Coal fired power plant Energy Education The conversion of thiscoalto the end goal of electricity is a multi-facetedprocess: Thecoalmust be unloaded from the train. Traditional ways of doing this require the use of cranes picking up thecoalfrom the cars, however newerplantshave the floor underneath the train tracks drop away, allowing thecoalto be dropped into underground containment.

Typical Process Flow Diagram of IGCC plant -

As shown in the process flow diagram, the coal is first slurried with water and fed to the first stage of the gasifier. Oxygen with a purity of 95% is provided from the Air Separation Unit (ASU) and the coal is partially combusted to maintain a temperature of 1370 °C. Raw fuel gas is produced as the coal chemically reacts with oxygen and steam.

Coal Mining: How Is Coal Mined? - Science ABC

Most of the coal burned in power plants in the US are either bituminous or sub-bituminous. Coal Mining Process The US burned roughly 700 million tons of coal in 2016—enough to fill a standard railroad car every 4 seconds. 90% of that coal consumption went into the generation of electricity, while the rest (just 10%) was burned for other industrial/commercial requirements.
