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.
