Underground coal gasification (UCG) lab scale experimental results based pilot scale coal field designing and economical analysis

Underground coal gasification is a technique that has begun to develop in the first half of the 20th century, when demands for coal were high in energy production. Especially against the costs of extracting coal with low thermal value by conventional mining methods, it is anticipated as a method to gasify coal in underground conditions to obtain combustible gas. Basically, it is aimed to send oxygen gas, water vapor or air to the coal as a gasification agent through the wells that come down to the coal vein and to get combustible gases such as CO, H2 and CH4 from it by triggering gasification reactions.
