Title
COMPUTATIONAL STUDY OF THE OXYGEN COMBUSTION AND GASIFICATION OF PULVERIZED COAL FUEL PROCESSES AT POWER GENERATING FACILITIES OF DIFFERENT CAPACITIES
Abstract
This paper presents a numerical study of the combustion and gasification processes of pulverized coal fuel in the O2-CO2-H2O medium as applied to power generating facilities of different capacities with different types of burners. The proposed integrated mathematical model has been tested based on the data of experimental oxygen combustion and gasification of coal in the flow. The following three facilities have been considered: a test bench with a vortex burner of 2.5 MW capacity, an industrial BKZ 500-140-1 boiler of 400 MW capacity with direct-injection burners and a direct-injection gas generator with the capacity of about 150 kW. The dependence of physical and chemical processes on the operating parameters of the equipment (gas composition of the blast, oxygen concentration in the blast, oxygen excess ratio, flue gas recirculation) has been established.
