【Abstract】 The progress and key technology research on ultra-supercritical CFB technology of research institutions and boiler manufacturers at home and abroad were expounded, and then furnace type of ultra-supercritical CFB of boiler manufacturers at home were also introduced in detail. To research and develop ultra-supercritical CFB boiler technology, key technological difficulties were analyzed from heating surface safety, hydrodynamics safety, maintaining reheat steam temperature at low boiler load and low-cost ultra-low emission technology, and then the solutions to these difficulties were put forward. It guarantees the research and development of ultra-supercritical CFB boiler and provides technical support to continue to maintain the leading position of China’s CFB power technology.更多还原
