Problems solved by technology

[0004] The purpose of the present invention is to provide a heat recovery coke oven main wall flue structure, which overcomes the deficiencies of the prior art, improves the heat capacity of the heat storage bricks, reduces the temperature when exposed to cold air, and solves the problem of heat recovery coke ovens in coke pushing and coal charging. When the furnace wall cools down too fast, the furnace temperature is too low, so that the time to return to the normal furnace temperature can be shortened after coal charging and coke discharge, thereby shortening the coking time and increasing the coke production capacity

Embodiment Construction

[0017] Below in conjunction with embodiment technical scheme of the present invention will be further described:

[0018] In the description of the present invention, it should be noted that unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection. Connected, or integrally connected; either directly or indirectly through an intermediary. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention in specific situations.

[0019] See Figure 1-Figure 3 , is a structural schematic diagram of a heat recovery coke oven main wall flue structure embodiment of the present invention, a castable center column 10 is arranged at the coke oven center line of the main furnace wall 1, and any carbonization chamber includes two main furnace walls 1. There is a group of main wall flues in th...

Abstract

The invention relates to the technical field of heat recovery coke ovens in the metallurgical industry, in particular to a main wall flame path structure of a heat recovery coke oven. The main wall flame path structure is characterized in that any one carbonization chamber comprises two main oven walls, any one main oven wall is internally provided with a main wall flame path consisting of two ascending flame paths and three descending flame paths of the carbonization chamber and another main wall flame path consisting of two ascending flame paths and three descending flame paths of an adjacent carbonization chamber, the two main wall flame paths are symmetrically arranged on the two sides of a central column, the distance h between a machine-side or coke-side front face line and the nearest side flame path is 2720 + / - 100 mm, and a ratio of the thickness m of the main furnace wall to the width k of the carbonization chamber is 0.2-0.3. The main wall flame path structure of the invention has the advantages that the defect that the furnace wall is thoroughly cold during coke pushing and coal charging of the heat recovery coke oven is effectively overcome, and the purposes of shortening the time for recovering a normal furnace temperature after coal charging and coke discharging, shortening coking time and increasing coke productivity are effectively achieved.

Description

technical field [0001] The invention relates to the technical field of heat recovery coke ovens in the metallurgical industry, in particular to a heat recovery coke oven main wall flue channel structure. Background technique [0002] Heat recovery coke oven in the metallurgical industry refers to a coke production device that uses micro-negative pressure operation in the coke oven carbonization chamber, mechanized tamping, coal charging, coke discharge, and recovery and utilization of waste heat from coking combustion exhaust gas. The main wall flue structure of heat recovery coke oven in the prior art is generally composed of 14 descending flues and 8 ascending flues, a total of 32 flues, and the thickness of the furnace wall is 696mm. The large quantity and the narrowing of the furnace wall thickness will easily lead to the extremely unfavorable working conditions of pushing coke in the heat recovery coke oven, and the furnace wall is "cool through the heart" when charging...
