1, adjust and optimize the industrial structure, strictly control the "two high" industry capacity. And resolutely put an end to "scattered dirt" projects and has been banned "scattered dirt" off-site transfer business. Since October 1, 2018, thermal power, petrochemical, chemical, carbon, industrial boilers and cement and other industries, the implementation of air pollution emission limits in particular, to promote pollution control in key industries.
2, speed up the adjustment of energy structure, promoting clean efficient heating. The pooling of resources and vigorously promote the coal for governance, before the heating period in 2020 basically completed the life and motivations of heating coal for alternatives to achieve the task of clearing the loose coal. Is expected before the end of December 2018, the urban built-up areas out of 35 steam tons / hour coal-fired boilers, encourages other regions to advance out of 35 steam tons / hour coal-fired boilers. At the same time accelerating the transformation of low nitrogen gas boiler NOx emission after the transformation shall not exceed 50 mg / cubic meter.
Low NOx emission combustion boiler coal fluidized bed argentina 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.
Development of CFB for power generation has been ongoing for several decades. At the end of the 1970s,First introduced CFB combustion technology originally developed for heterogeneous reactors, to the field of coal combustion. CFB operation is characterized by rapid gas–solids mixing, reactions, and heat transfer, all of which create an environment in which low-grade solid fuels can be stably burned at 800–900°C. At these relatively lower temperatures, NOxformation and emissions are much lower than what is observed for PC combustion. In addition, limestone additives can be combined in the boiler coal fluidized bed argentina to capture the SOxin situ. Therefore, CFB offers the least expensive means to control NOxand SOxemissions from coal combustion. Other environmental benefits, such as waste reduction and a smaller carbon footprint, can also be achieved through cofiring coal with biomass or waste. As CFBs are inherently fuel flexible, they can readily accept lower rank fuels that can be varied over time pending availability and other factors.
The larger fuel flexibility of CFB power station boiler coal fluidized bed argentina in Iraq is applicable for the clients need various choices,which can use biomass,various kinds of coal include hard-to-burn fuels,low-grade fuels and waste.
Biomass CFB boiler is designed on the base of our experience of circulating fluidized bed boiler. Low temperature combustion technology is adopts to have the pre-processed biomass fuel and mineral fuel fired mixedly, it can both lower the operation cost and improve the combustion efficiency and reduce emission density of the pollution gas, such as SO, NO, etc. Especially, it has less effect on the heating surface by the high content of Cl, Sulfur in the biomass fuel, in this way, it has less
Get A QuoteAtmospheric fluidized beds use limestone or dolomite to capture sulfur released by the combustion of coal. Jets of air suspend the mixture of sorbent and burning coal during combustion, converting the mixture into a suspension of red-hot particles that flow like a fluid. These boilers operate at atmospheric pressure.
