Abstract

Invention herewith described refers to the equipment for the combustion of pulverized coal that includes furnace (5) with four water-cooled walls (6). Numerous nozzle (1) peaks for the spray rich with fuel of primary air and coal, numerous nozzle (2) peaks for the current poor fuel primary air and coal, and numerous nozzle (3) peaks for the secondary air are arranged on the water-cooled walls (6) of the furnace (5) to form a set of burners (7). Numerous nozzle (4) peaks for the air that goes over the fire are arranged at each corner of the furnace (5) or on all water cooled walls (6). The nozzle (4) peak for the air that goes over the fire is situated above the burner (7). The included angle between the central line of the nozzle (3) peak for secondary air and its water-cooled wall (6) with the flame ball is in the range of 54 to 127 degrees.
