Bituminous coal is a relatively hard coal containing a tarlike substance called bitumenIt is of higher quality than lignite coal but of poorer quality than anthracite coal Bituminous coal is an organic sedimentary rock formed by diagenetic and submetamorphic compression of peat bog material Bituminous coal has been compressed and heated so that its primary constituents 2011年1月3日 Concrete Aggregates Ian Sims, Bev Brown, in Lea's Chemistry of Cement and Concrete (Fourth Edition), 1998 Pulverisedfuel ash (pfa) Pulverised bituminous coal (pulverisedfuel) is burned at some electricity power stations, producing pulverisedfuel ash, about 20–25 per cent of which becomes fused together like clinker and is known as ‘furnacebottom ash’ SubBituminous Coal an overview ScienceDirect Topics2016年3月12日 Coal is an important energy source whose consumption increases continuously One of the many ways to use coal is coal blending, which is a very effective technique in power stations However, coal blending generates unsuspected problems, one of which is ash deposition that causes slagging and fouling In fact, most blends accelerate and generate heavier ash The effect of blending of bituminous and subbituminous coals Different coal types are all minerals and rocks made largely of carbonThis fossil fuel generates ~40% of the world's electricity and about 25% of the world's primary energyHowever, not all coal used is the same; it comes in different quantity levels of carbon—which dictates the quality of the coal Higher quality coal produces less smoke, burns longer, and provides more energy than Coal types Energy Education
