利用热管式空气预热器提高锅炉效率

Improve boiler efficiency by thermodynamic duct air preheater

在６ｔ＇ｈ燃油锅炉尾部烟道上设置热管式空气预热器，使锅炉效率提高约３％，介绍了空预器的规格，形式及具体设置方案，对由于增加了空预器的阻力而不需增加风机压头的情况亦进行了核算．

A 6 t/h oil-fired boiler can be improved its efficiency by about 3% by setting a thermodynamic duct air.preheater on tie boiler's flue tail. The paper introduces the specification and form of such an air preheater, the concrete setting scheme, and the verification of no need of additional pressure head for air blower under increased resistance by air preheater as well.
