A 2000 MW power station could be handling coal in the range of 1600 tons/hr or around 12 million tons of coal annually. A single 500 MW unit consumes in the range of 400 tons/hr of coal. The coal input to the boiler of the power plant passes through three different phases before combustion in the boiler.
Anthracite also is the most brittle among coal types. When burned, it produces a very hot, blue flame. A shiny black rock, anthracite is used primarily for heating residential and commercial buildings in the northeastern region of Pennsylvania, where much of it is mined.
The different fuels that are burned include Coal, Pulverized Coal, Oil (typically # 2 or # 6 grade), Natural Gas, Waste Heat, or combinations of Oil and Gas. There are also steam boilers that heat the water by using the waste heat generated from another process in the plant to heat the water to create steam.
It can be stored anywhere and does not spoil. Coal is delivered in bulk, or can be purchased in 40 to 50 pound bags. However, bagged coal is more expensive than loose, or bulk, coal. When used in a boiler, Anthracite coal can heat your home as well as your entire water supply eliminating the need for a hot water heater.
Great pressure results in the creation of bituminous coal. Bituminous coal is commonly used in power plant boilers for generation of electric power. Bituminous coal has a higher boiler heating value than either sub-bituminous or lignite, but less than that of anthracite. Bituminous coal is mined chiefly in the Midwest and Appalachian regions.

Dec 11, 2017 · A boiler or a steam boiler in simple words is a device used to generate the steam at a desired pressure and temperature by transferring heat energy which is generally produced by burning fuel in order heat the water to change it to steam. The steam used in the boiler is used for external purposes i.e. electricity generation, heating or other
Coal was, however, used only on a limited scale until the early 18th century, when Abraham Darby of England and others developed methods of using in blast furnaces and forges coke made from coal. Successive metallurgical and engineering developments—most notably the invention of the coal-burning steam engine by James Watt —engendered an
Old wood burning fireplaces may have been blocked off and coal stoves had been piped into the old chimney flues. Some buildings still have their original coal fired boiler or furnace, but it has been converted to fuel oil or gas. In many 19th century homes, an old abandoned chimney used to serve a coal cooking range in the original kitchen.

Coal, for instance, is a common boiler fuel. It can even be distinguished further between lumps of coal and crushed coal, with the latter kind burning more efficiently in most cases. Of course, we know that coal isn’t always the cleanest of fuels, although it has its advantages at times and remains a common source of energy for boilers.
The steam boiler is an old convection heating technology dating back over 200 years and is most commonly found in old homes. Because steam boilers operate at a higher temperature than hot-water boilers, they are inherently less efficient than their hot-water cousins and are more finicky to operate.
