Specific energy of coal
WebDifferent coal types are all minerals and rocks made largely of carbon. This fossil fuel generates ~40% of the world's electricity and about 25% of the world's primary energy. However, not all coal used is the same; it comes in different quantity levels of carbon—which dictates the quality of the coal. WebThermal conductivity of Bituminous Coal is 0.2 W/ (m·K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance’s ability to transfer heat through a material by conduction.
