由于普通集总渣层法模型无法反映气化炉中各参数的分布特性，将水煤浆气化炉仿真中运用的小室建模方法与集总渣层法模型相结合，形成一种新的小室渣层法气化炉模型，并使用该模型对shell气化炉进行仿真．将模型仿真得到的稳态与动态结果与已有文献数据及原有集总渣层法的仿真结果进行了对比和分析．结果表明：小室渣层法的仿真结果与文献数据相吻合，具有良好的可行性，且在参数分布变化仿真方面的性能优于传统的集总渣层法模型．

To solve the problem that conventional model of gasifier based on lumped slag layer method can't reflect the distributed-parameter characteristics in the gasifier, a new cell-slag model was built to cover the shortage of conventional model, which takes the advantage of both the lumped slag layer method and the cell method for simulation of coal slurry gasifiers. Using the new model, numerical simulation was made on a shell gasifier, of which the results obtained at both steady and dynamic state were analyzed and com- pared with corresponding literature data and the simulation results based on original lumped slag layer method. Results show that the simulation results by the cell-slag method agree well with corresponding literature data, proving the new method to be feasible and superior to conventional model in simulation of distributed-parameter characteristics.
