A method of judging the state of carbonization by the temperature distribution formula of the gas generated during the carbonization of coal

摘要

The present invention relates to a method of determining a combustion management state of a coke oven. The method includes collecting temperature data of a raw gas (RAW gas) generated during coal combustion and calculating a quadratic equation Y = aX²+ bX + C (a, b, c are coefficients, Y is the temperature of the roug gas, . . (1), and finds ovens that are abnormal in the combustion state by comparing and analyzing the slope using equation (1) for each oven, and the formula Y '= 2aX + b . . . (When Y '= 0) from the maximum temperature reaching time (2) and comparing the time of each oven to the kiln, it is possible to quickly detect the inferior heat temperature and the defective hot temperature oven, In addition, the number of times of measurement under high temperature and high dust working conditions can be greatly reduced by measuring the number of times of operation such as temperature measurement and 9 times of hot temperature measurement within 5 days of daily use only in defective oven determination. This is a method for judging the state of the carbon monoxide by the temperature distribution formula of the generated gas.
