Abstract
Abstract Apparatus for burning waste matter in a combustion chamber comprising a feed bed with a plurality of stepped sections. Combustion air is introduced in the region of the transition from one stepped section to the next. The upper sides of the stepped sections are closed and the sections lie on an inclined frame which is connected to a vibrator.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
191 words
Apparatus for burning waste matter comprising; a longitudinally inclined feed bed carrier provided with means for vibrating said carrier; a plurality of hollow step-forming sections mounted in fixed positions transversely on said carrier so as to present a support surface for said waste matter that is substantially continuous except for openings in the risers of said stepped surface; said step-forming sections being shaped so that, as disposed on said carrier, their forward edges are lower than their junctions with the bottom of the riser of the next higher stepforming section and shaped so tHat openings are formed in the risers communicating with the interior of said sections and so that the floor of said openings rises rearwardly so as to oppose flow of waste matter from the stepped surface rearwardly into the openings; means for introducing combustion air into the space between said carrier and said stepped sections for supplying said air through said riser openings to the combustion of said waste matter, and retaining side walls mounted in fixed positions on said carrier and extending above said stepped surface on either side to prevent sideways escape of said waste matter.

Dependent Claim

Apparatus for burning waste matter comprising; a longitudinally inclined feed bed carrier provided with means for vibrating said carrier; a plurality of hollow step-forming sections mounted in fixed positions transversely on said carrier so as to present a support surface for said waste matter that is substantially continuous except for openings in the risers of said stepped surface; said step-forming sections being shaped so that, as disposed on said carrier, their forward edges are lower than their junctions with the bottom of the riser of the next higher stepforming section and shaped so tHat openings are formed in the risers communicating with the interior of said sections and so that the floor of said openings rises rearwardly so as to oppose flow of waste matter from the stepped surface rearwardly into the openings; means for introducing combustion air into the space between said carrier and said stepped sections for supplying said air through said riser openings to the combustion of said waste matter, and retaining side walls mounted in fixed positions on said carrier and extending above said stepped surface on either side to prevent sideways escape of said waste matter.
Claim 3
Dependent Claim
36 words
Apparatus according to claim 1, in which the width of the feed bed decreases in the direction of movement of the burning material, converging longitudinal ribs being provided on the upper side of the feed bed.
Claim 4
Dependent Claim
46 words
Apparatus according to claim 1, in which the cross-sectional shape of the feed bed varies in the direction of movement of the burning material, the support surface of the feed bed being transversely flat at the top and merging at the bottom into a concave shape.
Claim 5
Dependent Claim
22 words
Apparatus according to claim 1, in which the stepped sections are made at least partly of a compacted refractory mineral ceramic material.
Claim 6
Dependent Claim
42 words
Apparatus for burning waste matter as defined in claim 1, in which said step-forming sections have an interior shape such that said combustion air streams out of said openings in a direction substantially parallel to the top surface of the adjacent step.
Claim 7
Dependent Claim
77 words
Apparatus for burning waste matter as defined in claim 1, in which said step-forming sections have a lower portion shaped so as to meet tightly and to extend the surface of the next lower section and thereby to provide the rearwardly rising floor for said riser openings and further shaped so as to provide a deflector for causing the combustion air supplied to said openings to stream substantially parallel to the surface of said next lower step.
Claim 8
Dependent Claim
59 words
Apparatus for burning waste matter as defined in claim 1, in which said step-forming sections overlap, so that the overlapped portion of a lower section provides the rearwardly rising floor for said riser openings and also a deflector for causing the combustion air supplied to said openings to stream substantially parallel to the top surface of said lower section.
Claim 9
Dependent Claim
48 words
Apparatus for burning waste matter as defined in claim 1, in which at least one of said side walls is of stepped form providing shallow downstream-facing risers having additional combustion air orfices, and in which means are provided for supplying a flow of air through said additional orfices.
