Coke oven door seal

Patent ·
OSTI ID:5001680
A coke oven door seal in which a leaf spring is fixed to the inner end of a continuous concave seating structure which is peripherally mounted on the door frame. A terminally convex ridge structure extends endwise from the door jamb to flex the leaf spring sufficiently so as to form a continuous gas tight seal around the door. The leaf spring is flexed by the ridge by an amount that is greater than the deflection which would result only from the application of pressure on the leaf spring by coke oven gases. The leaf spring is also flexed by an amount that is less than the amount which would surpass its elastic limit. In an alternate embodiment, the leaf spring and seat structure are mounted on the door jamb while the ridge is mounted on the door frame.
