Статья: Reduced-Order Modeling of Pulverized Coal Staged Gasification: Influence of Primary and Secondary Fuel Proportion

The paper is concerned with the numerical simulation of the coal gasification process in an entrained flow of high-temperature air-steam mixture. Due to the high initial temperature and the process staging, it is possible to obtain an efficient gasification process. The study aims to examine the stationary conditions of staged gasification process by using a mathematical model based on one-dimensional heat and mass transfer equations with combined submodels to describe physicochemical transformations. The simulation makes it possible to determine the boundaries of the transition from the “single-stage” to the “two-stage” gasification conditions and identify the most promising ones.
