Effect of Injection Flow Rate on Product Gas Quality in Underground Coal Gasification (UCG) Based on Laboratory Scale Experiment: Development of Co-Axial UCG System [PDF]
Energies, 2017 Underground coal gasification (UCG) is a technique to recover coal energy without mining by converting coal into a valuable gas. Model UCG experiments on a laboratory scale were carried out under a low flow rate (6~12 L/min) and a high flow rate (15~30 L/

Reservoir-Geomechanics of Underground Coal Gasification (UCG)
, 2016 The Underground Coal Gasification (UCG) is still not in a worldwide operation despite inheriting an old idea which is nearly one and a half century old. Aside from effects by other fuel sources on development of the UCG and from a technical perspective, this delay is due to the complex nature of the process.
