Abstract
The gasification of coal dust in thermal power plants is a prospective technology for combining the production of electric power, heat, and chemical products. In this work, the method of calculating flow gasification, which takes into account the detailed diffusion and chemical kinetics of process has been proposed. To describe the combustion of a coal particle in a flow reactor for thermochemical conversion of solid fuel, the model of consecutive equilibrium states with stationary constraints has been suggested. According to the model of investigated system (fuel particle and gas surrounding), the process can be treated as a sequence of closed thermodynamic equilibrium subsystems, linked to each other by the stationary flows of matter and energy. A description of model and comparison of calculation results with experimental data have been presented.
