Coal Properties and System Operating Parameters for Underground Coal Gasification
TL;DR: In this article, the influence of the properties for gasification agent and gasification methods on underground coal gasifier performance were studied through a model experiment for underground coal coal gasification, and the results showed that pulsating gasification to some extent could improve gas quality, whereas steam gasification led to the production of high heating value gas.

Numerical simulation on three-dimensional nonlinear and unstable seepage of fluid in underground coal gasification
TL;DR: In this paper, the authors studied the nonlinear seepage movement characteristics of fluid in underground coal gasification (UCG) and established mathematical models of three-dimensional unstable and nonlinear SE. Solution to the mathematical models is made through the finite element method.

Three-dimensional non-linear numerical analysis on the oxygen concentration field in underground coal gasification
TL;DR: In this article, the 3D non-linear unstable mathematical models on the convection diffusion for oxygen are established and the determination method of the major model parameters is explained, in order to curb such pseudo-physical effects as numerical oscillation and surfeit frequently occurred in the solution of the complex mathematical models, the novel finite unit algorithm is adopted to solve the numerical models established.
