Laboratory-Scale Integrated Coke Dry Quenching System for Coal Carbonization Test

Abstract

Carbonization test using pilot coke oven is an important laboratory-scale analysis to evaluate coke-making ability of metallurgical coals. RDCIS, SAIL, comprises a pilot oven of 250 kg coal charging capacity, with the facility of both top and stamp chargings. The functional pilot coke oven of this size for carbonization test is expensive and requires a large number of samples and time. To prevail over these limitations, a small-scale carbonization equipment was designed and developed in RDCIS. Experiments were conducted in both standard pilot ovens and newly developed carbonizations test equipment, namely integrated dry quenching system, and results were compared. Strong correlations were found between test results obtained from both the apparatus. This paper expatiates the basic outline of the equipment, basis of design, and results obtained from the carbonization tests using this equipment.
