Abstract
Abstract An incinerator, especially for burning waste material with a device for pfying flue gases derived from a combustion chamber for burning the waste material. In the combustion chamber or adjacent thereto, discharge openings of conduit means are provided for conveying fresh air thereto. The device for purifying the flue gases comprises a filter of high heat-resistant material which is interposed between the combustion chamber and a flue.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
86 words
An incinerator plant with a flue, especially for burning waste materials, which comprises combustion means including a combustion chamber for receiving and burning waste materials, conduit means associated with said combustion chamber for conveying fresh air therethrough, and purifying means for purifying flue gases derived from the combustion of waste materials, said purifying means including filter means of high heat resistant material in said combustion chamber so that deposited particles themselves form a solid filter layer and interposed directly between said combustion chamber and said flue.
Claim 2
Dependent Claim
86 words
An incinerator plant with a flue, especially for burning waste materials, which comprises combustion means including a combustion chamber for receiving and burning waste materials, conduit means associated with said combustion chamber for conveying fresh air therethrough, and purifying means for purifying flue gases derived from the combustion of waste materials, said purifying means including filter means of high heat resistant material in said combustion chamber so that deposited particles themselves form a solid filter layer and interposed directly between said combustion chamber and said flue.
Claim 3
Dependent Claim
45 words
An incinerator plant according to claim 1, in which said filter means is arranged directly in the immediate vicinity of said conduit means so that fresh air passed through said conduit means intermixed with flue gases flowing from said combustion chamber to said filter means.
Claim 4
Dependent Claim
37 words
An incinerator plant according to claim 2, in which said filter means comprises filter layer means formed of gas permable fabric forming the filtering surface and also comprises perforated holding means for supporting said filter layer means.
Claim 5
Dependent Claim
38 words
An incinerator plant according to claim 2, in which said filter means comprises filter layer means formed of gas permeable solid bodies forming the filtering surface and also comprises perforated holding means for supporting said filter layer means.
