广东粤嘉电力有限公司5、6号机组于2005年11月及2006年3月投入商业运行,为燃用本地无烟煤而设计制造的440t/h循环流化床锅炉,为适应燃料多样性,将锅炉改为掺烧烟煤的CFB。锅炉设计燃用无烟煤与掺烧烟煤煤质主参数见表1;每台锅炉从4台给煤机来的煤粒经播煤风送入炉膛前墙后,迅速被炉膛内存在的大量惰性高温物料包围,着火燃烧,与石灰石发生脱硫反应;一次风经一次风空气
Commercial units of Units 5 and 6 of Guangdong Yuejia Electric Power Co., Ltd. were put into commercial operation in November 2005 and March 2006. The 440t / h circulating fluidized bed boiler designed and manufactured to use local anthracite, in order to meet the fuel diversity, The boiler was changed to CFB mixed with bituminous coal. The main parameters of coal burning with anthracite and coal with bituminous coal are shown in Table 1. The coal particles from 4 coal feeding machines of each boiler are sent to the front wall of the furnace through the sowing coal and quickly swelled by the large amount of inert high temperature Surrounded by materials, burning fire, desulfurization reaction with limestone; a wind by a wind air
