Abstract
The Sesa Kembla Coke Company started operating its ovens in 1994 with technology from Kembla Coal and Coke Pty. Ltd., Australia, and has been continuously producing coke since then. Consequent to some shortcomings experienced in the initial installation, the alumina based fireclay bricks were redesigned in shapes and quality of refractory and arranged in a unique mosaic to suit the studied temperature profile and to ensure effective temperature resistance at a reduced cost. The new Sesa design was used to reconstruct the ovens in 1998 and the ovens have been operating satisfactorily since then with superior coke quality from a wide range of blended coals, a level of environmental pollution that is acceptable to the most stringent international standards, and with a high level of energy recovery from the exhaust gasses. In a further development experienced engineers from VeCon GmbH of Germany designed a compacted charging system to specifically adapt to the operation of these ovens. While the ovens were designed in Germany, detailing and manufacture was done in India to save costs. This system could use up to 70% semi soft coals in the coal charge to significantly reduce coal blend costs. The design is now currently being offered internationally in standard cost effective modules of 300,000 T/A each and can be expanded in multiples of this to achieve higher capacities at better economies of scale.
