    Coal Gasification Combined Cycle Power Plant. In the coal gasification process, pulverized coal is air separated and gasified. The resulting gas is cleaned of particulates. A wet cleanup process removes impurities, particularly sulfur, a universal constituent of coal. The coal gas is then burned as a fuel in a gas turbine engine.

    coal is converted mostly to H2S,rather than S02'while nitrogen from coal is converted mostly to NH3 and almost no NO, is formed. It is on this basis that the technology is characterised as a clean coal technology. Depending upon the type of the gasifier and the operating conditions, coal gasification can produce a gas suitable for different uses.

    Gasification is a process that converts biomass- or fossil fuel-based carbonaceous materials into gases, including as the largest fractions: nitrogen (N2), carbon monoxide (CO), hydrogen (H2), and carbon dioxide (CO2). This is achieved by reacting the feedstock material at high temperatures (typically >700 °C), without combustion, via controlling the amount of oxygen and/or steam present in
