Low NOx emission combustion coal fired boiler manufacturer list malacca city technology a boiler combustion boiler hypoxic hypoxia NOX emissions from combustion is the easiest way to control. And a combustion burner system does not need to make any changes, only control air flow into the furnace in operation, pulverized coal combustion process as close to the theoretical combustion air amount. Low oxygen combustion scheme can reduce NOX emissions by 20% to 30%. The program practical application subject to conditions. Low oxygen furnace, will increase the amount of unburned carbon, and more difficult for the flame of burning coal more obvious; Further, the CO concentration is also increased so that smoke, which will cause decreased boiler efficiency. Another problem is that for certain boilers, hypoxia causes the main combustion steam or reheat steam temperature is low. The burning coal to immediately, boiler efficiency and reduce the magnitude of steam temperature and other properties to determine the appropriate control value of flue gas oxygen furnace outlet (at or economizer) the specific embodiments. Second, air staged combustion technique combustion air into a plurality of strands, it is gradually mixed and pulverized coal combustion, so you can see the local area to reduce the air-fuel ratio, and the thermal decomposition of coal in the ignition phase, due to hypoxia, and thus the nitrogen oxide generation is suppressed. Air classification may be implemented within the combustor, the boiler can be completed within. 85% of the amount of air required for complete combustion is introduced to the main burner, the main burner combustion zone is insufficient oxygen for the fuel-rich conditions. Due to insufficient amount of oxygen, the flame temperature is low, the amount of nitrogen oxides to less generation of fuel nitrogen intermediates (e.g., NCH, NH3, etc.) will therefore not be oxidized NOX. Meanwhile, it has been possible to further reducing NOX generated in a reducing atmosphere to molecular nitrogen (N2 of), as a result reduces NOX emissions. An upper portion of the top floor is provided Ge overfire air (of OFA) spout into the furnace through which about 15% of the rest of the air, to avoid the high temperature flame zone, it is also possible to burn unburned carbon particles, to complete the combustion process.

Tai Chi, Jiaozuo City, Jiaozuo City Sports Center is one of important sports infrastructure, a total area of ​​11.73 hectares, held several international events. With strict management in Henan Province for air emissions of pollutants, Jiaozuo City, also launched the governance of coal-fired coal fired boiler manufacturer list malacca citys, thermal power and other equipment. Jiaozuo Sports Center actively cooperate with municipal workers, took the lead from coal to gas activities, the serious pollution of the original extent of coal-fired boilers to replace gas boilers. Gas boiler cleaning binding understanding of the market, to achieve cooperation with the finalization fast boiler by providing a fast side 2.8MW integrally condensing gas hot water boiler (WNS2.8-1.0 / 95/70-YQ), it is used to Sports Center provides heating and hot water.

Condensing gas coal fired boiler manufacturer list malacca citys and gas boilers ordinary What are the differences: In recent years our country has become increasingly serious air pollution, has been the concern all sectors of society, the government has come to realize the seriousness of the problem. Pollution Control Act have been amended from the air, you can see the degree of importance to the matter of the government, this year the country launched campaigns coal to gas boilers.

Instead of gas-fired coal fired boiler manufacturer list malacca city coal-fired boilers has become an inevitable trend of more and more common as the use of gas, China's energy structure has undergone tremendous changes. In the future for a long period of time, gas and coal is still the main source of energy, how to weigh the severity of it in small series for everyone here today about the analysis and comparison:? Although there are many drawbacks of coal-fired boilers, but in the national economic development has an irreplaceable role, he plays an important role in the past for a long time. Because all the advantages of gas-fired boiler, will become a major force in the development of national energy policy boiler. Instead of gas-fired boiler coal-fired boilers has become an inevitable trend. Coal-fired boilers are in a very long time the main products of heating, but there are many drawbacks: such as low thermal efficiency, energy waste, due to the high sulfur content coal, to atmospheric pollution. In recent years, the contradiction between supply and demand of energy and environmental pollution have become increasingly prominent. Compared with coal and gas, is one of the most clean fuel, he combustion, high thermal efficiency, low air pollution, good environmental performance.
