600MW机组W型火焰锅炉预防受热面超温的措施
摘要
分析了600MW机组W型火焰锅炉受热面超温现象
认为煤质差、锅炉蒸发受热面和减温水量设计偏小、卫燃带设计不合理等是产生超温的主要原因。对此
提出了具体的措施及建议并加以实施
较好地解决了受热面管壁超温问题。
Abstract
The over-temperature phenomenon of heating surface of W-shaped fire boiler equipped for 600 MW unit has been analyzed
it is believed that the main causes leading to over-temperature are in the following: bad coal quality; smaller designed value for heating surface of evapouration and for amount of desuperheating water; and unreasonable design of the refractory belt in furnace etc. . For these
concrete measures and recommendations have been put forward. After implementation
the over-temperature problem of tubes' wall for heating surface has been comparatively well solved.
