Nov 17, 2012· coal mill/pulverizer in thermal power plants shivaji choudhury 2. Coal continues to play a predominant role in the production of electricity in the world, A very large percentage of the total coal is burned in pulverized form. Pulverized coal achieved its first commercial success in the cement industry.

The basic thermodynamic cycle of a steam power plant is the Rankine cycle, in which the thermal fluid is water circulating through the circuit, changing its phase as it passes through the different stages. The highpressure steam is generated from water, generally using fossil fuels, such as natural gas, fuel oil, or even gasified coal.

Coalfired power plants. According to World Coal Association, coalfired power plants currently account for 41% of global electricity, with almost half of that coming from China alone. Coalfired power plants use steam coal as source to generate electricity and consequently emit a significant amount of harmful gases into the atmosphere.

The Future of Coal • Although the COE for IGCC is lower for Bituminous coal, differences narrow for lower rank coals and at elevation; cost improvements for PC could further narrow the gap. Also, Oxyfuel PC looks competitive. • It is too early to pick winners for coalbased power generation with capture.
