300MW循环流化床锅炉减排与辅机节电

节能减排是国家“十一五”规划的重点目标之一，基于我国电力工业由于火电机组比重高，消耗和排放的二氧化硫均占全国总量的一半以上，国家对火电厂的节能减排工作尤为重视。着重介绍了近年国家大力推广的大型300MW循环流化床锅炉。在实际运行中可通过合理安排辅机的启停、采用变频调速技术等措施实现电厂节能，通过向炉膛添加石灰石粉等方法促进SO2减排。

Emissions reduction for 300 MW circulating fluidized bed boiler and energy conservation of auxiliary facilities

Energy conservation and emissions reduction are key targets of the 11th five-year plan.According to high proportion of thermal power units,both coal consumption and SO2 emissions quantity account for more than half of the total.Great importance is attached to power conservation and emissions reduction in thermal power plants.The paper introduces 300 MW circulating fluidized bed boiler widely popularized.Power conservation can be achieved by arranging start-stop of auxiliaries and variable frequency speed regulation.Emissions reduction can be achieved by adding limestone into furnace.
