| 摘要 |
The invention concerns a device for producing hot water comprising at least one burner (13) arranged to produce rapid combustion inside the combustion chamber. The combustion chamber consists of a sealed container (14) delimiting an internal volume separated from the water so as to allow dry combustion. Said container (14) is immersed in a water section (12) and it is extended by at least one smoke gas diffuser (15) diffusing the smoke gases above the water section within a mass of water showered by spraying means (10). A layer of nodules (11) can be interposed on the path of the smoke gases and the sprayed water so as to increase the thermal exchange generated, by direct contact between the smoke gases and the water spray, and by conduction between container (14) and water section (12). The invention enables to achieve excellent thermal efficiency levels while producing smoke gases with a reduced CO ratio. |
