Abstract

The furnace has a flow monitoring unit in the passage for the fumes to the chimney, and a damper downstream of this unit controlled by a bimetal strip. The damper is so controlled that over the entire temperature range the cross-sectional area left free for the fumes corresponds with the actual flow rate, so that the exhaustion of air from the room is kept small. The damper unit (10) is regulated by the temperature where it is mounted in the gas passage. As the chimney draught increases the damper cross-sectional free area is reduced, and vice versa.
