Two 300MW circulating fluidized bed boilers in Diaobingshan Gangue Power Plant have been put into operation since 2009 and 2010. Because the separator is in a high temperature and high circulating ash operating environment, the inner cylinder of the separator is worn and deformed rapidly, and the efficiency of the separator is greatly reduced, resulting in excessively high bed temperature and separator temperature, an increase in the original amount of environmental protection, and an increase in the cost of environmental protection materials, which affects the safe and economic operation of the unit. In view of this phenomenon, Diaobingshan Coal Gangue Power Plant has improved the efficiency of two furnace separators. After the transformation and operation, the bed temperature and the outlet temperature of the separator have dropped significantly during the operation of the unit, and the original amount of environmental protection has dropped significantly, and the consumption of environmental protection materials has dropped significantly, and the energy-saving effect is remarkable.展开更多
