Power generation coal powered

With an estimated 400 years of coal available for future power generation, coal-powered steam turbines are expected to continue to dominate global electricity fuel markets. 

Electric Power Generation. Coal is the primary fuel for thermal electric power generation. Since 1940 the quantity of bituminous coal consumed by electric utilities has grown substantially in each successive decade, and this growth is expected to continue for many years. Coal consumed by electric utilities increased from about 536 x 10 t in 1981 to 689 x 10 t in 1989 (2). The reasons for increased coal demand include availability, relative stability of decreasing coal prices, and lack of problems with spent fuel disposal as experienced in nuclear power plants (see Nuclearreactors). 

CAFB [Chemically active fluidized-bed] A coal-gasification process intended for producing gas for power generation. Coal particles are injected into a shallow bed of lime particles that trap the sulfur dioxide. The bed particles are regenerated in a second fluidized bed, releasing the sulfur dioxide. Developed in the 1970s by the Esso Petroleum Company, UK, but not commercialized.

In addition to its widespread use in power generation, coal is also used for heat generation in residential settings across many countries, as too are liquid and gas-phase fossil fuels (Lighty et al. 2000). Such practices can affect ambient air quality, and Junninen et al. (2009) estimated that up to 58% of PMio concentrations measured in the Polish town of Zakopane were due to residential heating.

In the context of this chapter and electricity generation (power generation), coal plays a vital role worldwide. Coal-fired power plants currently fuel 41% of global electricity. In some countries, coal fuels a higher percentage of electricity. 

Data for the reference system—coal-fired electricity—are adapted from Loi et al. s study [46], the Ecoinvent database for rest of world (RoW) [47], technical reports of PECCI [42], and GIZ-GDE/MOIT s report [48], in combination with calculation results following the guidelines of the AustraHan National Greenhouse Accounts and the National Pollutant Inventory Emission estimation technique manual for Fossil Fuel Electric Power Generation [49,50]. Fig. 14.3 illustrates different processes of generating coal-fired electricity.

The importance of coal gasification as a means of produciag fuel gas(es) for iadustrial use caimot be underplayed. But coal gasification systems also have undesirable features. A range of undesirable products are also produced which must be removed before the products are used to provide fuel and/or to generate electric power (see Power generation) (22,41). 

Methanol, a clean burning fuel relative to conventional industrial fuels other than natural gas, can be used advantageously in stationary turbines and boilers because of its low flame luminosity and combustion temperature. Low NO emissions and virtually no sulfur or particulate emissions have been observed (83). Methanol is also considered for dual fuel (methanol plus oil or natural gas) combustion power boilers (84) as well as to fuel gas turbines in combined methanol / electric power production plants using coal gasification (85) (see Power generation).
