1025t/h锅炉再热器微量喷水减温器泄漏原因及对策

Leak Cause of Micro Spray Water Desuperheater of 1025 t/h Boiler Reheater and Countermeasure

对1025 t/h锅炉A再热器微量喷水减温器管接头焊缝裂纹原因进行了分析,确认其裂纹产生原因不是常规的金属材料及焊接质量问题,而是由部件组装间隙不合格及喷水装置强度低所造成。并采取了有效的治理措施,取得了良好的效果。

This paper analyzed the weld crack cause of the micro spray water desuperheater tube joint of 1 025 t/h boiler A reheater, it considers that the crack is not caused by metal material and welding quality, but by incorrect assembly gap and low strength of spray water device, and effective improving measure was adopted ,and obtained good results.
