Method for monitoring inside a chamber of a coke oven, management method for a chamber wall of a coke oven, and monitoring system

Abstract

A coke oven monitoring system capable of quantitatively monitoring changes in the state of the furnace walls in a coke oven with good accuracy has: an oven width measurement device () that measures the oven width; an in-furnace observation device () that photographs the oven walls; and a computer () that analyzes oven width data measured by the oven width measurement device, and oven wall image data captured by the in-furnace observation device. The computer is characterized by including: a oven width/oven wall image data extraction unit () that extracts width data and oven wall image data in different extrusion cycles for the same location of the same kiln; and an oven width/oven wall image data analysis and processing unit () that determines oven wall abnormalities when the oven width data and oven wall image data obtained in the current extrusion cycle have both changed relative to the oven width data and oven wall image data obtained in past extrusion cycles in such a manner as to exceed established values.
