In this paper the results obtained by the numerical method of modeling of Ekibastuz coal burning in BKZ–420 combustion chamber of Kazakhstan Power Plant are presented. They are devoted to the numerical simulation of combustion processes in the furnace boiler BKZ–420. Boiler’s steam generates capacity equal 420 T\h. Boiler has six vertical pulverized coal burners arranged in two levels with three burners on the front wall of the boiler. High ash, low–grade coal from Ekibastuz burned in the furnace. Its ash content is 40%, volatile – 24%, humidity–5%, highest calorific value is 16750 kJ\kg. Milling dispersity of coal was equal to R90 = 15%.It was shown in this research that the most intense burning is observed in the central part of the chamber where the flow temperature reaches about 980 °C and it is seen that the temperature reaches a peak in the cross sections of the burners location. The combustion reaction there occurs more intensively.
