Abstract

An incinerator for burning waste material employs an additional grate on which waste material is burned, thereby producing a layer of heated ashes and coke. The smoke and gases produced by the burning waste material are caused to be passed downwardly through this very hot layer of coke, thereby raising the temperature of the waste gases and burning off noxious pollutants entrained therein. The invention also provides a series of burning stations with adjacent ones burning in opposite directions; i.e., upwardly and downwardly. All waste gases and smoke produced by the burning waste material will pass sequentially through the series of burning stations, all of which will have a layer of hot coke, before being exhausted to the atmosphere. Fresh air blowers, fans, burners, and baffles are employed to cause the burning of the waste material in the additional station to be in a downward direction and to cause the waste gases produced in preceding stations to pass downwardly through the heated coke layer in the additional burning station. Air-injection tubes are used to provide air to the layers of waste material to aid in the combustion thereof.

Claims21

Dependent claims

An incinerator for burning waste material which, when burned, produces gases within which pollutants are entrained and which waste material, when burned, becomes a burning coke, said incinerator comprising:

at least one combustion chamber;
at least two burning stations in substantial side-by-side relation located in said at least one combustion chamber and comprising grate means for receiving and retaining material including waste material for burning thereon;
inlet means for the reception of waste material into said at least one combustion chamber for disposition on said grate means of said burning stations;
means for burning waste material disposed on said grate means of said burning stations;
said burning means including means for conducting air to and through the burning waste material on said grate means of said burning stations and means for directing the flames and gases from the material burning on said grate means of one of said burning stations to the material burning on the grate means of the other of said burning stations;
said conducting means also comprising means for conducting gases from the material burning on said grate means to and through the burning material on said grate means of said other of said burning stations;
said conducting means thereby constituting combustion aiding means for substantially increasing the temperature in the burning material on said grate means of said other of said burning stations to burn off pollutants entrained in and to thereby clean the gases;
and
conduit means for passing the gases which have been conducted through the burning material on said grate means of said other burning station to the atmosphere.
