Plasma ignition of solid fuels at thermal power plants. Part 2. 3D modeling of the furnace of a pulverized coal boiler

This paper presents calculation results on plasma ignition and combustion of coal in the furnace of the PK-39-II boiler at Reftinskaya SDPP. For mathematical modeling of coal combustion in the boiler furnace, a three-dimensional mathematical model Cinar ICE and a software package for physical modeling and calculation of hydrodynamics, heat and mass transfer and combustion of fuels in the volume of furnaces were applied. Calculations were performed for two regimes of pulverized coal combustion: the traditional one and using plasma activation of coal combustion. It is shown that the use of plasma-fuel systems (PFS) allows the optimization of the coal combustion process in the combustion chamber. Three-dimensional modeling of a pulverized coal furnace equipped with a PTS allows one to determine the optimal PTS layout on boilers of thermal power plants.
