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

摘要

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 (6) that measures the oven width; an in-furnace observation device (7) that photographs the oven walls; and a computer (10) 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 (10a) 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 (10b) 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.;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 (6) that measures the oven width; an in-furnace observation device (7) that photographs the oven walls; and a computer (10) that analyzes oven width data measured by the oven width measurement device, and oven wall image data captured by the in-furnace observation device.

1. A method for monitoring inside a chamber of a coke oven comprising:
obtaining pieces of chamber width data and pieces of chamber wall image data in different extrusion cycles at a same location in a same carbonization chamber in a coke oven; calculating and numerically processing a finite difference between the piece of chamber width data in a current extrusion cycle and the piece of chamber width data in a past extrusion cycle and a finite difference between an area of a chamber wall damaged portion in the current extrusion cycle and an area of a chamber wall damaged portion in the past extrusion cycle using the pieces of chamber wall image data; obtaining a conical volume of a changed portion of the chamber wall from a distance XL along an X axis obtained from the calculated and numerically processed finite difference from the pieces of chamber width data and an area S of a peeled off portion obtained from the calculated and numerically processed finite difference from the pieces of chamber wall image data; and determining a chamber wall abnormality in accordance with a change in the volume.
