Reactor chamber door for large-scale coking reactors

Heating system for regenerative coke ovens

Coking system, wherein the coking blends particularly based on hard coal, are fed batchwise to a reactor (1), which is heated indirectly by heat recovery in regenerators (I, II) or recuperators, whereby the reactor is built as a high-capacity coking reactor (100), several high-capacity coking reactors are combined to form a reactor block and the high-capacity coking reactors are built as mutually independent modules, whereby each module can be operated or optionally replaced independently of the neighboring modules, with little or no impairment of the operation of the neighboring modules. The individual reactors are independently operatable in terms of statics and heat supply. The regenerators, or recuperators (I, II, R, R') can be arranged laterally or underneath the reactor chamber. Neighboring reactors can have a common intermediate wall (2). The reactor chambers have a width of at least 0.7 m, a height of at least 8.5 m and a length of at least 18 m.

The amount of flexure of a heating wall of a coke oven is determined during operation of the coke oven by providing an observation hole through the oven roof into a heating flue, the observation hole having an axis. On at least one of the binder walls defining the heating flue is formed a vertical measuring strip extending throughout substantially the entire height of the binder wall at a position to be visible through the observation hole. The measuring strip defines, prior to heating during operation of the coke oven, a rectilinear reference line extending parallel to and spaced from the axis of the observation hole. Upon operation of the coke oven, during which time the heating wall is heated and flexes, the degree of such flexure is determined by measuring through the observation hole the extent of deviation of the measuring strip from the reference line.

An apparatus for transferring between chambers of a coke oven charging gases which develop during the charging of the chambers, while preventing the escape of the gases to the surrounding environment, includes first and second covers mounted for movement between first positions closing charging openings through an oven roof and second positions uncovering such openings. Ducts surround the peripheries of the first and second openings, such ducts being filled with a displaceable sealing medium. First and second housings form respective first and second compartments enclosing the first and second covers, respectively, at all positions thereof. The first and second covers have apron members extending into the displaceable sealing medium in the respective ducts when the covers are in the first positions thereof. The housings have at lower portions thereof seals for sealing the compartments from the exterior. First and second lifting devices are associated with the respective housing to move the first and second covers, respectively, within the respective compartments between the first and second positions of the covers. A transfer duct extends between the first and second compartments for, upon the covers being moved from the first positions thereof, transferring charging gases between the chamber openings via the compartments.

A method and apparatus for the wet quenching of coke is disclosed wherein hot coke is sprayed from above with quenching water, the steam generated by the heat of the coke is condensed by a spray of condensation water from the top of the quenching tower, and the hot condensate-water mixture is collected at the bottom of the quenching tower and recirculating to the top of the tower where it is sprayed between quenching operations to be cooled by a counterflowing stream of air. The cooled condensate-water mixture is suitable for reuse as the condensation spray water.

A coke oven door, which is positioned within a door frame in a closed position, has inner and outer sealing strips which contact the door frame. The two sealing strips jointly form a gas guide duct with the door frame. The inner sealing strip forms an elastic and flexible seal which prevents solids from passing into the guide duct but which allows gas to pass thereto. The outer sealing strip forms a gas-tight nonflexible seal.

A coke oven hopper truck is movable along a coke oven cover which has therein filling holes closed by removable filling covers. The hopper truck has supported thereon a lifting device including an electromagnet which lifts and lowers the filling covers from and into the filling holes so that the filling covers may be removed from the filling holes, whereby coal may be charged through the filling holes into the coke oven chamber. The movable hopper truck has supported thereon repositories for supporting the filling covers after they have been removed from the filling holes by the lifting device. The repositories are movable with the hopper truck along the coke oven cover. The repositories have therein recesses dimensioned to receive therein the filling covers. Cleaning tools such as scrapers or brushes are provided along the edges of the recesses, and the lifting device rotates the filling covers against the cleaning tools to thereby clean the filling covers.

A track rail support includes ties positioned at spaced intervals along a base and supporting track rails. An elongated intermediate carrier is positioned between the ties and each track rail. Secondary track rail supports in the form of block-shaped elements are positioned in contact with the intermediate carrier. Each block-shaped element is positioned above a position midway between two adjacent ties.

A valve chamber which communicates through flue openings with bottom flues has therein a pair of dosing frames, each mounted on a pivot and movable thereby between a closed position against the openings and an open position withdrawn from the openings. Each pivot is attached to one end of an elongated eccentric member to the other end of which is attached a spring which urges the respective dosing frame to the closed or open position thereof. One or two pull rods are attached to the eccentrics to sequentially move the closed dosing frame away from the openings to the open position thereof, and to then move the open dosing frame to the openings to the closed position thereof.

Changeover device for controlling the movement of dosing frames

A gas pipe has positioned in the interior thereof, and along the entire length thereof, a loose gas displacement body formed of an incombustible material, such as mineral wool or glass wool. The body may be a hollow cylinder divided longitudinally, and further divided into partial bodies placed within the pipe in serial succession.

An inclined chamber has vertical heating flues on each side thereof. The floors of the heating flues are vertically staggered in an inclined manner. Pairs of heating flues are joined at the tops thereof by guide openings which are vertically staggered in an inclined manner. Central and upper air inlet openings extend into the heating flues and are vertically staggered in an inclined manner.
