Musto, R L

A burner of relatively small BTU rating is disclosed that is comprised of a multiplicity 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 where 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 ly and outwad in the shaft are sucked do pyrolysis chamber where they are covered bye chosen metal dihalide vapor is ionized by ; the total economic market potential is 64.4% of the technical potential, or 2072.4 MW, equivalent to 83,621 BPDE; and the lack of an operating history-detailing system reliability, safety, and operating costs-iment and test components; technology testing; analytmperature fatigue stren obtained.
