China coal fired boiler machine

1, should guarantee the smooth flow of flue gas, have a good fullness and should avoid dead ends and dead.

2, the burner should be provided at the height position of the center of the furnace, and the combustion space and has sufficient length. Flame should not be flushed to the wall heating surface, so as to avoid incomplete combustion gases local overheating and damage to the wall.

3, since the combustion gas in the furnace backlash, high thermal strength, exposed to the bottom of the drum in the furnace should be adiabatic process.

4, various pipes, fire tube boiler furnace wall substantially refractory brick masonry, and shield plus insulation material. In the "coal to gas" should pay attention to the tightness of the furnace wall, minimizing the original door, door checks, etc., can assemble the refractory block, prevent cold air flames wounding or excessive leakage into the furnace , affecting boiler efficiency, to see the fire hole must remain closed also should see the fire hole, heat-resistant glass viewing by fire.

5, the furnace boiler and gas than coal-fired boilers, is generally greater, there is sufficient combustion space, increase the volume of gas, does not affect the transformation of combustion conditions. If the user requests output significantly improved boiler, the furnace can be increased radiation heating surface, to remove scale and soot while the inner surface of the outer heating of the original, so that without increasing the volume of the boiler case to improve the boiler output is not a problem. Thermodynamic calculations must do in the boiler, while the smoke but also good wind resistance calculation intensity calculation.

The difference between Henan coal-fired china coal fired boiler machines and gas boilers no matter what gas or coal can be used as fuel for boilers, however, named according to different types of boiler fuel use are not the same, so there is a gas boiler Henan and gas boiler that different types of boilers. So both types of boilers in addition to the fuel used in the combustion is not the same, between Henan coal-fired boilers and gas boilers, what difference does it make? 1, different heat loss in order to allow coal-fired boilers to maintain sufficient combustion efforts require the use of human or other device to stop adding coal-fired furnace, when the need intermittent operation, it takes a long time to start to increase again furnace temperature, it will generate a lot of heat when the pressure of the fire damage, while Henan gas boiler start and stop very convenient, fast warming intermittent operation, thereby reducing heat loss in this process. 2, after the treatment of different coal-fired combustion in the boiler will produce large amounts of ash after combustion, in order to maintain a good healthy environment need to transport ash to the professional field slag processing, however, gas-fired boiler using gas , there will be no remaining after combustion ash, there is no need to process it, not only to avoid environmental pollution also reduces the labor intensity and the amount of urban ash storage and transportation companies. 3, the fuel is coal flue gas of coal-fired boilers used in different, when coal combustion will have a greater smoke caused serious pollution to the environment, however, high stability of the gas after combustion boiler did not smoke exhaust, because the basic gas on can be completely burned, toxic black smoke can reach zero ringelman level, SO2 content of which is very small, so there is no pollution to the environment. These three points above are some of the differences between Henan coal-fired boilers and gas boilers. By introducing the above we can understand the essential difference between the two boilers can understand, Henan gas boiler it is because of more environmentally friendly energy was gradually replace coal-fired boilers.

To build greener homes, recently, the ecological environment of the Office of Hebei Province issued "on improving air quality guidance on the implementation of regional differentiation of access environment." "Opinions" clearly states: Shijiazhuang, Baoding and other eight cities as a red zone atmospheric transmission channel, a ban on new industrial projects and expansion of 10 large iron and steel, thermal power, cement and so on.

"Opinions" also pointed out that the province's administrative regions and the municipalities and districts male An District, Dingzhou City, Xinji City administrative area, is strictly prohibited new construction, expansion (except for cogeneration and the same amount of alternative projects) coal; a ban on new , expansion of production capacity of iron and steel, cement, plate glass, petrochemicals project (excluding off-site relocation of upgrading) and 35 tons of steam coal-fired boilers; prohibit new emissions intensity below the access conditions of other industrial projects.

Handan, Xingtai, Shijiazhuang, Baoding, Langfang, Tangshan, Dingzhou, classified as a red zone xinji atmospheric transmission channel. Within this administrative area (except city back removal capacity), to prohibit new and expanded (except equivalent replacement) steel, thermal power (except CHP), coke, cement, lime, gypsum, fertilizer, general casting of ferrous alloys, iron alloys smelting, carbon, other industrial projects using coal as a fuel; Jing Kun high-speed east, north wing black high speed, and Langfang, Baoding and Beijing bordering county area designated as coal ban areas, not in addition to the approval of central heating coal-fired project.

Future, Hebei Province, will strengthen self-examination, government oversight and something in the ex post regulation, the implementation of various construction projects of environmental protection requirements as well as changes in environmental quality, pollutant emissions such as the implementation of dynamic monitoring of the implementation of environmental access requirements for non-construction strictly punished according to the law project, supervise the rectification of the problem is serious, shut down or banned. Meanwhile, according to relevant laws and regulations, environmental protection requirements and regional environmental quality changes and other regional differentiation environmental access requirements will be adjusted in due course.

How to choose a reasonable price brand of industrial china coal fired boiler machines How to choose a reasonable price brand of industrial boilers How to choose a reasonable price brand of industrial boilers, fuel gas-fired boiler, good insulation properties, clean and green, the boiler thermal efficiency advantages, is currently popular on the market a boiler in addition to the gas boiler has its own characteristics, the full implementation of the national coal policy to further promote gas-fired boiler coal-fired boiler to become the user's preferred furnace, gas boiler market demand continues to grow. There are many brands on the market boilers, boiler quality is not uniform. For users, how to choose the right brand of industrial boilers price is very important. How to choose the affordable brand of industrial boilers, we all know that smoke respirable particulate matter is the culprit, but in fact, another reason - nitrogen oxides can not be ignored. Project promotion, gas boilers ownership will continue to increase. Coal combustion gas may reduce the pressure of the coal, to reduce the concentration of airborne particulate matter, nitrogen oxides, but also an important reason for the smoke, which generates an important condition is a high temperature. Gas boiler for heating and the heating temperature needs. Many gas SO2 emissions from large boilers on the one hand is greatly reduced, on the other hand produce large amounts of nitrogen oxides. Fast side gas boiler gas boiler can be reduced to nitrogen oxides emission concentration 30mg / m or less. With the implementation of the new emission standards across the country over the next three to five years to use low nitrogen gas boiler to improve the cleanliness of a large number of industrial buildings and residential heating gas boiler emissions.
