Claim 9

The incinerator of claim 1 wherein the combustion chamber further comprises: another substantially straight wall portion extending between said long leg of the J-shaped wall portion and said other end wall of the preheater, said other substantially straight wall portion and said long leg of the J-shaped wall defining mutually substantially perpendicular inner wall surfaces of the combustion chamber that are remote from said rounded wall portion and cooperate with one another to produce turbulence in gas flowing along them towards the tubes, one of said inner wall surfaces being oriented substantially horizontally so that particulate matter carried by the gas can settle onto it for collection.

Claim 10

the rounded portion of said J-shaped wall being inwardly concave, curved on a substantially uniform radius through about 180*, and joined to an edge of the burner zone that is remote from said straight long leg so that a substantial part of said rounded wall portion is in opposing, spaced relation to the burner zone to compel gas flowing out of the burner zone to undergo a reversal of direction in flowing through the combustion chamber and to reflect heat from the burner zone into substantial portions of the interior of the combustion chamber, thus subjecting substantially all portions of gas flowing through said chamber to reflected heat.

Claim 11

the rounded portion of said J-shaped wall being inwardly concave, curved on a substantially uniform radius through about 180*, and joined to an edge of the burner zone that is remote from said straight long leg so that a substantial part of said rounded wall portion is in opposing, spaced relation to the burner zone to compel gas flowing out of the burner zone to undergo a reversal of direction in flowing through the combustion chamber and to reflect heat from the burner zone into substantial portions of the interior of the combustion chamber, thus subjecting substantially all portions of gas flowing through said chamber to reflected heat.

Claim 12

THE ROUNDED PORTION OF SAID J-SHAPED WALL BEING INWARDLY CONCAVE, CURVED ON A SUBSTANTIALLY UNIFORM RADIUS THROUGH ABOUT 180*, AND JOINED TO AN EDGE OF THE BURNER ZONE THAT IS REMOTE FROM SAID STRAIGHT LONG LEG SO THAT A SUBSTANTIAL PART OF SAID ROUNDED WALL PORTION IS IN OPPOSING, SPACED RELATION TO THE BURNER ZONE TO COMPEL GAS FLOWING OUT OF THE BURNER ZONE TO UNDERGO A REVERSAL OF DIRECTION IN FLOWING THROUGH THE COMBUSTION CHAMBER AND TO REFLECT HEAT FROM THE BURNER ZONE INTO SUBSTANTIAL PORTIONS OF THE INTERIOR OF THE COMBUSTION CHAMBER, THUS SUBJECTING SUBSTANTIALLY ALL PORTIONS OF GAS FLOWING THROUGH SAID CHAMBER TO REFLECTED HEAT.
