用循环流化床技术对煤粉锅炉进行改造的前景分析

Prospect Analysis on Reformation of Powdered Coal Fired Boilers Using Circulating Fluidized Bed Technology

循环流化床是新一代高效、低污染清洁燃烧技术 ,发展这种技术并用它来改造或替代旧煤粉锅炉 ,可以达到节约资金、减少污染、增容和延长电厂使用寿命的目的。文章根据国内外循环流化床锅炉的一些技术信息 ,对大容量煤粉锅炉 ( 4 1 0 t/h以上 )采用循环流化床技术进行改造的前景进行了分析 。

WT5BZ]Circulating fluidized bed is a clean combustion technology of new generation with high efficiency and low pollution.Developing and using this technology to reform of replace the old exist powdered coal fired boilers can achieve the purpose of saving money,reducing pollution,increasing the capacity of the boiler,and prolonging the service life of the plant.According to the information from China and abroad,this paper analyzes the prospect of using circulating fluidized bed for the reformation of large capacity boilers(above 410t/h).Some suggestions are also proposed.
