Hot gases from e.g. a burner (7) are passed through openings (8, 9) in a series of flanges (2) which are connected together by a number of rings (3) that form one or more exhaust gas channels (10). The flanges are in direct contact with the rings, exhaust gases and surrounding air. A flow of air can be passed over the flanges using e.g. a fan. |
