equipment. When purchasing a boiler, you can compare the advantages and disadvantages of the combustion method to select suitable boiler equipment.

How should a food factory choose a steam boiler of suitable tonnage?

For food processing plants, it is generally necessary to use a steam boiler to output a large amount of steam for each production process. The specific tonnage of the boiler depends on the actual steam demand in the plant area. Therefore, for food manufacturers, when purchasing steam boilers, they must know the amount of steam they need for their current production and the steam tonnage required for the later expansion of production. In this case, it is very helpful to calculate the required tonnage of the steam boiler. For steam boilers used in food processing, coal-fired boilers used to be the same as boilers in other industries. However, with the continuous stricter environmental protection policies in various regions, many companies have begun to choose clean fuel gas as fuel. The purchased boilers have also begun to use advanced technologies such as condensate recovery and have reached emission standards. Therefore, some customers recently consulted Fangkuai Boiler about the price of an environmentally friendly brewing steam boiler. This is because recently the environmental protection requirements in this area have become more stringent.

Recently, the Zhengzhou Fangkuai boiler manufacturer received an inquiry from a food factory. The company stated that it needed to purchase a steam boiler, but it needed to know the tonnage and price it needed. Because, after the pre-sales technicians of Fangkuai Boiler have a detailed understanding of the actual situation of the plant, they have calculated that the actual tonnage required by the plant is a 2 ton steam boiler that can fully meet the needs of production.

How much is an 8-ton steam boiler for food processing?

In the process of food processing and production in food processing plants, there are many procedures that require steam, such as disinfection, sterilization, encapsulation, etc.; therefore, one of the essential equipment in food processing plants is a steam boiler.

Recently, many food processing plants have inquired about steam boilers from Fangkuai boiler manufacturers about boiler selection, tonnage, operating efficiency, and selling prices. Zhengzhou Fangkuai boiler manufacturer provides a unified answer here.

First of all, the technicians of the Zhengzhou Fangkuai boiler manufacturer will recommend a suitable steam boiler for the user based on the actual processing and production conditions of the user's plant, and then calculate the price of the overall equipment. After calculating the output of the winery and the amount of steam required by the pre-sales engineers of Fangkuai boiler and the technical staff of the winery, it was concluded that the winery can use a 6t steam boiler. With a slight half ton of wealth, the production capacity can be increased in the later stage, and it is prepared. Currently, the price of a 6-ton steam boiler for Fangkuai boiler is around 500,000 yuan.

If the gas is different in some places, an electric steam boiler is needed. Recently, many wineries have asked Fangkuai boiler manufacturers for the price of large-scale brewing electric steam boilers. For the large-scale electric steam boilers mentioned by customers, this cannot be calculated because this is for the winery. The specific situation is not well understood, so it is necessary to communicate with the purchaser of the winery boiler in detail. After detailed communication, data show that the winery can use a 4-ton electric steam boiler. At present, the price of a 4-ton brewing electric steam boiler is around US$40,000.
