摘要

针对珠江电厂 2号炉末级再热器AB侧烟温偏差较大

末级再热器后局部烟温比设计烟温高的问题

使用CFXTASCFLOW三维流动燃烧传热计算软件对炉内燃烧工况进行模拟计算

最终确定了燃烧器反切改造方案

并在改造方案实施后对锅炉燃烧进行了优化调整。测试结果表明

燃烧器改造后末级再热器AB侧烟温偏差下降了 36℃

断面最高烟温平均下降了 30℃

末级再热器管壁最高温度下降了 4℃～ 10℃

减少了锅炉超温爆管的危险

有效保证了锅炉安全经济运行

Abstract

In the light of troublesome problems occurred on boiler No.2 in Zhujiang Power Plant

such as larger deviation of flue gas temperature at A

B side after final stage reheater

and temperature of partial flue gas being higher than the designed value

analog computation of combustion performance in the furnace has been carried out by using the CFX-TASCFLOW heat transfer calculating software for three dimensional flowing combustion

and finally a scheme of reverse tangential retrofitting of the burners is determined

and optimizing adjustment of combustion in the boiler is performed after implementation of the retrofitting scheme. The results of test show

after retrofitting the burners

the flue gas temperature deviation at A

B side having been lowered to be 36℃

the max

flue gas temperature evenly lowered to be 30℃

the max

tube wall temperature lowered to be 4～10℃

the risk of boiler tube burst due to over temperature being reduced

effectively ensuring safe and economic operation of the boiler.
