| 摘要 |
<p>The invention relates to a boiler (1) for burning a fuel, such as wood, and a method for conducting gases in this. The boiler (1) comprises a primary combustion space (4), where fuel is gasified to form primary gases (A), and a secondary combustion space (6), where unburned primary gases (A) are burnt into flue gases (D). In the method, the air (B) required for combustion is taken to the secondary combustion space (6), from where a circulating gas mixture (E) is taken near the area to which the air (B) required for combustion is introduced, and which mixture is subsequently taken to the primary combustion space (4). <IMAGE></p> |
