摘　　要：利用热重分析仪对某电站用煤进行了热解和燃烧特性的热重实验研究。借助TG、DTG和DTA曲线,结合不同的燃烧特性判据,判别和比较了2个煤种的热解及燃烧性能,同时验证了不同判据的可靠性。Combustion properties and pyrolysis properties of coal used in power station have important effect on boiler design and operation. Experimental researches on the pyrolysis and combustion properties of two kinds of coal used in one power station are made using thermo - gravimetric apparatus. The pyrolysis characteristics and combustion characteristics of the two samples are compared with TG/DTG/DTA curves and some classical criteria. Meanwhile, reliability of these criteria are confirmed.
