Coal explained - U.S. Energy Information .Deze pagina vertalen

Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce. The rank of a coal deposit is determined by the amount of pressure and heat that acted on the plants over time.

ABSTRACT This study comprehensively investigated the emission characteristics of primary air pollutants (PM, SO2 and NOx) and trace elements (As, Cd, Cr, Hg and Pb) from twelve coal-fired industrial boilers, nine of which were ultra-low emission (ULE) and three of which were non-ULE, based on field measurements. The concentrations, release ratios and relative enrichment factors (REFs) of .

Aberthaw coal-fired power plant

Aberthaw was a coal-fired power plant located in Wales in the UK. With a capacity of around 1,560 MW it generated enough power to meet the needs of 1.5 million s. We invested in technologies to reduce emissions at Aberthaw, such as the Flue Gas Desulphurisation (FGD) technology, that reduces sulphur emissions by up to 95% and installed low NOx boiler technology to Unit 9 which reduced ...
