Abstract (en)
The invention discloses a device for the reduction of the load losses in a fan (2) supplying air to the combustion chamber (10) of a forced-air burner. Said fan (2) comprises an impeller (4) fitted within the body (3) of the fan, wherein a supply spiral-shaped channel (9) and a return channel (21) are obtained, the latter re-conveying the excess air (20) present in the area of the delivery opening (13) to the area (25) of the suction opening (11). Within the return channel (21) is arranged the device according to the invention consisting of at least one baffle plate (1) fit to guide the re-conveyed air (20) to the area (25) where it converges with the sucked-in flow (26), the ensuing motion being essentially non-turbulent. <IMAGE>
