ABSTRACT:
A burner assembly for gaseous fuels having an outer housing, a blower and a unitized combustion cartridge. The combustion cartridge comprises an elongated cylinder having a flame holder at a downstream end thereof. The flame holder is provided with a plurality of spatially disposed diffusion plates attached to the cylindrical body of the combustion cartridge such that the center lines of the diffusion plates extend radially and perpendicularly from the cylindrical body. Each plate extends from the cylindrical body at an acute positive angle from the plane of their center lines. A plurality of orifices are disposed in the cylindrical body substantially adjacent the flame holder and a portion of the orifices communicate with orifice extender tubes so that gaseous fuel can be distributed over the upstream surface of the flame holder. The blower, which is pivotally connected to the housing so as to be selectively movable to permit access to the combustion cartridge, impels combustion air around the outside of the cylindrical body of the combustion cartridge, through interstices of the diffusion plates and into a combustion chamber where it is ignited with the gaseous fuels. The angular of disposition of the diffusion plates imparts a swirling motion to the flame, thus assuring efficient and complete combustion.
