Analysis and Discussion on Burning Low Calorific Value Fuel of Circulating Fluidized Bed Boiler

China's coal-dominated energy structure will not change in a short time. In order to implement the relevant national policies on conservation and emission reduction, it is good response adopt circulating fluidized bed boilers coal-fired power stations. Circulating boiler adopts combustion, which has high reliability utilization rate because of its special combustion mode particle recycling device. For low calorific value inferior fuel difficult burn common boiler, CFB also certain adaptability compatibility. this background, article with coal gangue as representative are discussed application process, equipment fly ash produced by proposed that often appear three aspects problems, accordingly put forward solution optimization measures, provides reference for actual process.
