We, in an off-line distribution testing equipment, have developed a device capable of measuring the stack profile with high accuracy through an ultrasonic sensor. We have further devised a method which derives distribution of inclination angle, angle of repose and terrace length quantitatively and automatically by making use of the measurement data acquired from the device. We have also invented a method estimating theoretically the stack profile at peripheral and confirmed that it accords well with the measurement results obtained from the experiment or at an actual furnace.
