3.5 tonns of coal is required for producing 1 mw
As Much As I Need
how much electrical power can be provided by coal
Coal is a convenient, low cost fuel. However, coal is also dirty, producing air borne particulate matter and numerous dangerous compounds. Acid rain is a result of the burning of high sulfur coal. Coal often contains heavy metals that are extremely hazardous to life. New generation coal fired power plants are much cleaner, but very expensive and rarely required by environmental laws in the US.
The Titanic had 159 coal-burning furnaces fueling the boilers.
No. Much of their power comes from coal.
an all nighter
2cans haha
it depends on how big the power station is
Yes,once its used as much oil and coal power station
There are more coal plants than solar plants because the cost per Mega-Watt is much less using coal than solar power, and currently coal is more efficient. The problem today is that in a environmentally conscious society coal is a 'dirty' fuel, and solar power is clean. That is why environmentalists are pushing for more Solar (and wind) power generation.
The energy density of coal can also be expressed in kilowatt-hours for some unit of mass, the units that electricity is most commonly sold in, to estimate how much coal is required to power electrical appliances. One kilowatt-hour is 3.6 MJ, so the energy density of coal is 6.67 kW·h/kg. The typical thermodynamic efficiency of coal power plants is about 30%, so of the 6.67 kW·h of energy per kilogram of coal, 30% of that-2.0 kW·h/kg-can successfully be turned into electricity; the rest is waste heat. So coal power plants obtain approximately 2.0 kW·h per kilogram of burned coal. I copied it from wiki page see the same for clear view http://en.wikipedia.org/wiki/Coal regards Raghs
