摘　　要：利用热分析仪和自行设计的实验台研究了生物质型煤的燃烧特性.结果表明:无烟煤生物质型煤中生物质分解释放速率快于烟煤生物质型煤,且无烟煤生物质型煤出现两个放热峰,分别为生物质分解、挥发分燃烧和固定碳分解所致,而烟煤生物质型煤仅一个放热峰.原料煤煤种和炉膛温度对生物质型煤的燃烧特性有明显影响,烟煤型煤燃烧特性优于无烟煤型煤;炉膛温度越高,生物质型煤燃烧失重率越大.The combustion of bio-briquette is studied by thermal analysis and self-designing testing system. The result indicated that the combustion speed of biomass in bituminous briquette is rapider than anthracite＇s, there are two exothermic peaks in bituminous briquette combustion, they were resulted by decompound of biomass,combustion of volatile matter and combustion of char, the anthracite bio-briquette have only one exothermic peak. It is revealed that the rank of raw coal and combustion temperature can effect the bio-briquette combustion characters, the combustion characters of bituminous coal is better than anthracite＇ s; the TG rate is greater with the combustion temperature.
