摘要

针对茂名热电厂410t/h燃油锅炉改烧水煤浆进行了试验研究

结果表明:对锅炉进行改造后

全烧重油和水煤浆都能达到额定出力和预定的设计参数

热效率分别比设计效率提高了0.93%、1.45%

燃烧状况良好

飞灰和炉渣可燃物含量低

达到了长期连续运行的要求;与燃烧重油相比

燃烧水煤浆时SO2排放减少一半

NOx排放略有增高;燃油锅炉改烧水煤浆具有非常显著的经济效益和环保效益。

Abstract

Directing against retrofitting oil-fired 410 t/h boiler in Maoming Power Plant into coal-water slurry（CWS） fired one

a test study has been carried out. Results show that the rated output capacity and the prediccted design parameters of the retrofitted boiler can all be reached by wholly burning heavy oil or CWS

the thermal efficiecy can be enhanced 0.93% and 1.45% of the designed efficiency respectively. The situation of combustion is good

the combustible carbon content in ash and slag is low

the requirements for long-term continuous operation have been satisfied. Comparing with buring heavy oil

half of SO

emission can be reduced when buring CWS

but the NO

emission to be slightly enhanced. Extremely remarkable economic and environmental benefits can be obtained by retrofitting oil-fired boiler into CWS-fired one.
