Coke oven body inspection/repair management system and method

Abstract

A coke oven body inspection / repair management system is provided with an oven body management server (1) for creating and storing inspection / repair management guideline data relating to a coke oven body, a wall surface management information input means (3) for transmitting, as wall surface management information (4), handwriting-inputted inspection / repair information relating to the wall surface of the coke oven body, which is converted into electronic data, to the oven body management server (1), and an oven body management information input / output means (2) for transmitting, as oven body management information (5), inputted inspection / repair information relating to predetermined portions other than the wall surface of the coke oven body to the oven body management server (1). The oven body management server (1) specifies, from inspection dates and damage levels included in the wall surface management information (4) and the oven body management information (5), the priority of inspection work on a kiln-by-kiln basis and a preferential inspection portion of the kiln, and specifies, from the damage levels included in the wall surface management information (4) and the oven body management information (5), the priority of repair work on a kiln-by-kiln basis and a preferential repair portion of the kiln. Thus, in the determination of the priorities of the inspection work and the repair work, the priorities can be determined with comprehensive consideration given to not only the deterioration of inner wall brick but also the deterioration of other portions (predetermined portions other than the wall surface) of the coke oven body.

Description

technical field [0001] The invention relates to an inspection and repair management system and method for a coking oven body. Background technique [0002] In general, a coke oven is constituted by pairing a carbonization chamber (hereinafter referred to as a kiln) and a combustion chamber. In the coking oven, especially the refractory bricks used for the inner wall of the kiln are exposed to high temperature for a long time and are subjected to side pressure load (coke pressure) from the coke pusher when they are unloaded after carbonization (coke completion). Therefore, with aging of the coke oven, damages due to age-related changes occur in various parts of the kiln, especially the inner bricks of the kiln. Left unattended, these damages are the main cause of various operational failures such as poor carbonization of coal or clogged kilns. In order to reduce the occurrence rate of these operational failures and prolong the life of the coke oven, it is necessary to corre...

AI Technical Summary

Problems solved by technology

[0014] However, in the technology of Patent Document 1, although it is possible to determine the kiln that should be repaired with priority, this priority only uses the inner wall brick damage as an index for kiln deterioration judgment, and there is a problem that the deterioration of other parts of the furnace body is not considered.

Even in the techniques of Patent Documents 2 to 6, there is a problem that the deterioration of inner wall bricks and other parts of the furnace body is not comprehensively considered.
