Leveller bar for coking ovens

Abstract

The invention relates to a levelling bar for coking ovens, for levelling the cones of discharged coal which form under the filling holes of the oven chamber during the filling process. The levelling bar consists of two cheeks, such as plates ( 1 ), which extend essentially over the entire length of the ranged at a distance from each other depending on the width of the oven chamber, and parallel to each other. They are also interconnected and are essentially vertical. The levelling bar also has transversal coal carriers ( 2 ) which are arranged in the intermediate space delimited by the cheeks ( 1 ) at a mutual distance, one behind the other and which only extend over part of the cross-sectional surface of the levelling bar formed between he cheeks ( 1 ). The height ( 3 ) of the coal carriers ( 2 ), which take up the entire interval between the cheeks, is less than the height (H) of the cheeks ( 1 ) and the cheek form a gas channel ( 6 ) above the coal carriers ( 2 ) which is essentially free of built-in components.

Description

technical field [0001] The invention relates to a flat coal rod for a coke oven. Background technique [0002] From the European patent EP 0 483 497 B1 a flat coal rod is known which consists of vertical jaws made of steel plates arranged parallel to one another in the longitudinal direction of the furnace, wherein in the middle area delimited by the jaws according to Horizontal and upright coal scrapers in the form of steel plate walls of the same height as the jaw plates are arranged equidistantly. Before the loose coal cone formed during the coal charging process under the coal charging hole of the coking chamber reaches the reserved air collection chamber, the flat coal rod is introduced into the coking chamber through the small flat coal furnace door and moves back and forth, thereby leveling the loose coal Coal cone. In order not to block most of the air collection chamber above the coal during the coal charging process after the flat coal rod is inserted into the fu...

AI Technical Summary

Problems solved by technology

[0003] This kind of flat coal rod has been proved to have such a problem: in the process of leveling coal, although the alternate middle area of ​​the flat coal rod between the jaw plate and the free end of the coal scraper can pass through the leveled coal to make the alternate middle The area is closed, but it is no longer possible for the charging gas to be pumped unhindered to the receiver, resulting in more or less uncontrolled emissions, since it is no longer possible for the charging gas to be pumped through the standpipe
