Introduction

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 NOx 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.
