Abstract

The construction of the sealing strip of the coking chamber furnace door, which ensures the hermetic separation of the furnace space from the outside atmosphere. The sealing strip of the coking chamber door is designed as a divided rectangular frame and is characterized by the fact that rectangular support supports (3, 4) are welded to the ends of the vertical longitudinal members (1, 2) of the sealing strip frame, to which the horizontal cross member (5) of the sealing strip is loosely attached from the inside.

Description

The invention solves the construction of the coke chamber sealing strip of the coke oven chamber, which ensures a hermetic separation of the furnace space from the outside atmosphere.

Coke ovens of modern design are equipped with self-sealing doors on the machine and coke side of the coke oven battery, which achieve the required tightness by metal-to-metal contact so that the edge of the furnace door formed by the steel angle edge abuts the machined surface of the furnace frame. The joint of the cutting edge and the furnace frame is self-sealing during the coking with tar condensed from the carbonizing gases, which jumps under high temperature. To increase the sealing effect, the bevel surface of the lip of the sealing strip is oriented to the side of the furnace door lining holder and is therefore oriented to the furnace space where it creates a wedge space in which tar condensate collects and pressurized the furnace atmosphere into the gap between the blade and the furnace door frame . However, modern large-capacity coke oven batteries with a chamber height of about seven meters pose a problem with the thermal deformation of the furnace frames. The noticeable thermal difference between the threshold with the ceiling of the coking chamber makes the furnace door tend to bend. Even a plurality of thrust brackets cannot ensure that the sealing strip formed as a rigid rectangular frame is pressed over the entire circumference to the furnace frame, which is wavy deformed.

and four of the coke features of the invention of the sealing strip are from the inside

The aforementioned drawbacks are eliminated by the sealing strips of the sealing chambers formed as a rectangular frame, and that the rectangular bearing supports are welded to the ends of the vertical longitudinal members, to which the horizontal cross-member of the sealing stripe is loosely applied.

The subdivision of the gasket frame into loose elements eliminates the spatial deformation common to welded, rigid frames and allows easy alignment of unbound longitudinal members and crossbeams by the pressure of the bearing bracket adjusting screws, since the compensation of the deformations formed is limited to curve correction.

In an exemplary embodiment, the invention is illustrated schematically in the accompanying drawing, which is a view of a portion of a seal rail frame assembly.

The podélníkům 1, 2 are welded to a bearing support 4 which is inserted from the inside of the crosspiece free longitudinal members 1,2, the upper crossmember £ i's bottom, not shown in the drawing _transoms are then conventionally using brackets -řítlačných pecnímu pressed against the frame.
