Abstract
Abstract Incinerator for incinerating houshold refuse or industrial waste wherein the combustion air is blown obliquely into the incinerator through a grate at such a pressure that the refuse mass is not only fluidised by said air flow but is also transported through the incinerator. The incinerator is particularly suitable to be mounted in a refuse-collecting van so that the collected waste can be immediately incinerated and the number of return trips to a dump can be reduced to a minimum.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
98 words
An incinerator for household refuse, industrial waste, and like material, comprising a combustion chamber having a stationary grate means, means for supplying combuStion air through said grate means, and filling and discharge means, characterized in that said grate means includes deflecting members for directing said combustion air in a manner to lift said material being treated in the incinerator whereby said material is torn apart and brought into a fluidized state, and whereby owing to a pre-determined orientation of the air effected by said grate means, the combustion air also serves to transport said material through said incinerator.
Claim 2
Dependent Claim
98 words
An incinerator for household refuse, industrial waste, and like material, comprising a combustion chamber having a stationary grate means, means for supplying combuStion air through said grate means, and filling and discharge means, characterized in that said grate means includes deflecting members for directing said combustion air in a manner to lift said material being treated in the incinerator whereby said material is torn apart and brought into a fluidized state, and whereby owing to a pre-determined orientation of the air effected by said grate means, the combustion air also serves to transport said material through said incinerator.
Claim 3
Dependent Claim
47 words
Apparatus according to claim 1, wherein the furnace is divided into a plurality of combustion zones, each zone having a supply of air of different rate of flow, pressure and temperature, and each zone having grate openings and deflecting means adapted to the function of such zone.
Claim 4
Dependent Claim
59 words
Apparatus according to claim 1 wherein the furnace and at least part of said means for supplying combustion air is surrounded by secondary combustion chambers for the secondary combustion of a combustion gas withdrawn from said furnace so that said combustion air is pre-heated through heat exchange between said secondary combustion chambers and said means for supplying combustion air.
Claim 5
Dependent Claim
17 words
Apparatus according to claim 3, wherein the gas circulation in said secondary-combustion chambers is controlled by valves.
Claim 6
Dependent Claim
20 words
Apparatus according to claim 2 wherein said combustion zones are located one behind the other, and said furnace is tunnel-shaped.
Claim 7
Dependent Claim
15 words
Apparatus according to claim 2 wherein the combustion zones are located one above the other.
Claim 8
Dependent Claim
16 words
Apparatus according to claim 1 characterized by means in said filling means for comminuting the refuse.
Claim 9
Dependent Claim
12 words
A refuse-collecting van provided with an incinerator as claimed in claim 1.
