The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a predetermined size in order to increase the surface area of the coal. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.

1. Background and Motivation The total US CO2 emissions for 2006 were 5934 million metric tons (Mt). Of this, the electricity sector was responsible for 2344 Mt (%). Coalfired power plants produced 83% of the electricity sector's CO2 emissions, with most of the remaining emissions from natural gasfired power plants (EIA, 2007).

For all of 2024, our estimated cost of natural gasfired electricity averages 32/MWh compared with an average 29/MWh for coal. We expect these similar costs will keep the share of generation from coal near 15% on average in 2024. Coal inventories. We forecast that coal inventories held by the electric power sector will reach almost 150 ...
