摘要
介绍1025 t/h锅炉过热器喷水减温器的特点和运行情况,分析了温度应力引起的减温器失效的原因,其中设计材质不良、检修不及时、运行调节不佳是可以避免的。从更换材质、定期检查维修和加强运行调整等方面提出了由于减温器失效引起锅炉停运的处理办法。
This paper introduced the characters and operation status of the spray desuper-heaters of 1 025 t/h boiler. By analyzing the causes why the desuperheaters have crack failures, the paper pointed the main factor is temperature stress. Among those causes, unreasonable material selection, less timely repair and wrong operation can be avoided. It also proposed some countermeasures for preventing boiler off line due to desuperheaters' failures.
