Abstract
Abstract An incinerator having a primary burner for receiving waste to be burned and a secondary burning chamber and settling chamber through which the smoke and gasses from the primary burning chamber successively pass. A suction fan is provided at an outlet in the settling chamber to provide a draft and a heat retentive baffle member is positioned between the primary and secondary chambers in the path of the waste gasses and smoke to divide and preheat the gasses and smoke flowing from the primary chamber into the secondary chamber.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
201 words
A portable incinerator including: an elongated casing having means at one end for feeding combustible wastes therein and having suction means at the other end for discharging products of combustion into the atmosphere; a primary burning chamber at said one end of the casing having ignition means for initially igniting waste; a settling chamber, having a floor at said other end of the casing and having means for separating gasses and solid pArticles carried by said gasses, said settling chamber opening into said suction means; a secondary burning chamber having an inlet and outlet disposed between and communicating with both said first mentioned chambers; and heat retentive baffle means at the inlet and outlet of said secondary burning chamber for maintaining the latter in a heated condition when the incinerator is transported from site to site, the baffle means at the inlet of the secondary burning chamber including an upper, vertically disposed portion having a transverse upper edge extending above the secondary burning chamber and a lower, louvered portion confronting said secondary burning chamber so as to provide two paths of different length for the passage of the products of combustion from the primary burning chamber to the secondary burning chamber.
Claim 2
Dependent Claim
201 words
A portable incinerator including: an elongated casing having means at one end for feeding combustible wastes therein and having suction means at the other end for discharging products of combustion into the atmosphere; a primary burning chamber at said one end of the casing having ignition means for initially igniting waste; a settling chamber, having a floor at said other end of the casing and having means for separating gasses and solid pArticles carried by said gasses, said settling chamber opening into said suction means; a secondary burning chamber having an inlet and outlet disposed between and communicating with both said first mentioned chambers; and heat retentive baffle means at the inlet and outlet of said secondary burning chamber for maintaining the latter in a heated condition when the incinerator is transported from site to site, the baffle means at the inlet of the secondary burning chamber including an upper, vertically disposed portion having a transverse upper edge extending above the secondary burning chamber and a lower, louvered portion confronting said secondary burning chamber so as to provide two paths of different length for the passage of the products of combustion from the primary burning chamber to the secondary burning chamber.
Claim 3
Dependent Claim
53 words
Structure as defined in claim 1 wherein the baffle means at the outlet of the secondary burning chamber includes a plate located in the path of the products of combustion, and being angularly disposed for deflecting the products of combustion passing from the secondary burning chamber towards the floor of the setting chamber.
Claim 4
Dependent Claim
75 words
Structure as defined in claim 1 wherein the settling chamber has a discharge port spaced above the floor and a baffle disposed between said discharge port and floor in the path of the products of combustion, said baffle having a curved deflecting face for causing cyclonic movement of the products of combustion before the latter pass from the settling chamber so as to cause separation of gasses and solid particles in said products of combustion.
Claim 5
Dependent Claim
70 words
Structure as defined in claim 1 including a jacket extending from end to end of the casing in spaced relation to the latter, said jacket forming a passage, said passage being open adjacent said one end of the casing and communicating with the suction means at the other end of the casing so that cool air is drawn between said casing and said jacket when the suction means is operated.
Claim 6
Dependent Claim
61 words
Structure as defined in claim 4 wherein the suction means includes a housing mounted on the casing over the discharge port and communicating with the passage, and a blower in the housing arranged to discharge therefrom to atmosphere so that the products of combustion entering said housing are mixed with the air entering through the passage before being discharged to atmosphere.
Claim 7
Dependent Claim
18 words
Structure as defined in claim 1 wherein the heat retentive baffle means is formed of a refractory material.
Claim 8
Dependent Claim
13 words
Structure as defined in claim 6 wherein the refractory material is silicone carbide.
