Abstract (en)
The aim of the present invention is to provide a method and device for partially recycling exhaust fumes (5) from the combustion chamber in a balanced flue boiler. Suitable passages (8.1;8.2) are foreseen to connect the outlet flue (4) of the fumes (5) to the inlet flue (6) of the comburent air (7); said passages (8.1;8.2) being designed to take in part (5.1) of the fumes, that are then mixed with the comburent air (7) thus returning into the combustion chamber. Inside the outlet flue (4) are positioned panels (9) in perforated or streched metal foil, electrostatically charged by well-known means, to filter and retain the suspended particles transported by the fumes (5). <IMAGE>
