锅炉是能源消耗的大户,据2007年统计,锅炉用煤约占煤炭产量的85%。省煤器作为锅炉的主要节能部件,具有降低排烟温度,减少热损失,节省燃料,提高锅炉效率等功能。本文通过对2台220t/h锅炉不同类型省煤器热效率测试对比,了解传统型光管省煤器和H型鳍片管省煤器热效率情况,为工程设计人员和电厂技术改造提供参考。H型省煤器是把两片中间有圆弧的钢片对称地与光管焊接在一起形成鳍片(肋片或蝶片),正面形状
Boilers are major energy consumers. According to statistics in 2007, boiler coal accounts for about 85% of coal production. Economizer as the main energy-saving components of the boiler, with lower exhaust gas temperature, reduce heat loss, save fuel, improve boiler efficiency and other functions. This article compares the thermal efficiency of two economizers of different types of 220t / h boilers to understand the thermal efficiency of the economizer of traditional light pipe economizer and H-fin tube economizer, and provides references for engineering designers and power plant technological transformation. H-type economizer is the middle of two pieces of steel arc welded symmetrically with the light pipe to form a fin (fins or fins), the front shape
