【 摘 要 】

This paper presents the summary of the work performed over the last decade, at IIT Bombay by the UCG group. The overall objective is to determine the feasibility of a given coal for underground coal gasification and then determine the capacity of a single pair of well through modelling and simulation. It would help one to design a UCG facility for the desired rate of gas production. The simulator developed in this study seeks inputs on four important aspects: Kinetics of all the reactions under the conditions of interest, heat and mass transfer limitations, if any, the flow patterns inside the cavity and lastly the thermo-mechanical failure of the coal. Each of them requires detailed studies in laboratory. Indian Lignite from one of the reserves was chosen as a case study.
