Energy Density of Coal - The Physics Factbook

Coal has a relatively high energy density of approximately 24 MJ/kg. Energy density can be defined as the amount of energy per mass. Its SI units are J/kg but MJ/kg is more common. Eighty six percent of the coal burned in the United States is used by power plants to make energy for electricity.

Determination of the true density of pulverized coal samples

Determination of the true density of pulverized coal samples

The true density of a solid is calculated as the true unit volume of the solid exclusive of its pore space which is divided into the weight of the sample. The method is similar to that used to determine the density of refractory materials but the procedure is modified to yield precise density determinations of coal .

Fly ash - Wikipedia

Fly ash - Wikipedia

New fly ash production, i.e., the burning of coal, produces approximately 20 to 30 tons of CO 2 per ton of fly ash. Since the worldwide production of Portland cement is expected to reach nearly 2 billion tons by 2010, replacement of any large portion of this cement by fly ash could significantly reduce carbon emissions associated with construction, as long as the comparison takes the production of fly ash as .

Note 1) Diesel fuels are in USA broken up into 3 different classes: 1D, 2D and 4D.The difference between these classes depends on viscosity and boiling point ranges. 4D fuels tend to be used in low-speed engines.2D fuels are used in warmer weather and are sometimes mixed with 1D fuel to create a competent winter fuel.1D fuel is preferred for cold weather as it has a lower viscosity.
