ABSTRACT:
A burner for a gas dryer is made up of a mixing tube having an open end for admission of gas fuel into the mixing tube. At least one other opening proximate to the open end serves to admit air into the mixing tube for mixing the air and the gas fuel. A burner head is located at an end of the mixing tube opposite the open end for allowing a mix of gas fuel and air to be discharged and be ignited into a flame. A baffle is attached to the burner at the base of the burner head and extends radially outward therefrom to prevent disruption of combustion of the gas fuel and air mixture as a result of secondary air being drawn outside and along the length of the mixing tube from the open end thereof toward the burner head. An air heater assembly for gas dryer includes combustion chamber having an air inlet and an air outlet for allowing air to flow therethrough and be heated for being passed over clothes to be dried in a drum of a dryer. The aforementioned burner is employed in the air heater assembly within the combustion chamber.
