煤气换热器损坏原因分析及解决方案

针对鞍钢1700 ASP生产线加热炉煤气换热器损坏问题,从煤气换热器本身构造及外部环境进行系统分析,并采用化学检测等方法确定了换热器损坏的直接原因,具体为煤气管道中的水进入换热器内造成温度应力、内部煤气分流不均、空气换热器换热效果不佳等,并提出了改进煤气换热器结构、加大煤气管道排水能力、增加空气换热器换热而积的策略.

Catse Analysis of Damage Reason of Gas Heat Transfer and Solutions

Aiming at the gas heat transfer damage problem of heating furnace in Ansteel 1700 ASP production line,systemic analysis was done from the gas heat transfer itself structure and external environment,and the direct damage reasons were determined by using chemical testing methods,which included the temperature stress caused by the water of gas pipes into the heat transfer,the uneven distributed internal gas,the bad heat transfer effect of the air transfer,and so on.The treatment strategies were promoted such as improving the structure of gas heat transfer,increasing the gas pipes drainage efforts,and increasing the heat transfer area of air heat transfer.
