Non-recovery Coke Ovens for North-east Indian Coals: An Attempt for Energy Utilization
Demand for coke is on the rise and is predicted to go up further in the years to come. As on today, among the various commercially established coke making technologies, non-recovery/heat recovery ovens are established to be the sustainable ones. It has been investigated that the north eastern region (NER) of India has a number of coke ovens which are non recovery types and without heat recovery systems. Huge volume of coke oven gases released from these ovens which have high calorific values and contribute to major environmental degradation. In this paper, an attempt has been made for maximum utilization of these coke oven gases (COG) for heat recovery. The modern heat recovery ovens which are environmentally sustainable and have ease in operation have minimized the stringent environmental issues. This non-recovery/heat recovery coke making technology developed for high sulphur, high volatile coals of NER India for caking coals will be a promising technology for future, particularly in developing countries that are facing power and coke shortages.
