摘　　要：针对居民无烟煤、兰炭燃烧存在的难点燃、易断火、不耐烧等问题,通过热重燃烧试验,分析了兰炭、无烟煤、兰炭和无烟煤混合型煤的燃烧特性,利用民用煤燃烧试验装置进行民用洁净煤燃烧烟气污染物检测。结果表明,兰炭着火温度为449℃,无烟煤着火温度为504℃,兰炭的燃烧失重和失重速率均高于无烟煤,表明兰炭比无烟煤易点燃、燃烧持续时间短,混合型煤能够兼顾二者的燃烧特性,建议在型煤加工过程中采用无烟煤与兰炭混合原料成型。3种产品燃烧排放烟气中颗粒物质量浓度均低于30 mg/m3,烟气成分中SO2质量浓度均低于40 mg/m3,NOx质量浓度均低于140 mg/m3,林格曼黑度为0级,达到国家标准的限值要求。兰炭、无烟煤、兰炭和无烟煤混合型煤是农村居民燃煤的理想清洁燃料。In view of the problem of difficult to ignite, easy to break fire and less resistance of fire in combustion process of civil anthracite and semi-coke, the combustion and emission characteristics of semi-coke, anthracite and mixing briquette were studied through combustion test device. Results show the ignition temperature of semi-coke and anthracite are 449℃ and 504 ℃ , respectively. The burning weight loss and mass loss rate of semi-coke are higher than that of anthracite,illustrating that semi-coke presentes low ignition temperature and fast combustion rate compared with anthracite, and mixed briquette can take account of the combustion characteristics of semi-coke and anthra- cite. The mixture of semi-coke and anthracite is suggested to be the raw material for briquette. The particle concentration of three samples are lower than 30 mg/m^3 , content of SO2 and NOx are lower than 40 mg/m^3 and lower than 140 mg/m^3 , and the ringelmann blackness is grade 0. The test result is in conformity with national standards indicating semi-coke, anthracite and briquette would be the ideal civil clean fuel.
