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