| 摘要 |
The invention relates to a heat exchanger (22) for a mobile solid-fuel firing system (2) comprising a hot gas connection (38) and an inner gas duct (32), a cooling gas connection (58) and an outer gas duct (34) and a wall (30) separating the gas ducts (32, 34) and conducting heat, for producing a heat transfer from the hot gas to the colder gas. Defined gas ducting and a low weight of the heat exchanger can be achieved if the wall (30) comprises a number of interconnected corrugated sheets (74), between which both gas ducts (32, 34) run. |
