Abstract

In this paper the results obtained by the numerical method of modelling of Ekibastuz coal burning in BKZ-420 combustion chamber of Kazakhstan’s coal-fired Power Plant are presented. They are devoted to the numerical simulation of combustion processes in the furnace boiler BKZ-420. Boiler’s steam generating capacity 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 39 %, volatile – 24 %, humidity – 5 %, highest calorific value is 16 750 kJ/kg. In this research the main harmful gases distribution characteristics of the concentration of carbon oxides (CO and CO2), nitrogen dioxide (NO2), and oxygen O2 are shown.
