Abstract
Abstract An incinerator is disclosed wherein the firebox has three openings, one being located higher than the other two, and wherein a conduit is provided to conduct gases exhausted therefrom to preferably the lowest one of the openings. Within the conduit is provided a venturi pump through whose throat is pumped air so that the venturi may draw the exhaust gases through the conduit, mixing the gases with the air and discharging the mixture into the firebox. Finally, the gases are exhausted from the remaining opening, relatively free of smoke or hydrocarbons. Preferably, the recirculation unit that includes the conduit and venturi pump is removeable so that any steel container may be used as a firebox.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
155 words
A smokeless incinerator comprising a fire box with first and second openings and forming exhaust gases when a fire is therein, first means for conducting substantially all of the exhaust gases exiting from said first opening back into said fire box, second means for allowing air to be mixed with the exhaust gases while in said first means at a temperature to allow further burning of the exhaust gases, and said second opening being spaced from said first opening for allowing the combustion products to pass out into the atmosphere, said first opening being located higher than said second opening and the point where the exhaust gases are returned to the fire box, said second opening being further disposed near the point where the exhaust gases are returned to the fire box, and said first means including a pipe section disposed within said fire box to direct the gases passing therethrough toward said first opening.
Claim 2
Dependent Claim
155 words
A smokeless incinerator comprising a fire box with first and second openings and forming exhaust gases when a fire is therein, first means for conducting substantially all of the exhaust gases exiting from said first opening back into said fire box, second means for allowing air to be mixed with the exhaust gases while in said first means at a temperature to allow further burning of the exhaust gases, and said second opening being spaced from said first opening for allowing the combustion products to pass out into the atmosphere, said first opening being located higher than said second opening and the point where the exhaust gases are returned to the fire box, said second opening being further disposed near the point where the exhaust gases are returned to the fire box, and said first means including a pipe section disposed within said fire box to direct the gases passing therethrough toward said first opening.
Claim 3
Dependent Claim
239 words
A smokeless incinerator comprising a fire box with first and second openings and forming exhaust gases when a fire is therein, first means for conducting substantially all of the exhaust gases exiting from said first openIng back into said fire box, second means for allowing air to be mixed with the exhaust gases while in said first means at a temperature to allow further burning of the exhaust gases, said second opening being spaced from said first opening for allowing the combustion products to pass out into the atmosphere, said second means including a nozzle for accelerating air to a relatively high velocity and a fan for supplying the air to said nozzle, said first means including a pipe through which said exhaust gases pass, said nozzle being disposed within said pipe to direct the air in the direction to cause the exhaust gases to enter said fire box, said second means including another opening in said first means located between said fire box and said nozzle to cause further combustion of the exhaust gases, said first opening being located higher than said second opening and the point where the exhaust gases are returned to the fire box, said second opening being disposed near the point where the exhaust gases are returned to the fire box, and said first means includes a pipe section disposed within said fire box to direct the gases passing therethrough toward said first opening.
Claim 4
Dependent Claim
239 words
A smokeless incinerator comprising a fire box with first and second openings and forming exhaust gases when a fire is therein, first means for conducting substantially all of the exhaust gases exiting from said first openIng back into said fire box, second means for allowing air to be mixed with the exhaust gases while in said first means at a temperature to allow further burning of the exhaust gases, said second opening being spaced from said first opening for allowing the combustion products to pass out into the atmosphere, said second means including a nozzle for accelerating air to a relatively high velocity and a fan for supplying the air to said nozzle, said first means including a pipe through which said exhaust gases pass, said nozzle being disposed within said pipe to direct the air in the direction to cause the exhaust gases to enter said fire box, said second means including another opening in said first means located between said fire box and said nozzle to cause further combustion of the exhaust gases, said first opening being located higher than said second opening and the point where the exhaust gases are returned to the fire box, said second opening being disposed near the point where the exhaust gases are returned to the fire box, and said first means includes a pipe section disposed within said fire box to direct the gases passing therethrough toward said first opening.
Claim 5
Dependent Claim
81 words
The incinerator of claim 2 wherein said fire box is elongated with said first opening formed in the roof thereof at one end and another first opening formed in the roof at the other end, said second opening is formed in one of the longer sides at the center thereof, said first means conducts the exhaust gases therein through said second opening near the bottom of the opening, leaving the combustion products to discharge through the top of the second opening.
