Effects of end temperature and 其技术经济优势已经成为最具竞争力的燃煤 CO2 heating rate on the weight loss and gas releasing characteristics 减排技术之一，其燃烧特性和SO /NO 等污染物排 2 x of coal under CO2 atmosphere were analyzed. Results show 放特性已引起学术界和技术界的广泛关注[1-10] 。CO2 that effects of CO2 on the pyrolysis characteristics take place 取代N 进行燃烧对煤燃烧过程的影响一般表现在3 2 mainly in the high temperature zone, acting as the inhibition of 个方面：1）CO2 的热物性与N2 不同，CO2 相对N2 carbonate in coal from decomposing and the gasification of 具有更高的摩尔比热容、更大的气体密度和更高的
