补水率大汽机方面查哪些地方?

答案

参考答案:

查对外供汽量、生活用汽量、暖通用汽量,扣除后,一般每班补水量超过100t(炉水水质正常情况下),并且和化学报来的补水量基本一致。实际用补水箱下降校对基本一致时,说明补水量确实大。

⑴连排水位调整门,炉水水质正常其开度正常在5~15%,不超过20%,旁路门不开,超过此值,说明炉侧开得过大;

⑵闭冷器是否内漏,可关闭进水,检查水位下降情况;查闭式水箱是否溢水(闭式水漏到开式水侧,使闭式水补水增加,进而影响补水率);

⑶查给水管路有压、无压放水总管,若烫手再细查给水泵出口及高加水路各放水阀、放气阀;查凝结水管路(包括除盐装置)放水阀、前置泵进口门前放水阀、前置泵出口放水阀、给水泵放气阀、给水泵中间抽头放水阀;各加热器汽侧放水阀;

⑷查定子水箱溢流、真空泵排水量大小(内漏)。
