Combustion chamber-carbonization chamber wall structure of coke oven

Abstract

The invention relates to a combustion chamber-carbonization chamber wall structure of a coke oven. A combustion chamber-carbonization chamber is formed by arranging combustion chambers and carbonization chambers alternately, wherein each combustion chamber consists of multiple parallel vertical flame channels; flame channel partitions are arranged among the vertical flame channels, carbonization chamber walls are arranged between the carbonization chambers and the vertical flame channels, and concave-convex meshing structures are arranged in positions where the vertical flame channel partitions in the combustion chambers and the carbonization chamber walls are connected; the inner surface of one side, facing the corresponding vertical flame channel, of each carbonization chamber wall adopts a concave structure, and the thickness of the concave inner surface is 10-15 mm smaller than that of each carbonization chamber wall. The heat transfer efficiency of the combustion chamber-carbonization chamber can be significantly improved while the structural strength of a coke oven body and the air tightness of the combustion chamber-carbonization chamber are guaranteed, the coking time can be shortened, the coke yield can be increased, the production efficiency of the coke oven can be improved, and large-scale development of the coke oven is better facilitated.

Description

technical field [0001] The invention relates to the technical field of coking, in particular to a coke oven combustion chamber-carbonization chamber wall structure. Background technique [0002] Such as figure 1 As shown, the uppermost part of the modern coke oven body 1 is the furnace roof, and below the furnace roof are the combustion chamber 3 and the carbonization chamber 2 arranged alternately. The lower part of the coke oven body 1 has a regenerator 6 connected to the regenerator 6 and the combustion The chute area 5 of the chamber 3, the small flue 7 at the bottom of each regenerator 6 is connected with the flue through an exchange switch, and the end of the flue leads to the chimney. The combustion chamber 3 is on both sides of the carbonization chamber 2, and is composed of many vertical fire channels 8. The gas burns in the vertical fire channels 8, and the heat is transferred to the carbonization chamber through the carbonization chamber wall 4 between the vertic...

AI Technical Summary

Problems solved by technology

Since the heat transfer surface of the conventional carbonization chamber wall 10 is an equal-thickness surface, if the heat transfer efficiency between the combustion chamber and the carbonization chamber is to be improved, the overall thickness of the carbonization chamber wall 10 can only be reduced, but this reduces the thickness of the coke oven body. 1 Structural strength and airtightness of combustion chamber-coking chamber
