Numerical Simulation of Quenching Process in Coal Gasification

This Master’s Thesis compares two computational fluid dynamics solvers: the commercial solver ANSYS CFX and the open source code OpenFOAM. Simple benchmark cases with compressible and incompressible flows are tested and compared. Thereafter the more complex process of quenching in coal gasification is simulated. This thesis work describes the simulation of a part of the coal gasification proces...

UCGVision: Underground Coal Gasification Process Data Visualization Aspects

This work presents the UCGVision system designed for underground coal gasification process visualization, prediction, and monitoring. The possibility to visualize the ongoing reactions during the process is crucial for better insight into the process itself. Moreover, the system task is to give researchers and in the future process supervisor a tool to observe the current state of the process b...

Corrosion in coal gasification atmospheres

Corrosion of metallic materials by coal gasification atmospheres has been the subject of extensive study for over 20 years. While many alloys were found to be resistant to attack by high moisture content gases representative of fluidized bed gasifiers at temperatures up to 900 OC, good resistance could not be sustained for more than a few thousand hours as a result of changes in the structure a...
