Coke (fuel) Wikipedia

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...

Coal Rank an overview | ScienceDirect Topics

Coal rank is a measure of coal maturity and is the most fundamental parameter that relates both to the coalification history and the utilisation potential of a coal. Figure shows the change in coal chemical and physical properties with rank from bituminous to anthracite coals (Teichmuller and Teichmuller, 1975).As the rank increases, the vitrinite reflectance, carbon content, and C/H ...

Coalwater slurry fuel Wikipedia

Belovo Novosibirsk project. In the late 1950s, the Soviet Union looked for new methods of using coal sludge for power generation. Coalwater slurry fuel was made in a ball mill which pulverised the coal or coal sludge. This was done near a coal mine in Belovo, coalwater slurry fuel was transported through a pipeline to Novosibirskaya TEC5, Novosibirsk, a distance of 262 km (163 mi).
