一、前言 煤粉——流化床复合燃烧是在同一炉膛中采用了煤粉燃烧和流化床燃烧两种燃烧方式。流化床燃烧方式可以燃烧劣质燃料,便于减少有害气体对大气的污染,受到国内外的普遍重视,它的主要问题是燃烧效率低,影响了它的发展;而煤粉燃烧则刚好相反,它有较高的燃烧效率,但是,在煤种适应性和减少污染方面不如流化床燃烧。复合燃烧 I. Introduction Pulverized coal - fluidized bed composite combustion in the same furnace with pulverized coal combustion and fluidized bed combustion two kinds of combustion. Fluidized bed combustion can burn low quality fuels and facilitate the reduction of harmful gas pollution to the atmosphere. It has received widespread attention both at home and abroad. The main problem is that the combustion efficiency is low, which affects its development. Pulverized coal combustion, on the contrary, Higher combustion efficiency, however, is not as good as fluidized bed combustion in terms of coal suitability and pollution reduction. Compound burning
