How many forms of coal are there?
Coal is classified into four general categories, or "ranks." They range from lignite through sub-bituminous and bituminous to anthracite, reflecting the progression of individual deposits of coal to increasing heat and pressure. Anthracite coal has the highest carbon content, frequently associated with home heating. Bituminous coal is the most plentiful form of coal in the United States, and is used primarily to generate electricity and make coke for the steel industry. Sub-bituminous coal ranks below bituminous. This coal generally has a lower sulfur content than other types, which makes it attractive for use because it is cleaner burning. Lignite coal is a geologically young coal which has the lowest carbon content, 25-35 percent. Sometimes called brown coal, it is mainly used for electric power generation. Hope it helped :)
What is the purpose of coal?
coal is used for fires,heat,and etc.
What can a burning coal do for a power palnt?
burning coal releases heat, and that heat turns a turbine, which generates electricity.
Combustion of coal give out heat?
Yes, the combustion of coal (oxydation reaction) is an exothermic reaction, releasing heat.
How is coal energy stored?
the coal is designed to absorb heat at when heat hits it it stores that heat ++++ No. The energy is stored by coal simply being a combustible material, so it contains potential chemical energy.
What is the heat content of coal in mmbtu per ton?
Anthracite is coal with the highest carbon content, between 86 and 98 percent, and a heat value of nearly 15,000 BTUs-per-pound. Most frequently associated with home heating, anthracite is a very small segment of the U.S. coal market. There are 7.3 billion tons of anthracite reserves in the United States, found mostly in 11 northeastern counties in Pennsylvania. The most plentiful form of coal in the United States, bituminous coal is used primarily to generate electricity and make coke for the steel industry. The fastest growing market for coal, though still a small one, is supplying heat for industrial processes. Bituminous coal has a carbon content ranging from 45 to 86 percent carbon and a heat value of 10,500 to 15,500 BTUs-per-pound. Ranking below bituminous is subbituminous coal with 35-45 percent carbon content and a heat value between 8,300 and 13,000 BTUs-per-pound. Reserves are located mainly in a half-dozen Western states and Alaska. Although its heat value is lower, this coal generally has a lower sulfur content than other types, which makes it attractive for use because it is cleaner burning. Lignite is a geologically young coal which has the lowest carbon content, 25-35 percent, and a heat value ranging between 4,000 and 8,300 BTUs-per-pound. Sometimes called brown coal, it is mainly used for electric power generation.
How many BTU per ton of coal?
20 Million BTU ****************** The heat content of coal varies. Bituminous coal typically has a gross heating value of 30,600,000 BTU per ton. The net heating value is 26,000,000 BTU per ton, assuming 85% efficiency. If you need more precise information, go to the U.S. Department of Energy website at www.doe.gov and search on the heat content of coal. -ecn
How do you calculate coal usage to produce 1 MW power?
First in order to calculate the heat content of a particular type of coal, an ultimate analysis must be done. Then the combustion efficiency of the coal must be calculated, the boiler efficiency is then determined by a boiler "acceptance test", or heat balance. The steam is then run through an engine driving a generator to determine the total plant efficiency thus determining how much coal is burned to produce a set amount of electricity. Several publications on Steam power plant operation explain these efficiency tests in more detail.
What element content is coal graded by?
carbonAnswer:While coal's fixed carbon content ( not associated with volatile carbon content )is graded for heat production and suitability for metallurgical use. it is also graded by its sulfur content to to determine its acidity (this affects stack gas treatment). Coal analysis also include hydrogen, oxygen and nitrogen. Uranium analysis is sometimes included for specific pollution or emission relatd studies.Non-elemental anays includes ash (inorganic) and water content
Why is coal important to kentucky?
Because it is the primary fuel used to heat oil for frying chicken.
Does coal heat homes?
It can in coal/wood stoves.

What is the difference between GCV and UHV?
Useful heat value(UHV) pricing mechanism of coal deducted ash and moisture content from standard formula and in this coal is categorised into 7 grades. Gross calorific value(GCV) of coal has 17 grades and prices are linked to the actual calorific value/quality of coal-by latika joshi
How does coal get its power?
By heat
