摘　　要：采用热重分析仪,对3种单煤以及不同掺混比(质量比)下两两掺混的混煤进行了热重分析实验。根据实验结果,对不同掺混比混煤的着火温度、可燃特性、稳燃特性、燃尽特性及综合燃烧特性等进行了探讨。按一定比例掺混,可有效改善燃煤的燃烧特性。The experiments of three kinds of single coals and their binary blends with different mixing ratios （mass ratio） are performed by thermo-gravimetric analyzer. According the experimental results, the ignition temperature, combustibility, stable combustion characteristics, burn-out characteristics and comprehensive combustion characteristics of the blended coals with different mixing ratios are discussed. The combustion characteristics of coals are improved effectively by mixing them in suitable proportions.
