摘要

以唐山开滦东方发电有限公司490t/h循环流化床(CFB)锅炉的燃烧系统为研究对象

对1号CFB锅炉110MW和140MW负荷燃烧调整参数进行了对比分析

研究了煤种特性、一次风率、二次风压、返料量等调节变量对床温、飞灰含碳量等被控量的影响规律

可为CFB锅炉机组高效运行提供参考。

Abstract

Taking the combustion system of 490t/h circulating fluidized bed(CFB)boiler in Tangshan Kailuan Dongfang Power Generation Co.

Ltd.as the research object

the combustion adjustment parameters of the No.1boiler at 110MW load and 140MW load were compared.Moreover

the effects of such adjustment variables as coal property

primary air rate

secondary air pressure and recycle stuff amount on controlled variables like bed temperature and carbon content in fly ash were investigated.The results can provide references for CFB boilers' efficient operation.
