How a Coal Plant Works
How a Coal Plant Works. Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.
Coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and petrochemicals.This process is often known as "Coal to X" or "Carbon to X", where X can be many different hydrocarbon-based products. However, the most common process chain is "Coal …

A Mathematical Model of Coupled Gas Flow and Coal ...
· The common conceptual model applied to coal is that it is a dual-porosity reservoir, where gas is mostly stored in the coal matrix and Darcy fluid flow occurs in the natural fracture system (the contribution of flow in the coal matrix to Darcy flow can be neglected) (Purl et al. 1991; Pan and Connell 2012). The permeability of a coalbed is a ...
