PLASMA-CHEMICAL ACTIVATION OF FLAME COMBUSTION IN THE FURNACE OF A PULVERIZED COAL FIRED BOILER

Abstract

Results of comparative numerical calculations of conventional combustion of coal and combustion of plasma-chemically activated in plasma-fuel systems coal in a furnace are presented. The calculations were fulfilled using two computer codes. The first one is one-dimensional Plasma-Coal code considering detail kinetics of thermochemical conversions of fuel in two-phase flow with plasma source and the second one is Cinar ICE code considering furnace geometry, flow turbulence, radiative heat transfer and combustion of coal particles by the fast chemistry model. Perspective of plasma-fuel systems to activate coal combustion and to improve ecology and economical indexes of thermal power plants is demonstrated.
