Abstract: In this study, the results obtained by the numerical method modeling of Ekibastuz coal burning in BKZ-420 combustion chamber of Kazakhstan Power Plant. There are devoted to the numerical simulation of the furnace boiler BKZ-420, its steam generating capacity equal 420 T h-1. Boiler has 6 vortical pulverized coal burners arranged in 2 levels with three burners on the front wall of the boiler. Burned in the furnace high ash, low-grade coal from Ekibastuz, its ash content 40%, volatile 24%, humidity 5%, highest calorific value 16750 kJ kg-1. Milling dispersity of coal was equal to R90 = 15%.
