First Claim
Patent Images
1. A method for assisting an operator in cutting coke in a coke drum comprising:
- measuring the vibrations produced in the coke drum during a coke cutting operation;
filtering the measured vibrations to obtain the frequencies between 1000 and 2000 hertz;
displaying graphically said frequencies of interest; and
forming an audio display of the amplitude of said frequencies whereby said operator can observe the graphic display and listen to the audio display during the coke cutting operation.
