Abstract
Abstract An incinerator comprising a primary combustion chamber having a combustion gas outlet communicating with a secondary combustion chamber, an exhaust outlet from said secondary combustion chamber, burner means positioned to provide both heat of combustion to said primary combustion chamber and auxiliary heat in the vicinity of the gas outlet of said primary combustion chamber such that combustion gasses passing from the primary combustion chamber through said gas outlet must pass through auxiliary heat, an air supply to said primary combustion chamber and a secondary air supply in the said secondary combustion chamber. Combustion of gasses escaping from the primary combustion chamber is completed by compressing the gasses into a highly concentrated form and ramming them under pressure into the secondary combustion chamber for burning. Advantageously, the air supply to the secondary combustion chamber is opposite to the entering concentrated gasses so that a reverse airflow is provided.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
An incinerator comprising a primary combustion chamber, a secondary combustion chamber, said primary combustion chamber having a combustion gas outlet communicating with said secondary combustion chamber, an exhaust outlet from said secondary combustion chamber, burner means positioned to provide both heat of combustion to said primary combustion chamber and auxiliary heat in the vicinity of the gas outlet of said primary combustion chamber such that combustion gasses passing from the primary combustion chamber through said gas outlet must pass through said auxiliary heat, an air supply to said primary combustion chamber and a secondary air supply in the said secondary combustion chamber positioned to provide a reversed airflow into said secondary combustion chambeR.
Claim 2
Dependent Claim
113 words
An incinerator comprising a primary combustion chamber, a secondary combustion chamber, said primary combustion chamber having a combustion gas outlet communicating with said secondary combustion chamber, an exhaust outlet from said secondary combustion chamber, burner means positioned to provide both heat of combustion to said primary combustion chamber and auxiliary heat in the vicinity of the gas outlet of said primary combustion chamber such that combustion gasses passing from the primary combustion chamber through said gas outlet must pass through said auxiliary heat, an air supply to said primary combustion chamber and a secondary air supply in the said secondary combustion chamber positioned to provide a reversed airflow into said secondary combustion chambeR.
Claim 3
Dependent Claim
15 words
The incinerator of claim 1 wherein a grate is provided in the primary combustion chamber.
Claim 4
Dependent Claim
13 words

Claim 5
Dependent Claim
20 words
The incinerator of claim 3 wherein the blower means is positioned to blow air up through said perforated refractory plate.
Claim 6
Dependent Claim
168 words
An incinerator comprising a primary combustion chamber, a secondary combustion chamber, said primary combustion chamber having a combustion gas outlet communicating with said secondary combustion chamber, an exhaust outlet from said secondary combustion chamber, burner means positioned to provide both heat of combustion to said primary combustion chamber and auxiliary heat in the vicinity of the gas outlet of said primary combustion chamber such that combustion gasses passing from the primary combustion chamber through said gas outlet must pass through said auxiliary heat, an air supply to said primary combustion chamber and a secondary air supply in said secondary combustion chamber positioned to provide a reversed airflow into said secondary combustion chamber, a passage way connecting the combustion gas outlet of the primary combustion chamber and the inlet of the secondary combustion chamber, said passage way being provided with means for compressing the heated combustion gasses passing through the said passage way into the secondary combustion chamber, said air supply to the primary combustion chamber including blower means.
