Circulating fluidized bed(CFB) boiler is the main technical mean for clean and efficient utilization of low calorific value fuel and hard-to-burn coal

and is also an important part of thermal power generation in China.By the end of 2018

a total number of 440 large-scale CFB boilers with capacity of above 100 MW(410 t/h) had been put into operation in China

and the total installed capacity had exceeded 82.3 GW. The unit capacity

installed scale and technological advancement of CFB boilers have reached the world's leading level. This paper introduces the development history and application status of CFB boilers in China

and analyzes the application fields

main models

unit distribution

major technical and economic indicators in recent years. Moreover

from the perspective of capacity parameter

technology standard system

international application

operational flexibility

fuel adaptability and so on

the development of CFB boiler technology in China is forecasted.
