OPERATION EXPERIENCE AND PERFORMANCE OF THE FIRST 300MWe CFB BOILER DEVELOPED BY DBC IN CHINA
In this paper, general layout, design, operational experience and performance of the first 300MWe circulating fluidized bed (CFB) boiler that developed by Dongfang Boiler Group Co., Ltd China, are introduced. The furnace was with large width-depth ratio. The problems occurred during in commissioning were analyzed and the corresponding modifications were presented. Cold-state experiment and operation experience showed that both fluidization quality and circulating flow rate meet the designated value in the frunace. The imbalance of circulating material flow caused by asymmetric layout of three cyclones was very limited. Heating surfaces were safe except wing wall superheater located in upper part of the furnace was overheated at low load. After commissioning, the boiler was correspondingly modified and its performance was excellent.
