Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
359 words
A garbage burning and melting apparatus comprising: (a) a modified blast furnace having channeled side walls and a sloping fire brick bottom floor; (b) a first chamber for mixing coal and garbage together; (c) a second chamber for holding and loading the mixed coal and garbage from said first chamber into said blast furnace for burning; (d) a hot air pump fluidly extending between said second chamber and said blast furnace for removing obnoxious odors from said second chamber and forcing a blast of hot air into said furnace at the low end of said blast furnace to produce the intense heat needed to burn the coal and garbage above the bottom floor; (e) means for cooling the side walls of said blast furnace with cool water entering an inlet pipe and exiting an outlet pipe in said blast furnace; (f) means for washing molten slag outside said blast furnace after the slag and lava leave through exit ports at the low sides of the bottom floor; (g) a conveyor located at the exit ports for conveying the molten slag and lava by-products away from said blast furnace for distribution; (h) means for filtering the exhausted gases from the top of said blast furnace to remove powdered ash therefrom in combination with scrubbers; (i) said first chamber includes a pair of sloping intersecting conduits in which one said conduit carries the coal therein and the other conduit carries the garbage therein to mixed together; (j) said second chamber includes a tank for holding the mixed coal and garbage and ram rod for loading the mixed coal and garbage into said blast furnace; and (k) said washing means includes a water reservoir having two inlet pipes and an outlet pipe, whereby the first inlet pipe is connected to a cold water supply, while the second inlet pipe is provided for carrying water that exits through the outlet pipe from said blast furnace back into said water reservoir; and a water pump fluidly connected between the outlet pipe of said water reservoir and the inlet pipe in said blast furnace so as to cool the side walls of said blast furnace.

Claim 3
Dependent Claim
65 words
A garbage burning and melting apparatus as recited in claim 1, wherein said filtering means includes: (a) a flue at the top of said blast furnace; (b) a plurality of spaced apart filters carried in said flue to remove various impurities from the gases exiting therefrom; and (c) a collector fluidly connected to each of said filters to remove the powdered ash from said filters.
