Abstract

An adjustable chargehole closure for adjusting the closure cover of a charging hole in a coking oven chamber. The adjustable chargehole closure has as an inner frame for a closure cover, and the frame can be rotated both with respect to the closure cover and with respect to an outer frame, designed asymmetrically with respect to a vertical plane, so that the closure cover is displaced along a longitudinal axis when the inner frame is rotated in the horizontal plane. The position of the charging hole opening and the closure cover present therein on the ceiling of a coking oven chamber can thereby be changed without requiring construction measures on the ceiling of a coking oven chamber. The capability is in particular advantageous in order to match the position of the charging hole cover to the precise charging position of the charging machine.
