【摘要】 试验研究了混合喷吹条件下诸因素对煤粉燃烧率的影响。试验及回归得出混合喷吹时不同因素对煤粉燃烧率影响的定量关系。试验表明,简单采用干粉混合的方法添加不可燃粉料恶化了煤粉的燃烧条件,随添加量增加影响加剧。添加粉料中,白云石粉对煤粉燃烧率影响最大。在添加粉料不大于10%时,喷吹烟煤粉仍可达到较好的燃烧率。更多还原

【Abstract】 The effect of some factors on the coal combustion efficiency is investigated in mixed injection condition. A quantitative relation is established by orthogonal design of laboratory test and analysis of the results with polynomial regression. It is clear that the coal combustion efficiency is significantly reduced if uncombustible material is dryly mixed with pulverized coal and the more the uncombustible material added the lower the coal combustion efficiency is. Among the added materials, the effect of dolomite fine is the worst. When the content of added uncombustible fine is less than 10% the combustion efficiency of bituminous coal powder mixed with added fine is still equal to or better than anthracite powder.更多还原
