Aug 23 2015 Coal is not a single homogenous material. There are dozens of different types of coal depending upon how it was formed from what materials and how much pressure it was subjected to. Consequently it has a range of densities from 0.83 gml i.e. less that that of water to 1.5 gml i.e. 50 more dense than water.

Coal classification any of various ways in which coal is grouped. Most classifications are based on the results of chemical analyses and physical tests but some are more empirical in nature. Coal classifications are important because they provide valuable information to commercial users e.g. for power generation and coke manufacturing and to researchers studying the origin of coal.

Coal History. Coal has been used as an energy source for nearly 2000 years. For example coal was widely used for home heating in early 17th century England. But the Industrial Revolution dramatically increased the demand for coal. Specifically James Watt's improvements to the steam engine made coal useful for doing work.By the 1830's coal mining was a booming industry in the eastern United ...
Coal is first milled to a fine powder which increases the surface area and allows it to burn more quickly. In these pulverised coal combustion PCC systems the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high temperature see diagram. The hot gases and heat energy produced converts water – in tubes ...

Coal’s most notorious byproduct is carbon dioxide CO2. Every million BTUs released from burning coal releases an average of 208 pounds of CO2 see note below. Since a ton of coal has 20.025 million BTUs that means it creates 4172 pounds of CO2 when it is burned. Running our 100-watt bulb for one year will produce 1670 pounds of CO2.
