There are four major types (or “ranks”) of coal. Rank refers to steps in a slow, natural process called “coalification,” during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, 4. • A Steam Power Plant converts the heat energy of coal into electrical energy. Coal is burnt in a boiler which converts water into steam. The expansion of steam in turbine produces mechanical power which drives the alternator coupled to the turbine. Steam Power Plants contribute maximum to the generation of Power for any country.Steam power plants PPT SlideShare

Different Types of Power Plants Based on the Energy Sources. In its simplest form, a Power Plant, known also as a Power Station, is an industrial facility used to generate electricity. To generate power, an electrical power plant needs to have an energy source. One source of energy is from the burning of fossil fuels, such as coal, oil andBowl mills are employed to pulverize the precrushed raw coal to the required fineness before it is. admitted into the boiler furnace for combustion.

Coal mining was introduced in England in the 17th-18th century, and toward the 19th century, it was recognized as a major power source. The two World Wars, the first in 1914 and the second in 1937, adversely affected mining. Subsequently, coal was utilized to generate iron needed for weapons (OKD, 2016). Before the 20th century, its productionprocess of combustion. the furnace in medium and large size power plants. • Large quantities of fuel can be fed into the furnace. • By feeding coal at a uniform rate. • Stoker save labour of ash handling and are self-cleaning. • Stokers save coal and increase the efficiency of coal firing. furnace temperatures.Firing Systems in Power Plants PDF Mill (Grinding)
