Energy efficient high static pressure fluid fuel burner

摘要: A gun-type fluid fuel burner having a blast tube with dispensing nozzle therein includes blower housing scroll side wall and opposite end walls. The has an upwardly facing air discharge opening which communicates the tube, one of walls inlet therein. squirrel cage wheel diameter more than twice its width is mounted for rotation in directly driven by two pole single phase alternating current motor on walls, drawing through input discharging under pressure opening. damper plate movement between open position closing opening, being moved to response from returning closed influence biasing force.
