customized circulating fluid bed with best price
Due to enhancement of the environmental awareness in all sectors of society, environmental protection products have developed rapidly and the technology of circulating fluidized bed boiler has matured. Whether the large size of the boiler itself or its various matching technologies and equipment have already adapted to various user requirements. The circulating fluidized bed boiler produced by our company can better adapt to the distribution and area of the domestic coal resources. Meanwhile,CFB Boiler according to customer needs, domestic garbage, sludge and biomass can be mixed and burned, and the advanced combustion technology can achieve high combustion efficiency and reduce environmental pollution. On the basis of successful operation of circulating fluidized bed boilers made by partner manufacturers, our Company has successfully developed and manufactured the circulating fluidized bed boilers of the 20-220t/h parameter levels with the following characteristics:
1.Boiler efficiency ≧ 90%;
2.Steam-cooling (water-cooling) volute-type cyclone separator;
3.Steam-cooling (water-cooling) wrapped wall structure is adopted in the rear superheater area;
4.The rear economizer guard-plate furnace wall adopts the guard-plate frame-type light walls, and the boiler has good sealing performance;
5.Steel structure design: The boiler structure is strictly calculated with finite elements to ensure reasonable load distribution;
6.Optimization of the primary/ secondary wind ratio can reduce the power consumption, enhance the disturbance of flue gas to prolong the residence time of flue gas in the furnace and improve the boiler efficiency;
7.Large cross section of hearth, long-time stay of flue gas in the furnace, low rising speed of furnace, large circulating amount in the furnace, increase of the primary burnout rate, and significant reduction of the abrasion of the water-cooling hearth wall area.
