| Abstract: | Based on the flowing characteristic of jet entrained gasifier (region model),the states are decomposed and the stochastic model of residence time distribution has been constructed.The simulation results of Markov chain are accordant with the experimental values,which shows that the process is stochastic and confirms that there are backflow and short circuit in the gasifier and flow pattern tends to complete mixing. |
