白杨河电厂230t/h锅炉燃用水煤浆工业试验

Industrial Test for Burning Water-coal Slurry in 230 t／h Boiler of Baiyanghe Power Plant

介绍我国第 1 台 230 t ／h 燃油电站锅炉改烧水煤浆的工程改造、引进水煤浆燃烧器存在的问题。燃烧器改造后，通过配风、水煤浆喷嘴雾化汽压、不同负荷和煤种水煤浆的工业试验表明，燃烧效率达 98．5％ 以上；燃用水煤浆时的负荷可在 40％～100％ 时稳定燃烧。说明水煤浆是一种有效的代油燃料。

：This paper introduces the problems existing in the conversion retrofit of the first 230 t／h oil-fired boiler to water-coal slurry-fired in China and the application of water-coal slurry burners．After retrofitting of burners，the results of the industrial tests in air distribution，atomizing steam pressures of water-coal slurry with different coals showed that the combustion efficiency of boiler reached more than 98 5％，the boilet，when burning water-coal slurry，could operate stably at 40％～100％ loads．It is illustrated that water-coal slurry is an effective substitute fuel for oil．
