Chapter 1 Coal-fired Power Generation and Circulati

Of the total coal (black coal and brown coal) fired capacity, all except 140 MWe was based on the pulverized coal-fired technology. What is Circulating Fluidized Bed combustion (CFBC) CFBC units use bed materials (such as silica sand) to support the combustion of coal or any solid fuels around 900°C temperature to generate heat.

SHX coal-fired CFB (circulating fluidized bed) steam boil

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.

How Circulating Fluidized Bed Boilers Wor

Fluidized Bed. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air supply is from under the bed at high pressure. This lifts the bed material and the coal particles and keeps it in suspension. The coal combustion takes place in this suspended condition. This is the Fluidized bed.

Circulating fluidized bed - Wikiped

Introduction. Circulating fluidized bed is a relatively new technology with the ability to achieve lower emission of pollutants. Extensive research has been conducted on this technology within the past 15 years due to increasing concerns over pollution caused by traditional methods of combusting coal and its sustainability.

Fluidized bed combustion - Wikiped

Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.
