我厂2号机组容量为125MW,1983年8月投产,累计运行12万h,锅炉型号为SG420/140-M414,原配备两台回转式空气预热器,回转直径6.2m,受热面积18500m2/台,设计值为:漏风率小于15%,热风温度342℃,排烟温度133℃,锅炉效率91.06%。由于设备老化,腐蚀严重,多年来,两台空预器漏风率?..
Our plant No. 2 unit capacity of 125MW, put into operation in August 1983, the cumulative operation of 120,000 h, the boiler model SG420 / 140-M414, the original equipped with two rotary air preheater, turning diameter 6.2m, heating area 18500m2 / Taiwan, the design value is: the air leakage rate is less than 15%, the hot air temperature is 342 ℃, the exhaust air temperature is 133 ℃ and the boiler efficiency is 91.06%. Due to aging equipment, serious corrosion, over the years, two empty pre-air leakage?
