Furnace apparatus

Abstract

Apparatus for collecting and disposing of refuse having a wheeled chassis carrying a hopper, shredder and fan for directing air and refuse to a cylindrical member preferably obliquely disposed with respect to the chassis. A hollow tube is disposed within the cylindrical member in generally co-axial relationship. The tube is provided with a plurality of apertures for directing flame therefrom against refuse within the interior of the cylindrical member. Washing apparatus is included to minimize contamination dispersal into the atmosphere. .Iadd.

What I claim as new and desire to secure by Letters Patent of the United States is: 
     
       1. .[.A mobile.]. .Iadd.An .Iaddend.apparatus for collecting and burning refuse comprising: a chassis .[.having wheels for movement between collection and and disposal points and.]. having thereon the following structures: a hopper disposed on said chassis for receivng refuse;   a shredder communicating with said hopper for reducing the size of the refuse received by said hopper to particles suitable for burning;   a first transfer means for receiving refuse conditioned by said shredder;   .[.a cylindrical member.]. .Iadd.an elongated hollow chamber .Iaddend.having a perforate skin for allowing passage of ash therethrough and having first and second ends, said first end communicating with said first transfer means for receiving said refuse;   means for urging at least some of said refuse through said .[.cylindrical member.]. .Iadd.chamber .Iaddend.to said second end;   a fan communicating with said .[.cylindrical member.]. .Iadd.chamber .Iaddend.for supplying air to the interior of said .[.cylindrical member;.]. .Iadd.chamber;.Iaddend.   a hollow tube disposed generally co-axially with respect to said .[.cylindrical member.]. .Iadd.chamber .Iaddend.and having a plurality of apertures disposed substantially uniformally about the circumference .[.of said apertures.]., said apertures being sized for burning a fuel;   a fuel supply and control means for supplying fuel to said hollow tube;   a liquid supply and a liquid spray means for wetting ash passing out of said .[.cylindrical member.]. .Iadd.chamber .Iaddend.through said perforate skin and said second end of said .[.cylindrical membr;.]. .Iadd.chamber;.Iaddend.   second transfer means for moving ash from said .[.cylindrical member;.]. .Iadd.chamber;.Iaddend.   an ash receiving means disposed in communication with said second transfer means;   a substantially closed housing mounted on said chassis and enclosing said .[.cylindrical member.]. .Iadd.chamber.Iaddend., liquid .[.spary.]. .Iadd.spray .Iaddend.means, second transfer means and at least a portion of said hollow tube;   a second fan in fluid communication with said substantially closed housing urging smoke from the area of said substantially closed housing; and   a purifying tank for washing the smoke conducted by said second fan and in fluid communication with said fan.     
     
     
       2. .[.An.]. .Iadd.The .Iaddend.apparatus as described in claim 1 wherein said .[.cylindrical member.]. .Iadd.chamber .Iaddend.is disposed with the axis thereof in oblique relationship to said chassis with said first end higher than said second end. 
     
     
       3. The apparatus as disclosed in claim 2 wherein said .[.cylndrical member.]. .Iadd.chamber .Iaddend.is rotatably mounted and includes drive means for rotating said .[.cylindrical member.]. .Iadd.chamber .Iaddend.about the axis thereof to urge refuse therethrough and said .[.cylindrical member.]. .Iadd.chamber .Iaddend.includes a helical generally planar member upstanding from the interior side of the surface thereof to urge the refuse axially along said .[.cylindrical member.]. .Iadd.chamber .Iaddend.when said .[.cylindrical member.]. .Iadd.chamber .Iaddend.is rotated by said drive means. 
     
     
       4. The apparatus as described in claim 3 wherein said fuel is gaseous and said control means includes valving regulating the flow thereof to said hollow tube. 
     
     
       5. The apparatus as described in claim 4 wherein said first and second transfer means comprises belts carried on rollers. 
     
     
       6. The apparatus as described in claim 5 further including a hydraulic pump and an auxiliary engine for driving said rollers carrying said transfer means and said hydraulic pump. 
     
     
       7. .[.A mobile.]. .Iadd.An .Iaddend.apparatus for collecting and burning refuse comprising: a chassis having thereon the following structures: a hopper disposed on said chassis for receiving refuse;   a shredder communicating with said hopper for reducing the size of the refuse received by said hopper to particles suitable for burning;   a first transfer means for receiving refuse conditioned by said shredder;   .[.a cylindrical member.]. .Iadd.an elongated hollow chamber .Iaddend.having a perforate skin for allowing passage of ash therethrough and having first and second ends, said first end communicating with said first transfer means for receiving said refuse;   means for urging at least some of said refuse through said .[.cylindrical member.]. .Iadd.chamber .Iaddend.to said second end;   a fan communicating with said cylindrical member for supplying air to the interior of said .[.cylindrical member;.]. .Iadd.chamber; .Iaddend.   a hollow tube disposed generally co-axially with respect to said .[.cylindrical member.]. .Iadd.chamber .Iaddend.and having a plurality of apertures disposed substantially uniformly about the circumference of said apertures, said apertures being sized for burning a fuel;   a fuel supply and control means for supplying fuel to said hollow tube;   a liquid supply and a liquid spray means for wetting ash passing out of said .[.cylindrical member.]. .Iadd.chamber .Iaddend.through said perforate skin and said second end of said .[.cylindrical member;.]. .Iadd.chamber;.Iaddend.   second transfer means for moving ash from said .[.cylindrical member;.]. .Iadd.chamber; .Iaddend.   an ash receiving means disposed in communication with said second transfer means;   a substantially closed housing mounted on said chassis and enclosing said .[.cylindrical member,.]. .Iadd.chamber, .Iaddend.liquid spray means, second transfer means and at least a portion of said hollow tube;   a second fan in fluid communication with said substantially closed housing urging smoke from the area of said substantially closed housing; and   a purifying tank for washing the smoke conducted .[.bby.]. .Iadd.by .Iaddend.said second fan and in fluid communication with said fan. .Iadd. 8. The apparatus as claimed in claim 1 wherein said chamber is cylindrical..Iaddend.
