300MW低热值煤超低排放循环流化床发电的设计与运行
Design and Operation of a 300 MW Ultra-Low Emission CFB Boiler Burning Low Calorific Coal
摘要
Abstract
The paper introduces the design and operation of Shanxi Guofeng 300 MW ultra-low emission subcritical units burning low calorific coal.The principles and the application of the pollution controlling technologies are discussed.In this project,in-furnace desulfurizationand semi-dry flue gas desulfurization are used to control SO2,the low-nitrogen combustion technology based on the state specification theory and SNCR to control NOx,and bag filters to control powder.The results show that the boiler runs steadily and efficiently.The thermal efficiency at full load is 90.61％.The SO2,NOx and dust emission concentration at full load are 18.75 mg/m3,40.30 mg/m3 and 4.9 mg/m3,respectively,all of which meet the ultra-low emission standards.The results indicate that the low-NOx combustion combined with ultra-low emission technologies is applicable.关键词
