摘　　要：为改善煤炭利用带来的污染问题,煤炭正在向规模化、集中化的趋势发展,入选原煤比例日益提高。在此过程中产生了大量的煤泥等残余物。同时,煤炭价格不断上涨,加之环境保护的问题日益突出,开发大比例掺烧煤泥的大型循环流化床锅炉势在必行。大比例掺烧煤泥的技术关键是应针对煤泥的成灰特性考虑气固两相流态的选择,实现稳定、高效燃烧;在此过程中充分考虑烟气量对汽水系统的影响;第三是煤泥的输送问题。In order to control the coal emission,the ratio of the coal for washing is increasing due to the coal mine size and its centralization.However,a large mount of peat is byproduced in coal washing process as residue, which is very difficult to treat.In the same time,the coal price rise constantly.This forces the development of the large circulating fluidized bed boiler firing peat as mean fuel to prevent the peat emission.The key technology of the large circulating fluidized bed boiler firing peat as mean fue...
