Thomas, D; Briggs, E C

A portable LP gas heater includes a combustion chamber the discharge end of which is open and unobstructed and the inlet end of which is defined by a rear head plate having a central primary air inlet into which projects, to a limited degree, a cylindrical fuel nozzle. The projected extremity of the nozzle which positions within the combustion chamber mounts a transversely disposed baffle which is parallel to and spaced preferably about one inch from the rear head plate. Fuel exits from and about the nozzle immediately adjacent and upstream of the baffle. The baffle has a size which permits it to be introduced to and removed from the combustion chamber by way of the primary air inlet. The rear head is further distinguished by a single group of apertures located adjacent its outer periphery in a substantially ring-like pattern. The outermost face of the rear head mounts, in addition to the nozzle bracket, a pair of fins arranged to receive and induce a smooth swirling movement of the primary air to and through its central inlet. The manner of application of the primary air induces a swirling high velocity flow thereof about the nozzle to pick up fuel immediately as it exits therefrom and immediately thereafter impact therewith upon the baffle, producing a substantial breakdown of the fuel and a violent turbulent reaction of the air, within which the fuel is thoroughly disseminated and moved immediately outward of the baffle.
