Abstract
Abstract A waste incinerator for burning a variety of sludges, liquids and solid materials that can be reduced to a combustible liquid by exposure to heat. Such materials are fed into an incinerator and fall onto the uppermost of several superposed perforate beds. As the waste material is exposed to heat it becomes less viscous and slowly drips through the perforations of each bed to a subjacent bed where it is exposed to additional heat and ultimately gasified and burned.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
115 words
Apparatus for burning liquids, sludges, and solids that may be reduced to liquid form by the application of heat comprising a housing having an inlet opening for the charging of waste to be burned and an outlet opening for the exhaust of products of combustion therefrom, a plurality of perforate beds subjacent the inlet opening adapted to retain the combustible waste falling from the inlet opening, burner means laterally adjacent the upper surface of the perforate beds adapted to exhaust laterally to subject the liquid waste retained thereby to the heat of combustion, and a packed bed of refractory objects carried by the perforate beds of said apparatus that retain heat exhausting from the burner.
Claim 2
Dependent Claim
115 words
Apparatus for burning liquids, sludges, and solids that may be reduced to liquid form by the application of heat comprising a housing having an inlet opening for the charging of waste to be burned and an outlet opening for the exhaust of products of combustion therefrom, a plurality of perforate beds subjacent the inlet opening adapted to retain the combustible waste falling from the inlet opening, burner means laterally adjacent the upper surface of the perforate beds adapted to exhaust laterally to subject the liquid waste retained thereby to the heat of combustion, and a packed bed of refractory objects carried by the perforate beds of said apparatus that retain heat exhausting from the burner.
Claim 3
Dependent Claim
147 words
Apparatus for burning liquid waste and combustible material that may be reduced to liquid by the application of heat comprising a housing having a primary and a secondary combustion chamber in lateral juxtaposition, an inlet opening for charging waste material into the primary combustion chamber, an outlet opening for the exhaust of products of combustion from the secondary chamber, an exhaust stack connected to the outlet opening, an afterburner in the exhaust stack adapted to subject gases exhausting from the secondary chamber thereto, perforate baffle means lying vertically in said housing and adapted to separate the primary from the secondary combustion chambers, a plurality of spaced perforate beds lying horizontally in the primary chamber subjacent the loading opening, and burner means intermediate the perforate beds exhausting across the perforate beds and arranged to subject liquid waste falling from the inlet opening to the heat of combustion therefrom.
Claim 4
Dependent Claim
147 words
Apparatus for burning liquid waste and combustible material that may be reduced to liquid by the application of heat comprising a housing having a primary and a secondary combustion chamber in lateral juxtaposition, an inlet opening for charging waste material into the primary combustion chamber, an outlet opening for the exhaust of products of combustion from the secondary chamber, an exhaust stack connected to the outlet opening, an afterburner in the exhaust stack adapted to subject gases exhausting from the secondary chamber thereto, perforate baffle means lying vertically in said housing and adapted to separate the primary from the secondary combustion chambers, a plurality of spaced perforate beds lying horizontally in the primary chamber subjacent the loading opening, and burner means intermediate the perforate beds exhausting across the perforate beds and arranged to subject liquid waste falling from the inlet opening to the heat of combustion therefrom.
Claim 5
Dependent Claim
48 words
Apparatus for burning liquid waste as defined in claim 2 including feeding means that supplies waste material to the primary combustion chamber, a thermocouple in secondary combustion chamber, and means regulating the feeding means to the primary combustion chamber in response to the temperature detected by said thermocouple.
Claim 6
Dependent Claim
27 words
Apparatus for burning waste material as defined in claim 2 wherein horizontal perforate beds depend from the vertical baffle that separates the primary and secondary combustion chambers.
