甲烷对煤粉着火的实验研究与模型计算

依据零值边界梯度着火理论,建立煤粉颗粒群与甲烷的混合着火模型。采用该模型对煤粉颗粒群与甲烷混合物在滴管炉中的着火孕育时间实验进行模拟,通过与实验结果的对比,表明该模型计算得到的结果与实验结果符合较好。 A ignition model of pulverized coal particles cofiring with methane is given by applying the zero grads boundary layer theory.This model is used for the predicting the ignition delay of pulverized coal particles cofiring with methane in a drop tube furnace and the calculation results of the model agree fare well with the results of the experiments
