Biomass fired dzl biomass fired 1 ton steam boiler combustion process
The biomass fuel is fed into the furnace screw feeder, where due to the high temperature flue gas and the role of the primary air gradually preheating, drying, fire, burning, this process a large number of volatile precipitation, burn vigorously. After the resulting erosion main heating surface temperature flue gas boiler, the boiler economizer heating surface of the tail and air preheater, and then into the dust, and finally through the chimney into the atmosphere. Not gasified fuel side to the rear of the grate movement until burnout, the last remaining small amount of ash fall behind the grate slag mouth.
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 does the CFB boiler work
CFB technology burns fuels without fire or burners in the furnace but through a process of fluidization mixes the fuel particles with limestone which captures the sulfur oxides that are formed and the low temperature reduces nitrogen oxide formation. The limestone and fuel are recycles multiples times which increases both the efficiency of producing high quality steam to produce power and also reduces pollution due to its ability to burn fuel in a clean way than the conventional processes. Circulating fluidized bed technology(CFB) also offers the flexibility of using both coal as well as biomass fuels.
Fluidized Bed Combustion (FBC) dzl biomass fired 1 ton steam boiler
Fluidized bed combustion (FBC) steam boiler for biomass boiler has emerged as a viable alternative and has significant advantages over conventional firing system and offers multiple benefits–compact boiler design, fuel flexibility, higher combustion efficiency and reduced emission of noxious pollutants such as SOx and NOx. The fuels burnt in these boilers include coal, washery rejects, rice husk, bagasse & other agricultural wastes. The 15ton hour coal fired fluidized bed boilers have a wide capacity range- 0.5 T/hr to over 100 T/hr.
