摘要

在对大唐红河发电有限公司300 MW循环流化床(CFB)锅炉特性分析的基础上

对一次风控制系统、运行方式、二次风配风、高压流化风系统等进行了优化。优化后

提高了一次风控制系统的调节品质和锅炉使用寿命

改善了炉膛燃烧

显著减少了过、再热蒸汽温度超温和机组非计划停运次数

降低了厂用电率

满足了电网对机组降负荷速率的要求。

Abstract

Based on analysis of characters of boiler equipped for 300 MW unit in Datang Honghe Power Generation Co Ltd

the control system of primary air

the operation mode

and the distribution of secondary air

and the high-pressure fuidized air system have been optimized.After optimization

the regulation quality of primary air control system and the service life of boiler have been enhanced

the combustion in furnace being improved

the times of overtemperature for superheated and reheated steam

as well as the times of non-scheduled unit shutdown being greatly reduced

the consumption rate of service power being decreased

satisfying the requirement of power grid for load-reducing rate of unit.
