摘　　要：采用热天平在不同的升温速率下对１８种煤的最终挥发分产量的变化规律进行了研究．结果表明，最终挥发分产量主要取决于煤粒温度及升温速率，而受粒径的影响较小。文中给出了最终挥发分产量的计算公式．The varying law of the final volatile yield of 18 different coal types was studied at different heating rates by thermobalance. The results show that the final volatile yield mainly depends on the pulverized coal temperature and heating rate, and is insensitive to the coal particle diameter under experimental conditions. The calculation equations of the final volatile yield are given.
