Abstract
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 hydro-dynamics, heat and mass transfer and combustion of fuels in the volume of furnace devices were applied used. Cal-culations were performed for two regimes of pulverized coal combustion: the traditional one and using plasma activa-tion of coal combustion. It is shown that the use of plasma-fuel systems (PFS) allows optimization of the coal com-bustion process in the combustion chamber. Three-dimensional modeling of a pulverized coal furnace equipped with a PFS allows one to determine the optimal PFS layout on boilers of thermal power plants.
