coal fuel properties

Coal - Energy Education

Like all fossil fuels, coal emits carbon dioxide when it is burned. In fact, coal is responsible for more historical emissions of carbon dioxide than any other fuel. Additionally, most coal also contains large amounts of other elements, like sulfur, mercury, and sometimes lithium. [7] Burning coal also causes the formation of both NOx and SOx .

Properties and usage. Coke typically has a specific density between 1.85 and 1.9. It is highly porous. Since smoke-producing constituents are driven off during the coking of coal, coke forms a desirable fuel for stoves and furnaces in which conditions are not suitable for the complete burning of bituminous coal itself. Coke may be burned with little or no smoke under combustion conditions ...
