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%. ER -
