Abstract
A portable gas-fired forced-draft heater has a burner assembly mounted in a tube coupled to the intake port of a motor-driven blower. The burner operates in a stream of high velocity air which flows past the burner to the blower. The burner includes shrouds which cooperate with a fuel and air mixing nozzle to enable fuel to be burned efficiently and reliably over a wide range of fuel flow rates to the burner. A flame stabilization surface is spaced appropriately from the nozzle to enable reliable ignition of the fuel-air mixture. A controlled portion of the warm gases passing through the blower is routed to a receptacle for a fuel container to maintain pressure in the container as the preferably liquefied gas fuel is consumed during operation of the heater.
