摘　　要：针对华电六安发电有限公司2×135MW机组循环流化床锅炉空预器漏风率严重超标问题,提出了通过对空预器全面查漏、换管改造来降低漏风率等改造措施。改造后达到预期效果,同时降低了排烟温度,提高炉效、降低了厂用电率和煤耗。In view of Luan Power Generation 2 × 135 MW CFB boiler air preheater leakage rate exceeds bid badly problem, put forward the retrofit method by the air preheater leak examination and in pipe to reduce the air leakage rate. Modified to achieve the desired effect, and reduce the exhaust smoke temper- ature, increase boiler efficiency, reduce the service-power consumption rate and the coal consumption.
