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.

Abstract: A coking oven has a battery of longitudinally extending and transversely spaced coking chambers each provided with a plurality of downwardly open and longitudinally spaced filling holes. Coal is charged into the chambers through the respective filling holes. A respective longitudinally movable leveling rod in each of the chambers can level coal charged by the filling equipment into the chambers. Sensors provided on the leveling rods scan from above transversely and longitudinally spaced points on a surface of the coal charged through the holes into the respective chambers. A controller connected to the sensors records a respective measurement corresponding to a vertical position of the surface at each the points and determines from the measurements thereof a three-dimensional filling-level profile of the surface of the charged coal for controlling operation of the filling equipment and filling of the chambers with the coal.

Abstract: A method for producing non-recovery/heat recovery coke may include the steps of providing a container, disposing a volume of loose coal into the container such that a vertical dimension of the volume of loose coal in the container is smaller than a horizontal dimension of the volume of loose coal, applying a force to the coal in the container to produce a volume of compacted coal having a substantially uniform density which is larger than that of the loose coal, disposing the compacted coal into a non-recovery/heat recovery type oven, and heating the compacted coal to produce coke. The method may also include the steps of providing a container, and moving the non-recovery/heat recovery coke mass from the oven at a substantially constant elevation to the container, quenching the coke mass in the container to produce a quenched coke mass, and removing the quenched coke mass from the container.

Abstract: The invention concerns an evaporator, especially for the sugar industry, with at least two heat exchangers, into the top of which the medium to be concentrated is loaded and which are heated with steam with different compositions and/or different pressures in a cross stream, wherein the concentrated medium and the exhaust steam generated, after they come out of the heat exchanger, are carried off separately. To produce an evaporator that is simple and inexpensive in design, the invention proposes that the medium to be concentrated be loaded by a medium distribution common to all heat exchangers and the medium leaving the first heat exchanger go directly into the next heat exchanger. Only after the medium comes out of the second heat exchanger are the exhaust steam and the medium separated. The steam spaces in the heat exchanger separated from the exhaust steam space are separated from one another by a common dividing wall.
