The study of combustion processes of coal dust taking into account the inclination angle of vortex burners

Abstract

The study aims to examine thermal processes, caused by burning of pulverized coal in the combustion chamber of an industrial boiler existing CHP. It is necessary to receive new results of theoretical research, mathematical and computer modeling of processes of a turbulent heatmass transfer when burning coal-dust fuel in the furnace chambers of a copper of BKZ-75. On the basis of the numerical decision of system of the equations of a convective heatmass transfer, taking into account kinetics of chemical reactions, two-staging of a current, nonlinear effects of convective and radiation heat exchange and methods of three-dimensional modeling, it is necessary to reveal concentration characteristics on all volume of the furnace camera, in its main sections and at the exit from it; definition of influence to twist of a coal-dust stream in the furnace chamberof the boiler BKZ-75CHP Shakhtinskaya combined heat and power plant.
