Research and development on circulating fluidized bed combustion technology in China

The paper reviewed the present status of the circulating fluidized bed (CFB) technology in China, especially in the fields of research and developmental tendencies. Circulating fluidized bed boilers are becoming larger capacity with supercritical parameters, more intensified desulphurization and denitrification as well as multi-purpose utilizations. At present, China has capability to design and manufacture circulating fluidized bed boilers up to 450 t/hr. One of the largest size CFB boiler in the world applied in a 300 MWe power plant was manufactured and constructed with a licensed technology in Sichuan Province, China. Technologies for supercritical CFB boilers at 2000t/hr capacity level are also under researching and developing.
