Abstract (en)
The furnace unit has furnace (1), a heat recovery boiler (2) and a self-locking collar (3). The furnace has an exhaust gas outlet opening (5) with furnace flange (6) circulating over periphery of the exhaust gas opening. The heat recovery boiler has an exhaust gas entrance opening (7) with opening wall (8) circulating above the periphery of the exhaust gas entrance opening. The self-locking collar is movable at the opening wall and can be pressed with a sealing section (10) against the furnace flange such that a gap (4) existing between furnace flange and opening wall is sealed. An inner section (11) of the self-locking collar is closed on the sealing section whereby the inner section extends into the exhaust gas entrance opening. An independent claim is also included for the self-locking collar.
