摘要

四川白马循环流化床示范电站300 MW CFB锅炉飞灰气力输送系统存在管道堵塞、前后电场出力无备用和阀门频繁损坏等问题

对此

提出了改变省煤器与一电场连接方式

增大飞灰气力输送管管径

在进气阀和逆止阀之间加装"n"型连通管

将透气阀和气囊式圆顶阀更换为陶瓷双面闸板阀等改进措施。改造后

系统出力显著提高

运行可靠性明显增加

效果良好。

Abstract

The problems existing in pneumatic ash conveying system of 300 MW boiler in Sichuan Baima CFB Demonstration Power Station Co Ltd are Pipe blockage

without reserve output capacity in front and rear electric fields

and frequent damage of valves etc..For these

corresponding retrofit measures

such as increasing the diameter of conveying pipe

changing the connection scheme of economizer with one electric field

and additionally installing n-shaped connection tube between the air-inlet valve and the non-return valve

as well as replacing the air-intaking valve and the air-bag type domed valve with ceramic double-sided gare valve

etc.

have been put forward.After retrofitting

the output capacity of said conveying system has been remarkably enhanced

the reliability of operation being subsantially increased

having good effectiveness.
