Research on Upgrading of Low Temperature Coke by Air Blowing in Operating CDQ

Abstract

One of the targets in the SCOPE21 process was to enhance the productivity of coke ovens. For the high productivity, it was investigated to push the coke at a low temperature and to upgrade the low temperature coke by reheating in a CDQ. The coke reheating in this research, reheating of coke by air blowing was tested in an operating CDQ and some useful data were obtained by measurement probe. A three dimensional simulation model was developed based on those data, and this model could simulate the conditions of CDQ and upgrading effect of coke precisely.
