【Abstract】 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.更多还原
