一、引言 循环流化床燃烧是最近十年来迅速发展起来的新型烧煤技术,它的煤种燃烧适应性好,可燃用劣质燃料;可以通过向炉内添加石灰石进行简廉的脱硫处理,为解决燃煤带来的二氧化硫大气污染和酸雨防治提供了可行的手段;氧化氮排放亦低。煤炭是我国的主要能源,目前我国燃煤技术比较落后,燃料利用效率低,污染严重,迅速开发 I. INTRODUCTION Circulating fluidized bed combustion is a new type of coal burning technology developed rapidly in recent ten years. It has good adaptability to coal combustion and can burn with inferior fuel. It can be used as a simple desulfurization treatment by adding limestone into the furnace. Solve the coal-fired sulfur dioxide caused by air pollution and acid rain control provides a viable means; nitrogen oxide emissions are also low. Coal is the main energy source in our country. At present, coal-fired technology in our country lags behind with low efficiency of fuel utilization, serious pollution and rapid development
