摘要
PURPOSE: A coal burner of pulverized coal combustion type without preheating is provided to burn the pulverized coal by generating the proper heat in initial ignition without preheating.;CONSTITUTION: A coal burner of pulverized coal combustion type without preheating comprises hydrogen and air injection ports(9,10), a pulverized coal injection port(7), an oxygen pipe, a nozzle, and a pulverized coal pipe. A hydrogen injection port connected to a hydrogen pipe(9a) is positioned to be vertical to the lower end of a burner. An air injection port connected to an air pipe(10a) is positioned to be vertical to the upper end of a burner. The pulverized coal injection port is connected to the pulverized coal pipe. The oxygen pipe is connected to an oxygen injection port(8) of the rear side. The nozzle exhausts the oxygen while swirling. The pulverized coal pipe discharges the pulverized coal while swirling the pulverized coal by a male-spiral protruded portion(11) or a fan.;COPYRIGHT KIPO 2010
