As a new mature high-efficiency and low-pollution clean coal technology, circulating fluidized bed combustion (CFBC) technology has many advantages that other combustion methods do not have. Circulating fluidized bed combustion is low-temperature combustion, so the helium oxide emission is much lower than that of pulverized coal furnace, only 200ppm. CFBC can desulfurize directly during the combustion process, and the desulfurization efficiency is high. The technology and equipment are simple and economic, and the costs of its initial investment and operation are much lower than those of dry pulverized coal furnace and flue gas desulfurization (PC+FCD).
Wide adaptability fuel and high combustion efficiency, especially suitable for low calorific value inferior coal.
The discharged ash residue has good activity and is easy to be comprehensive utilized without secondary ash residue pollution. The load adjustment range is large, and the low load can be reduced to about 30% of the full load.

01High temperature cyclone separator
|High efficiency, wear resistance, separation efficiency ≥ 98%, effectively improve the combustion efficiency of the boiler thermal efficiency.|
02Large furnace design
03Bell jar type hood
|Adopt bell jar type hood to distribute air average and avoid fuel returning to wind chamber.|
04Low bed pressure operation
|Through particle optimization, the operating bed pressure can be as low as 3500 Pa, which effectively saves operating costs and greatly reduces the production of NOx.|
