Coal
Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
AGL Energy Loy Yang Mine Case Study
of coal an hour or over one tonne of coal a second. The coal is taken from the mine to the power station by 15 kilometres of conveyors that carry the coal at speeds of metres a second to an 80,000tonne capacity bunker. The coal is crushed by rotary crushers that can handle 2,500 tonnes an hour each before it is delivered to the power station.
The Efficiency of Power Plants of Different Types
27/05/2010 · The overall coal plant efficiency ranges from 32 % to 42 %. This is mainly dictated by the Superheat and Reheat steam temperatures and Superheat pressures. Most of the large power plants operate at steam pressures of 170 bar and 570 °C Superheat, and 570 ° C reheat temperatures. The efficiencies of these plants range from 35 % to 38 %.

UNIT1 THERMAL POWER STATIONS Introduction
The fuel ( coal) is cheaper. The cost of generation is lesser than that of diesel power plants. Disadvantages: It pollutes the atmosphere due to the production of large amount of smoke. This is one of the causes of global warming. The overall efficiency of a thermal power station is low (less than 30%).

Pulverized coal storage in Bunker and coal handing system
The coal received by the plant from the mine may vary widely in sizes. It is necessary to make the coal of uniform size before passing the pulverizer for efficient grinding. The coal received from the mine is passed through a preliminary crusher to reduce the size to allowable limit (30 mm).
Increasing the Efficiency of Existing CoalFired Power Plants
Increasing efficiency of coal plants may help to address these concerns by reducing emissions without reducing output. Additionally, Congress may want to consider whether such efficiency improvements could be accelerated if these were implemented in a program focused on increasing the efficiency of the coalfired power plant sector.
