CFD Modelling of Underground Coal Gasification using ANSYS Fluent Simulator

Abstract

Underground Coal Gasification is a non-traditional, in-situ combustion process for converting coal into product gases. In this process coal is combusted and the produced syngas which basically contains CO2, H2, CO and CH4 is extracted to the surface with the help of drilled wells. In this study, with reference to a lab-scaled UCG experiment [1] and taking the experimental data as the basis for the research a two dimensional CFD reactor model was created and further studies were done to establish the activity at the different locations of the reactor.
