| Abstract: | Combustion of a pulverized coal torch has been numerically simulated on the basis of the equations of multicomponent turbulent
two-phase flows. The results of three-dimensional simulation of conventional and plasma activated coal combustion in a furnace
are presented. Computer code Cinar ICE was verified at coal combustion in the experimental furnace with thermal power of 3
MW that was equipped with plasma-fuel system. Operation of the furnace has been studied at the conventional combustion mode
and with plasma activation of coal combustion. Influence of plasma activation of combustion on thermotechnical characteristics
of the torch and decrease of carbon loss and nitrogen oxides concentration at the furnace outlet has been revealed. |
