PULVERIZED COAL BURNER FOR MINIMIZING NITROGEN OXIDE

摘要

PURPOSE: A pulverized coal burner stabilizes ignition and combustion responding to diverse load and hinders nitrogen oxide from generating. CONSTITUTION: A pulverized coal burner comprises a fixed density distributor(52), a variable density distributor(54) and a deflecting plate(64). The fixed distributor(52) defines a supplying passage of dust coal. The variable density distributor(54) controls the supplying amount of the dust coal by controlling air for transferring. The deflecting plate(64) gives directionality to dust coal injected. The pulverized coal burner makes possible the change of flowing passage of air for transferring in a nozzle so as to stabilize ignition and combustion responding to diverse load and hinder the generation of nitrogen oxide.
