Abstract
A flue tuning and emissions saving system is disclosed. The device or system includes an inlet duct (20) having an inlet cross-sectional area and an outlet duct (18) having an outlet cross-sectional area that is the same as the inlet cross-sectional area. An outer duct (16) that is of an outer duct cross-sectional area is sealingly connected to the inlet duct (20) and the outlet duct (18), while separating the inlet duct (20) and the outlet duct (18). At least one disc (12) that is positioned at a specified distance S between the inlet duct (20) and at the same S to the outlet duct (18) and centered in the outer duct, the disk (12) includes a specified disc area so that flow of an exhaust gas entering the system through the inlet duct (20) will be diverted by the disc (12) into the outer duct (16) before the flow continues to the outlet duct (18) without encountering a restriction in flow cross-sectional area. When two or more discs are used, an annular fin (22) that extends from the outer duct to create a passage of the inlet duct (20) diameter that separates the discs.
