摘要

对华电邹县电厂四期超超临界机组7号炉后屏过热器泄漏原因进行了分析

认为主要因管子入口节流孔被堵塞

通流截面减少

蒸汽流量降低

冷却效果差

管子过热导致爆管所致。同时介绍了该锅炉的吹管工艺特点。

Abstract

The causes leading to rear platen superheater leakage for boiler no.7 of ultra-supercritical unit in fourth-phase project of Hudian Zhou’xian Power Plant have been analysed

it is believed that the main causes resulting in tube-burst are as follows: blockage of throttle orifice in the inlet of tubes

making the passage section to be reduced

the flow rate of steam to be decreased

the cooling effect to be bad

and the tubes to be overheated. At the same time

the features of pipe blowing technology for the said boiler has been presented.
