An information system for visualization of Underground Coal Gasification (UCG) has been developed. The main goal for the system is to provide means for better understanding and control of the process. The system uses mainly data generated during UCG process numerical simulation. Apart from that, the system is capable of storing and visualizing measurement georadar data, gathered during in-situ ...

Although coal mining has played a substantial role in world’s development as critical fuel source for at least 25 years, its value is partly offset by the massive environmental issues it presents during combustion. The shift to net-zero CO 2 emission will open unique possibilities new technological models which progressive studies and policies, development, modernization play significant role. ...

The Wabash River Coal Gasification Repowering Project (WRCGRP), a joint venture between Dynegy Power Corp., and PSI Energy, Inc., began commercial operation in November of 1995. The Project, selected by the United States Department of Energy (DOE) under the Clean Coal Program (Round IV) represents the largest operating coal-gasification combined-cycle plant in the world. This demonstration proj...
