我厂于1993年4月新安装了一台KZW_4—1.25—A_1型4t/h快装锅炉,后另配置了XDN型多管除尘器,除尘效果较好。但由于该除尘器阻力较大,使引风机(Y5—47No6C)的出力与锅炉整体要求不匹配,致使锅炉正压燃烧。自去年4月正式使用后,经常烧坏炉排,甚至烧坏炉排大梁和保温砖,维修费用已达2万元。如更新引风机,有一定实际困难,决定对原引风机进行技术改造。 我们通过测试并查阅了有关资料,认为用改变风
I plant in April 1993 to install a new KZW_4-1.25-A_1 4t / h fast boiler, the other configured XDN-type multi-tube dust collector, dust removal effect is better. However, due to the larger resistance of the precipitator, so that the induced draft fan (Y5-47No6C) output and the overall requirements of the boiler do not match, resulting in positive pressure boiler combustion. Since it was officially used in April last year, it often burned grates and even burned grate girders and insulation bricks, and the maintenance cost has reached 20,000 yuan. Such as updating the induced draft fan, there are some practical difficulties, decided to make the original draft fan technological transformation. We passed the test and access to relevant information, that change with the wind
