NUMERICAL SIMULATION PARAVIEW PULVERIZED COAL COMBUSTION PROCESS IN THE COMBUSTION CHAMBER BKZ 420

Abstract

This work is devoted to the description of the processes happening at combustion of coal-dust fuel in a fire chamber of a copper of burning of BKZ-420. Researches are directed to in- creases in efficiency of development of energy, the solution of environmental problems, preparation of new boilers. Similar measures will provide decrease in the deviations which are thrown out envi- ronment, and increase of the main indicators of thermal power plant. A main objective of work is numerical research of process of burning of coal-dust fuel in the combustion chamber. On the basis of the numerical decision of system of the equations of a convective heatmass transfer it is necessary to reveal thermal characteristics, aerodynamic characteristics of the combustion chamber, to investi- gate a structure, types and furnace plant of a boiler. During research the three-dimensional processes happening in a boiler at the heart of which are used Navier-Stokes's equation are used. Using geometrical these models of the BKZ-420 combustion chamber, are received 2D - diagrams by means of the Paraview program. By means of the computing FLOREAN program it is processed and are received a type of the chart base of numerical data of the combustion chamber of a boiler BKZ-420
