Abstract
Vorrichtung zur Vermeidung einer Abgasrückströmung bei einem Heizkessel im Überdruckbetrieb, wobei mehrere Heizkessel eine gemeinsame Abgasleitung aufweisen, und eine Zuluft-Leitung jedes Heizkessels ein ihren Querschnitt verschließendes Sperrorgan aufweist. Das Sperrorgan ist als Rückschlagklappe (1) ausgebildet. Die Rückschlagklappe weist mindestens ein Klappenteil (4) auf, welches an einer rahmenartigen Haltung (3) schwenkbeweglich angelenkt ist, wobei die Halterung als in die Zuluft-Leitung einbaubarer Einsatz ausgebildet ist. An dem Klappenteil sind Schließgewichte (14) angeordnet, und das Klappenteil und die dem Klappenteil zugeordnete Halterung weisen miteinander in Anlage bringbare Dichtflächen (6,7) aus weichelastischem Werkstoff auf. Device for preventing an exhaust gas recirculation in a boiler in the overpressure operation, wherein a plurality of boilers have a common exhaust pipe, and a supply air line of each boiler has a cross-section closing obturator. The blocking member is designed as a non-return valve (1). The non-return valve has at least one flap part (4), which is pivotably articulated to a frame-like posture (3), wherein the holder is designed as an insert which can be installed in the supply air line. Closing weights (14) are arranged on the flap part, and the flap part and the holder assigned to the flap part have sealing surfaces (6, 7) made of soft elastic material which can be brought into abutment with each other.
