The Morgantown Energy Research Center (MERC) is conducting a combined program of field tests, laboratory experiments and mathematical modeling on the subject of underground coal gsification. An Underground Coal Conversion Simulation Laboratory was constructed and a total of nineteen tests have been conducted to investigate, qualitatively and quantitatively, ignition, carbonization, and gasification phenomena of the Longwall Generator (LWG) concept. The LWG concept is specifically designed for use in thin seams of eastern bituminous coals. This report describes the analyses and interpretations of the experimental data collected in the Underground Coal Gasification Simulation Laboratory at the Morgantown Energy Research Center. The objective of this study is to identify and quantify parametric relationships in the test results through a well-organized effot of modeling and correlation to help guide field tests and plan future laboratory simulation experiments.
