The characterization of coal quality from the Jining coalfield

Composition and quality of coals in the Huaibei Coalfield, Anhui, China

“…In fact, some of these environmental problems could be reduced if coal quality information is available and adequate clean coal technologies are used. Therefore, information about the characteristics of chemical properties, such as minerals and trace elements in coals, are urgently needed for coal utilization in an environmentally acceptable manner (Finkelman and Gross, 1999;Liu et al, 2003Liu et al, , 2005a.…”

Gas/particle flow and combustion characteristics and NOx emissions of a new swirl coal burner

“…Coal is the most abundant reserves fossil fuel in the world, and the absolute amount of coal in average annual consumption will show an upward trend, especially in China [1]. Owing to relative plentiful supply and low price of coal, many countries in the world use coal as fuel for power generation, particularly adopt the pulverized coal boiler [2e5].…”

Geochemistry of Trace Elements as one of the Important Coal Quality Parameter: An Example from Balingian Coal, Malaysia

“…The organically and associated trace elements tend to be vaporized, either escaping to the atmosphere or are adsorbed on the fine fly ash particles upon combustion in the furnace. The inorganically associated elements are generally non-volatile or have very low volatility and tend to be retained in the bottom ash and in the fly ash particles upon combustion (Dai et al 2010;Finkelman 1994;Huang et al 2004;Liu et al 2005Liu et al , 2004Querol et al 1995;Spears & Zheng 1999;Vassilev & Braekman-Danheux 1999;Vejahati et al 2010), though partitioning of trace elements also depends on the natural volatility of these elements (Clarke & Sloss 1992;Miller 2011;Querol et al 1995;Suárez-Ruiz & Ward 2008;Vejahati et al 2010). …”
