Latest Development of CFB Boilers in China

The circulating fluidized bed (CFB) coal-fired boiler has being rapidly developed in China since 1980s and becomes a key clean coal technology used in thermal and power generation. In this paper, the development history and development status of the CFB boiler in China are introduced. The development history of the CFB boiler in China is divided into four periods and the important features of each period are given. Some latest research activities and important results on CFB boilers, and the typical achievements and newest development of the CFB boiler in China are also introduced. In addition, a few challenges and development directions including the capacity scaling up, SO2 removal and energy saving are discussed.
