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). 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.
Adopts the latest scientific and technological achievements of Tsinghua University, which was listed as the State Education Commission major scientific and technological projects, the Ministry of Science and Technology "national scientific and technological achievements to promote the plan."
High efficiency, wear resistance, separation efficiency ≥ 98%, effectively improve the combustion efficiency of the boiler thermal efficiency.
Large furnace, low velocity design; the application of wearproof tube technology, reducing erosive abrasion;Extend the residence time of coal particles in the furnace so that the coal can be fully burned.
Widely fuel availability is CFB power plant boiler’s another advantage. Provided more fuel choices, boiler users tend to burn low quality coal or biomass fuels to save its fuel expense. CFB power plant boiler can burn a wide variety of solid fuels, even including low value coal fuel, such as anthracite, bituminous, lignite, wood residue, etc.
