摘要
某1 000 MW机组锅炉渣水循环系统长期运行后,高效浓缩机、集水池及相关坑泵严重积渣堵塞,影响捞渣机正常补水降温。在充分调研及系统试验的基础上,对捞渣机进行无溢流改造,取消渣水循环系统,强化捞渣机补水。捞渣机无溢流改造后,系统运行稳定,缺陷率明显降低,且节能效果显著。
Due to long-time operation of slag water circulating system of 1 000 MW boiler units , high-effi-ciency thickener, collecting basin and pit pump are blocked by deposited slag, which has great impact on water supply for cooling of slag salvaging machine. On the basis of investigation and system test , the slag salvaging machine is transformed without overflow： eliminating slag water circulating system , strengthening water supply of slag salvaging machine. After the transformation , the system operates stably , the defects are obviously reduced and the energy saving effect is significant.
