摘　　要：采用FG-DVC模型对水煤浆不同升温速率下的热重实验数据进行处理.结果表明,在挥发分析出温度范围内,表观活化能随升温速率升高而减小,DTG曲线峰值随升温速率升高而增大,符合实验数据的规律;模拟结果与实验曲线十分接近,且n=1情况下吻合情况最好,说明用FG-DVC模型描述水煤浆挥发分析出机理比较适合.The thermogravimetric data of coal water slurry at various heating rates were analyzed by using the FG DVC model in the temperature range of volatile matter release. Judging from the results, apparent activation energy decreased when heating rate increased and DTG peak value was on the contrary. The simulated results were very similar to the experimental data and the case n= 1 was the best fit. So FGDVC model is suitable for describing the process of volatile matter release from coal water slurry.
