| 摘要 |
The invention relates to a boiler which operates on the principle of wood gasification, meant to be used in heating dwellings and preparing hot domestic water at high efficiency as a consequence of heating the combustion air, by using the energy of exhaust gases, and of increasing the surface of heat exchange between the burnt gas chamber and the water chamber, by adding some cells. According to the invention, the boiler comprises a heating chamber (i) wherein combustion air enters through a draft door (3) opened by the draft regulator and having a profiled partition wall (5) which forces the combustion air through a sinusoidal path passing through some zones (b, c and d) in contact with a wall (e) of the burnt gas discharge chamber, after which it branches into two components, the primary combustion air and the secondary combustion air, the flow rates of which are controlled by two valves (9 and 10), the burnt gas chamber (e) transferring the heat to the water chamber (f) through a partition wall (7) and some metallic cells (6). |
