Coal (from the Old English term col, which has meant "mineral of fossilized carbon" since the 13th century) is a combustible black or brownishblack sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to ...
Figure 1 shows the boiler efficiency with the GCV of the coal. As the coal used with higher GCV, efficiency is increased. Lignite coal with 4300 kcal/kg gives a % in this boiler, while semi bituminous coal with 5800 kcal/kg gives % efficiency in this boiler. So as the higher grade coal is used, efficiency will be increase.
