Wall protector for a heating wall head between two oven chamber openings of a coke oven battery
A coke-oven battery has at least two chambers separated by a heating wall head and having openings provided with vertical jambs juxtaposed with the head. An upright anchor post is spaced horizontally forward from the head, and a plurality of U-shaped yokes are provided between the post and the head. Biasers bear on the anchor post and press the yokes against the jambs and thereby press the jambs against the head. A thin-walled sheet-metal head cover having upright edges is clamped between the jambs and the head and extends horizontally as a single piece between the jambs.
1. In combination with a coke-oven battery having at least two chambers separated by a heating wall head and having openings provided with vertical jambs juxtaposed with the head,
an upright anchor post spaced horizontally forward from the head;
a plurality of U-shaped yokes between the post and the head;
biasing means bearing on the anchor post and pressing the yokes against the jambs and thereby pressing the jambs against the head; and
a thin-walled sheet-metal head cover having upright edges clamped between the jambs and the head and extending horizontally as a single piece between the jambs.
2. The combination defined in claim 1 , further comprising
sealing material between the edges of the sheet-metal head cover and the jambs or head.
3. The combination defined in claim 2 wherein the sealing material is between the edges and the head.
4. The combination defined in claim 1 wherein the head has an outer face that is generally flat and the head cover is nonplanar and forms with the head outer face a cavity.
5. The combination defined in claim 4 wherein the edges of the head cover lie in a common plane flatly against the head outer face and the head cover has a planar central part spaced outward from the plane and connected to the edges by unitary webs generally perpendicular to the plane.
6. The combination defined in claim 4 , further comprising
a mass of thermal insulation generally filling the cavity.
7. The combination defined in claim 6 wherein the mass is comprised of mats of aluminum silicate.
