摘要

分析了蓄能降压联合一段吹管方式的技术要求

总结了某300 MW机组DG1089/17.4-Ⅱ1型循环流化床(CFB)锅炉吹管特点

包括:(1)吹管过程中燃油使用量大

投煤量小;(2)风烟系统阻力较大

系统压力梯度增加;(3)汽温受床温影响较大;(4)单次吹管持续时间较长。同时

给出了锅炉吹管过程中风烟系统、燃烧系统、给水系统的控制要点。

Abstract

The technical requirements of combined one section pipe-blowing mode with energy-storing and pressure-reducing have been analysed

and the pipe-blowing parameters being calculated

and determind.The pipe-blowing features of a DG1089/17.4-Ⅱ1 type CFB boiler for one 300 MW unit have been summarized as in the following:(1)small amount of adjustment in air and flue gas systems;(2)large consumption of fuel oil and little consumption of coal in the process of pipe-blowing;(3)the resistance in air and flue gas systems was larger increasing the pressure gradient in said systems;(4)the steam temperature is more affected by the bed temperature;(5)the CFB boiler has larger thermal storage

the duration of single time pipe-blowing has to be longer.The key points of control in air and flue gas systems

as well as in combustion system and feed-water system are given.
