RESEARCH AND DEVELOPMENT OF LARGE CAPACITY CFB BOILERS IN TPRI

摘要

This paper presents an overview of advancements of circulating fluidized bed (CFB) technology in Thermal Power Research Institute (TPRI), including technologies and configuration and progress of scaling up. For devoloping large CFB boiler, the CFB combustion test facilities have been established, the key technologies of large capacity CFB boiler have been research systematically, the 100MW～330MW CFB boiler have been developed and manufactured. The first domestically designed 100MW and 210MW CFB boiler have been put into commericial operation and have good operating performance. Domestic 330MW CFB boiler demonstration project also has been put into commericial operation, which is H type CFB boiler with Compact heat exchanger. This boiler is China's largest CFB boiler.The technical plan of domestic 600MW supercritical CFB boiler are also briefly introduced.
