东锅超临界“W”火焰锅炉燃烧调整试验研究

Combustion adjustment experimental investigation for DG super critical W-flame boiler

针对东方锅炉股份有限公司生产的超临界"W"型火焰锅炉,通过大量的现场燃烧调整试验研究,大幅度降低了水冷壁壁温差,提高了锅炉效率,全厂节约标煤量13 630 t/年,直接经济效益900万元/年以上。同时,每年可降低CO_2排放量3 4520 t/年、SO_2 1 480 t/年、粉尘量4 730 t/年,具有很好的经济效益和社会效益。本文研究成果可广泛应用于同类型锅炉的燃烧调整,对火电厂运行调整也具有指导意义。

Aiming at DG super critical W-flame boiler, through a lot of field combustion adjustment test research, we could reduce temperature difference of water wall tubes, and increased boiler efficiency to save standard coal 1 3630 t/y, achieve direct economic benefit of 900 million yuan a year, reduce discharge of CO2 34 520t/y, SO2 1 480 t/y and dust capacity 4 730 t/y, having good economic and social efficiency. The research could be widely applied to combustion adjusting of the same type boilers and also was useful for the operation adjustment of power plants.
