Abstract: The thermal gravimetric analysis of coal water mixture（CWM） prepared from industrial waste was carried out with thermal balance method.Compared its combustion characteristics with these of raw coal CWM.Tested the volatile initial precipitation temperature,ignition temperature,burnout temperature,burnout characteristic exponent（Cb） of these two CWM.The results show that,the first three exponents of industrial waste CWM are lower than those of raw coal CWM,while Cb is higher.That means the industrial waste CWM has better combustion characteristics.
