排烟热量损失是锅炉效率损失中最大的一项,国内大量电站锅炉由于设计、运行方面的原因存在排烟温度高的问题。就某厂二期工程锅炉排烟温度高的问题展开分析,并通过增加省煤器面积以及对空预器转向进行改造的方案,成功地使锅炉排烟温度下降近14℃,取得了较好的节能效果,为同类锅炉的改造提供了可借鉴的经验。 Exhaust heat loss is the largest loss of boiler efficiency, a large number of domestic power plant boiler due to the design, operation, there is the problem of high exhaust temperature. On the second phase of a factory boiler exhaust gas temperature analysis of the issue and by increasing the economizer area and the air preheater diverting program, the successful boiler exhaust temperature dropped nearly 14 ℃, and achieved good Of the energy-saving effect, for the transformation of similar boilers provides a reference experience.
