Incinerator for refuse in containers and method of incineration therefor

Claim 2

Apparatus by which refuse in an open-topped container can be completely incinerated without being removed from the container, said apparatus comprising: A. a receiver dish upon which the container can rest with its open top uppermost, said receiver dish being large enough to have marginal portions that extend beyond a container thereon for receiving material that falls down alongside the container; B. means defining a closed incineration chamber having at least one door through which the receiver dish with a container thereon can be moved into and out of the incineration chamber; C. liquid cooled supporting means in the interior of the incineration chamber upon which a receiver dish having a container thereon can rest and upon which the receiver dish is readily movable horizontally; D. burner means in said chamber comprising fuel nozzle means located and arranged to guide burning fuel substantially laterally against the side of a container in the chamber; E. means for blowing air downwardly into the open top of a container in the incineration chamber, the last mentioned means comprising (1) a downwardly opening air nozzle in an upper portion of the incineration chamber interior; and (2) means for forcing air through said nozzle at a rate to cause a substantial stream of air to be projected downwardly therefrom; F. said incineration chamber has a length to contain a substantially aligned plurality of receiver dishes, each with a container thereon, further characterized by: (1) said burner means comprising a plurality of fuel nozzles spaced from one another along the length of the chamber; (2) a plurality of air nozzles spaced from one another along the length of the chamber, and (3) said chamber having doors at both ends thereof to permit receiver dishes and the containers they carry to move through the chamber in one direction, entering the chamber at one end thereof and leaving it at its other end; G. means linking a plurality of receiver dishes with one another, chain-fashion, and means for advancing the linked receiver dishes stepwise into, through and out of the incineration chamber; and H. said liquid cooled supporting means comprises liquid cooled pipes fixed in substantially closely spaced relation and in a common horizontal plane, upon which receiver dishes can slide.

Claim 3

The apparatus of claim 1, further characterized by: said doors being arranged in sets at the ends of the incineration chamber, with a set of doors at each end of said chamber arranged to define an air lock in which one receiver dish and a container thereon can be held, said air locks thus preventing substantial loss of heat from the interior of the incineration chamber as containers are moved into and out of the chamber.

Claim 4

The apparatus of claim 1 wherein said means for forcing air through said nozzle is constructed and arranged to impart to such air a pressure higher than 0.5 kg/cm 2 G and to propel such air at a rate on the order of 0.1 to 0.5 m 3 per minute.

Claim 5

Apparatus by which refuse in an open-topped container can be completely incinerated without being removed from the container, said apparatus comprising: A. a receiver dish upon which the container can rest with its open top uppermost, said receiver dish being large enough to have marginal portions that extend beyond a container thereon for receiving material that falls down alongside the container; B. means defining a closed incineration chamber having at least one door through which the receiver dish with a container thereon can be moved into and out of the incineration chamber; C. liquid cooled supporting means in the interior of the incineration chamber upon which a receiver dish having a container thereon can rest and upon which the receiver dish is readily movable horizontally; D. burner means in said chamber comprising fuel nozzle means located and arranged to guide burning fuel substantially laterally against the side of a container in the chamber; E. means for blowing air downwardly into the open top of a container in the incineration chamber, the last mentioned means comprising (1) a downwardly opening air nozzle in an upper portion of the incineration chamber interior; and (2) means for forcing air through said nozzle at a rate to cause a substantial stream of air to be projected downwardly therefrom; F. said incineration chamber has a length to contain a substantially aligned plurality of receiver dishes, each with a container thereon, further characterized by: (1) said burner means comprising a plurality of fuel nozzles spaced from one another along the length of the chamber; (2) a plurality of air nozzles spaced from one another along the length of the chamber, and (3) said chamber having doors at both ends thereof to permit receiver dishes and the containers they carry to move through the chamber in one direction, entering the chamber at one end thereof and leaving it at its other end; G. means linking a plurality of receiver dishes with one another, chain-fashion, and means for advancing the linked receiver dishes stepwise into, through and out of the incineration chamber; and H. said liquid cooled supporting means comprises liquid cooled rollers arranged parallel to one another, transversely to the length of the incinerator, and in a common horizontal plane, and upon which receiver dishes can ride as they are moved through the incineration chamber.

Claim 6

Apparatus by which refuse in an open-topped container can be completely incinerated without being removed from the container, said apparatus comprising: A. a receiver dish upon which the container can rest with its open top uppermost, said receiver dish being large enough to have marginal portions that extend beyond a container thereon for receiving material that falls down alongside the container; B. means defining a closed incineration chamber having at least one door through which the receiver dish with a container thereon can be moved into and out of the incineration chamber; C. liquid cooled supporting means in the interior of the incineration chamber upon which a receiver dish having a container thereon can rest and upon which the receiver dish is readily movable horizontally; D. burner means in said chamber comprising fuel nozzle means located and arranged to guide burning fuel substantially laterally against the side of a container in the chamber; E. means for blowing air downwardly into the open top of a container in the incineration chamber, the last mentioned means comprising (1) a downwardly opening air nozzle in an upper portion of the incineration chamber interior; and (2) means for forcing air through said nozzle at a rate to cause a substantial stream of air to be projected downwardly therefrom; F. said incineration chamber has a length to contain a substantially aligned plurality of receiver dishes, each with a container thereon, further characterized by: (1) said burner means comprising a plurality of fuel nozzles spaced from one another along the length of the chamber; (2) a plurality of air nozzles spaced from one another along the length of the chamber, and (3) said chamber having doors at both ends thereof to permit receiver dishes and the containers they carry to move through the chamber in one direction, entering the chamber at one end thereof and leaving it at its other end; G. means linking a plurality of receiver dishes with one another, chain-fashion, and means for advancing the linked receiver dishes stepwise into, through and out of the incineration chamber; and H. said liquid cooled supporting means comprises liquid cooled rollers arranged parallel to one another, transversely to the length of the incinerator, and in a common horizontal plane, and upon which receiver dishes can ride as they are moved through the incineration chamber.
