ABSTRACT:
A unitary airflow diffuser for use with a forced-air space heater has a plurality of spurs radially extending from a hub. The spurs include one or more vanes for deflecting the airflow generated by fan blades within the space heater. A nozzle assembly is secured through an aperture in the hub of the diffuser for supplying fuel within a combustion chamber. Brackets can be provided for securing an igniter and a sensor to the airflow diffuser. Mounting tabs are provided on each vane to secure the airflow diffuser to a mounting plate disposed at the input of the combustion chamber. The nozzle ejects the fuel through a central aperture in the mounting plate into the combustion chamber. The mounting plate can have secondary apertures through which air can be diverted, and vanes can be provided on the mounting plates to direct air through the secondary apertures. The deflected air ensures that the fuel swirls around the nozzle and igniter and also serves as auxiliary combustion air with the result that a uniform, clean burning flame is realized.
