Claim 7

A combustion chamber as defined in claim 4; and further comprising partitions dividing said clearance into a plurality of generally vertical sections; and air supply conduits communicating with the respective sections.

Claim 8

A combustion chamber as defined in claim 5; and further comprising additional partitions dividing said vertical sections horizontally into a plurality of compartments, said conduits each communicating with one of said compartments.

Claim 9

A combustion chamber, particularly incinerators, comprising: first means forming an outer wall bounding a combustion space; second means forming an inner wall bounding said space and comprising a plurality of plates each having an upper and a lower edge region; and cooperating mounting portions on said first means and said upper edge regions of said plates for suspending the plates at least substantially vertically on said first means so as to define a clearance with said outer wall for passing air to the interior of the combustion space; said first means comprising an upright supporting structure and a gas-tight sheet-metal enclosure mounted on said supporting structure; said plates being of ceramic material; said plates being vertically oriented and having a predetermined height in vertical direction; said mounting portions including first mounting portions on said supporting structure which are vertically spaced from one another by a distance smaller than said predetermined height; said plates also having respective upper and lower edges on said edge regions thereof; said mounting portions including second mounting portions on said upper edge regions of said plates, said second mounting portions being substantially hook-shaped and hooked onto a respective one of said first mounting portions so that each plate is suspended from one of said first mounting portions, the lower edge regions of each thus suspended plate being supported against one of said first mounting portions which is adjacent to the first mounting portion from which the respective plate is suspended; said first mounting portions being U-shaped profiles each having a pair of generally horizontal arms including an upper arm against which the lower edge region of a superjacent plate is supported, and a lower arm from which the second mounting portion of a subjacent plate is suspended.
