Abstract/Summary A steady state model is developed to estimate the gas production from Underground Coal Gasification (UCG) Process. This model features surface reactions of coal char with gasification medium to produce combustible gaseous product. This model predicts gas composition, temperature and gross calorific value of product gas across the gasification channel. Presented model is tested on different injection rates of gasification medium i.e. steam-oxygen, air and subsequently results were compared with field trial test data, conducted at Centralia, USA. The comparison indicates that present model gives reasonable predictions of the gas compositions at various air/steam injection ratios. Copyright
