MULTIPLE JET COAL BURNER Abstract of the Disclosure A burner of relatively small BTU rating embodying a mul- tiplicity of jets and particularly suited for burning pulverized coal in small air heater or furnace applications. The subject burner includes a housing having first inlet means formed at one end thereof and outlet means formed at the other end thereof. The first inlet means is connectable to a pipe means through which pulverized coal and primary air are fed from a suitable source thereof to the burner. The burner is further provided with second inlet means, the latter being formed in the burner housing so as to be located therein in close proximity to the aforesaid first inlet means. The second inlet means is connectable to a suitable source of secondary air from whence secondary air is fed to the burner. Both the first inlet means and the second inlet means are operatively connected in fluid flow relation with the outlet means of the burner whereby the primary air, the pulverized coal and the secondary air are all discharged from the burner at the outlet end thereof. A multiplicity of jets are embodied in the burner extending substan- tially the length thereof. Additionally, the burner includes spacing means operative for spacing the multiplicity of jets one from another in supported relation within the burner housing, and for defining a plurality of flow paths for the secondary air through the burner housing. Finally, there are provided mounting means oper- ative for cooperatively associating the burner with a small air heater, or small furnace, or other functionally similar piece of equipment. C780830
