Gasification of pulverized fuel in a filtration combustion reactor with a heat carrier counterflow

A stationary mathematical model is used to estimate the characteristics of gasification of pulverized fuel in a filtration combustion reactor with a heat carrier counterflow are estimated. The high efficiency of the gasification method under study is established. The movement of the heat carrier toward the flow of gaseous products makes it possible to recuperate a significant part of the thermal energy released, which has a significant effect on the temperature and composition of combustion products. It is shown that the gasification characteristics can be purposefully changed by varying three main parameters: air flow rate, steam flow rate, and heat carrier flow. As an example, the dependences of the main gasification characteristics (combustion temperature, product composition, and process efficiency) on control parameters are calculated. Calculations make it possible to estimate possible modes and select an optimal set of control parameters for gasification.
