中文摘要：
以5种煤泥型煤为原料进行燃烧实验,研究煤泥型煤的燃烧特性及影响因素.结果表明,成型过程及黏结剂等对煤泥的燃烧性能基本无影响;煤泥型煤燃烧初期主要为挥发分的析出和燃烧,火焰旺盛火力强;型煤中后期燃烧为焦炭的燃烧,燃烧由型煤表面不断深入内部进行,氧气要扩散到焦炭表面会受到灰壳及其内部产生的挥发分和燃烧产物等扩散阻力.型煤挥发分越高,灰分越低,其燃烧速率越大,且易于燃尽.
英文摘要：
Five kinds of coal slime briquette were used for burning test to study the com- bustion characteristics and influencing factors. The experiments show that forming process and binder almost have no influence on the combustion characteristics of coal slime, the early stage of coal slime combustion was mainly the devolatilization and combustion of volatile, having vigorous flame and strong fire. The middle and late was the combustion of coke, from surface to interior, the oxygen would diffuse into the surface of coke by the resistance of gray shell, volatile and corn- bustion products from the interal. The briquette volatile is higher and the ash content is lower, the burning rate is greater, and easy to burn out.
