中文摘要: 研究了配煤比例变化对燃煤锅炉尾部受热面飞灰磨损的影响.对神木煤与优大同煤两个煤种的4种配煤比例(神木:大同,1:0,3:1,2:1,2:2)燃烧后所得灰样进行热态冲刷磨损试验,发现配煤中含灰量与磨损量呈非线性关系,即含灰量较大的煤掺入比例增加时,磨损量并不会相应增加.

中文关键词: 飞灰磨损动力配煤电厂锅炉

Abstract:This paper analyzes the impact of the variation of coal proportion on flying-ash erosion in heating surface at the rear of coal-fired boiler.By texting the erosion of the hot-state of the ash after burning the mixed coal of Shenmu coal and Datong coal in the 4 proportions of 1:0,3:1,2:1,2:2,it is found that the relation of ash rate to erosion rate is nonlinear,that is,the erosion rate cloes not increase with the increase of the proportion of the higher ash rate coal.

keywords: flying-ash erosion steam coal blending boiler in power plants
