Problems solved by technology

It should close the oven cavity hermetically so that no fine particles can seep out of the oven cavity, which would make the operation of the coke oven cavity difficult and be dangerous for the environment and problematic for the operation of the coke oven

Embodiment Construction

[0056] figure 1 : The coke oven chamber (1) is loaded with coal and closed with a door (2) made of refractory material. Preferably, materials containing silica or containing silica and alumina are suitable as the refractory material. The horizontally oriented wall ( 3 ) surrounding the furnace door is likewise made of this material, so that the door cannot be distorted due to the same coefficient of thermal expansion. The door is suspended from a support frame (4) on which a coupling (4a) to the drive mechanism is fixed for pulling out the door. On this support frame there is likewise a connecting piece ( 4 b ) for the lift gate. Access to the coke oven (1) can thus be obtained. In the coke oven there are coke cakes ( 5 ), which are not filled all the way to the top of the coke oven, but only up to a defined filling level. Above the coke cake there is a gas collection chamber (5a). Ventilation openings (6) are located on the coke oven roof (7), through which the primary a...

Abstract

The invention relates to a heat-resistant door device for closing a horizontal coke chamber oven, said device being made of fire-proof material, wherein particularly a silica-containing material or a silica and aluminum oxide-containing material is used. The material has a low temperature expansion coefficient and has good heat insulating properties such that the door does not warp and does not become deformed during the coking process. The door device is configured by a door-surrounding coke oven wall located substantially above the door and a moveable door located beneath. Thus less cold ambient air enters the coke oven chamber during the coke discharge and the radiation loss is minimized. The door may comprise an ellipsoid convexity, with which the coal can be discharged more easily into the coking chamber. The oven wall surrounding the oven chamber may also be made of a fire-proof silica-containing or a fire-proof silica and aluminum oxide-containing material.

Description

technical field [0001] The present invention relates to a closure device for a coke oven, as is usually the case in so-called "heat-recovery" or "non-recovery" coke oven systems. The invention also relates to a method for operating a coke oven with the closure device according to the invention. The closing device closes the horizontally oriented openings of the coke oven battery as gas-tight as possible. Such openings on the furnace walls on the front and rear sides are used for horizontal cavity coke ovens. Charge, which is cyclical and pushed out and recharged after the coking process. Background technique [0002] Some types of coke ovens are also charged through orifices provided in the roof region. The openings provided in the side walls of the oven are then smoothed with a leveling device, for example a leveling bar. As a result, the conical piles that often occur during charging, which are unfavorable for the coking process, are smoothed and the pile density of t...
