Coal Fired CFB Steam Boiler 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.

 

DHX Series Steam Boiler Advantage

CFB coal fired steam boiler is widely used in the field of power generation and industrial production in thermal power plants. The series of coal-fired boilers can be divided into circulating fluidized bed power station boiler,DHX type circulating fluidized bed boiler and SHX type circulating fluidized bed boiler according to the boiler type. High combustion efficiency, high thermal efficiency, smoke exhaust in SO2, NOx and other harmful gas content. DHX type CFB coal fired boiler overcomes the problem of high power consumption and high wear of conventional CFB boiler, which greatly reduces the boiler wear problem.
