The invention discloses a one-point three-line
coke cake center temperature measuring method for a large-volume
coke oven, and relates to the technical field of
coke cake center temperature measuring method.The method comprises the following steps that three measuring holes are formed in a grid plate in the middle of a coke guide grid of a coke barrier car in the height direction, and the three measuring holes are measuring points a, b and c in sequence from top to bottom; fixed probes correspondingly matched with the holes of the coke guide grid plate are installed respectively,
temperature measurement is conducted, and the measured value at the measuring point b is the coke cake center temperature, represents the coke maturity condition and is used for guiding increase or decrease of the heating standard temperature of the
coke oven; the difference between the
temperature measurement values at the measurement points a and c represents the heating uniformity of the
carbonization chamber in the height direction and is used for guiding the adjustment of the
combustion state of heating gas of the
coke oven; a measuring hole is formed in the dust hood opposite to a coke guide grid of the coke barrier car, and a fixed probe is installed and matched. The real-time measurement of the center temperature value of the coke cake is realized, and the effects of simple measurement process, accurate data and strong guidance on
coke oven heating are achieved.
