3D - MODELING OF PULVERIZED COAL COMBUSTION TAKING INTO ACCOUNT THE INFLUENCE OF THE LAYOUT OF THE COMBUSTION CHAMBER OF THE CHP 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. Based on the numerical solution of the system of equations of convective heat and mass transfer, taking into account the kinetics of chemical reactions, two-phase flow, nonlinear effects of convection and radiation heat transfer meth- ods and three-dimensional modeling, it is necessary to identify the aerodynamic characteristics throughout the volume of the combustion chamber, in its main sections and at the exit from it; to determine the influence of pulverized coal swirl flow in the combustion chamber of the boiler BKZ- 75 Shakhtinskaya СHP. The use of new geometric and physical models of the upgraded combustion chamber for the purpose of comparative analysis of the location and layout gorelochnyh devices.
