Abstract
Abstract A regenerator lining for regenerator chamber cells in coke ovens, comprises a stone or brickwork having either a honeycomb or lamellar structure, with a plurality of gas passages extending therethrough and terminating in openings on the top and bottom sides of the structure. The transverse portions or sides are made of frame portions having a material thickness of up to 20mm. The webs or spacing between the openings is up to 10mm in thickness. In the case of circular, hexagonal, or similar shape passages, the openings have diameters of up to 16mm and in a construction which includes a slot formation, the slots are made up to 16mm wide.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
123 words
A regenerator lining for regenerator chamber cells in coke ovens, comprising a stone having a plurality of internal gas passages extending therethrough and side frame portions and top and bottom surfaces with openings for the gas passages and including wall formations between the openings, said frame portions having a material thickness of up to 20 mm, said wall formations between openings being up to 10 mm in thickness and said passages and openings being up to 16 mm wide and no less than a size to permit flow the gases therethrough, the specific ratio of the stone surface participating in the heat exchange to the stone mass total is from 0.08 to 0.12 m 2 of stone surface per kilogram of stone mass.
Claim 2
Dependent Claim
