摘要

大型汽轮机高中压合缸的中间轴封漏汽量一般大于设计值

对机组热耗率影响较大。对漏汽量的测量较难进行

对此

研究了进行漏汽测量的测点布置、测试方法、测试结果计算等。结果表明

1%的主蒸汽漏汽量可影响机组热耗率0.22%～0.26%。

Abstract

Taking mixed coal composed of lean coal and anthracitic coal commonly used in power plants of Shandong Province as coal sort to be tested

the burnaway of said mixed coal

as well as releasing behavior of SO2 and H2S gases along the furnace have been studied on onedimensional pulverized coal firing test stand. Test shows that the sulfur educing behavior is closely related to coal quality and burning behavior of each single coal sort and the mixed ratio of single coal sorts. Along with variation of the coal quality and the mixed ratio

concentration of SO2 to be basically between two single coal sorts

but the regularity of H2S educing to be comparatively complex.
