What is the heat content of coal in mmbtu per ton?
Anthracite 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. Bituminous 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. Subbituminous 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 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.

People do die in heat waves and global warming is real, but it is not possible to attribute any one extreme weather event to global warming and therefore it is not possible to say how many have died from this cause and because of global warming. The world currently produces around 30 billion metric… tons of carbon dioxide just from burning fossil fuels. In other words, several metric tons for every man, woman and child in the world. No matter how many deaths from heatstroke can be attributed directly to global warming, the number is too small to relate to tons of carbon emissions. In any case, many more deaths have occurred due to floods, hurricanes, tornadoes and other extreme weather events, some of which may have been caused or accentuated by global warming. (MORE)
1 Ton(2000lbs) coal is appox 40 cubic feet this varies by the character of the coal and the honesty of the weight
MMBTU is an acronym for "Million Metric British Thermal Units." The M's represent the Roman numeral for one thousand. One thousand thousands equal one million, thus MMBTU, not "Million Metric"
What is the energy equivalent in tons of coal for operating a radio for 4 years when a radio uses the energy equivalent of one twentieths of coal per year?
What is the energy equivalent in tons of coal for operating a radio for 4 years when a radio uses the energy equivalent of one twentieths of coal per year?. First look at the 1/20 ton then invert the 1/4 to get 4/1 then multiply to get the answer of 1/5.. 1/ 20 * 4/ 1 =1/ 5
fifoenergy.com says 35.314 cubic feet per 1 ton of bituminous coal.. My coal supplier tells me to figure about 36 cubic feet for my antrhacite pea coal. wikianswers says about 40 cubic feet per ton of antrhacite.
It compacts and increases as moisture and volatile hydrocarbons are driven off. Coal has a carbon content between 75 and 90 % , lignite (brown coal) hasn't completed the transformation and contains more moisture and nitrogen than bituminous or anthracite coals. Lignite has about 30 to 40% carbon con…tent. (MORE)

Depending on the quality; $70 to $400.00 per Lb. Wyoming coal is about $45 per Lb. If you're lucky enough to find a small piece of coal at least worth an ounce you can get up to $25 at your local pawn shop or jewelry sellers / buyers.
In 2011, the cost per ton per mile average was about $16.54. Thatwas with an index rating of about 128 compared to 1975.
China is the world's leading coal producer at 3,650 million tonnes per year since 1970. The United states and India follow closely with 930 and 610 million tonnes respectively.
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..

Coal has an energy value of 24 Megajoules/kg, which is the same as 6.67 kwh/kg. However a coal fired power plant will only have an efficiency of about 30 per cent so this reduces to 2.0 kwh/kg. Now when you say 1 ton, do you mean 2240 lb, 2000 lb, or 1000 kg (metric ton) ? I will assume 1000kg as… it makes the arithmetic easier, in fact 2.0 kwh/kg comes to 2000 kwh/metric ton. Note that kilowatt is a power, kilowatthour (kwh) is an amount of energy, which is what you wanted. If you want it for a short ton of 2000 lb, this will become 1814 kwh, and for a ton of 2240 lb it will be 2032 kwh (MORE)
\nIt depends on the form? Oxide? Wrought sheet or rod? Be assured it is changing daily. It is four times higher then it was less then a year ago. In wrought metal form it is 3-4 times higher then silver by the ounce.
It should be according to the quality of the gas, but roughly 1 metric Tonne = 48 MMBtu (Downey, M. 2010, Oil101) 1 metric Tonne = 48.7 MMBtu (Foss, M. 2007, Introduction to LNG , pag. 38,
In April 2010, gold was worth about $1,118.45 per troy ounce. Using that value, and about 14.583 troy ounces in a pound, one pound of gold is worth about $16,310.36. If you use the factor of 2,000 pounds per ton, then a ton of gold would be worth about $32,620,720.
According to Energy Information Administration (EIA) research, emissions range from 2,791 lbs per short ton for lignite coal to 5,685 lbs per short ton for anthracite coal. However, the coefficients for the coals that are primarily used in electricity production, bituminous and sub-bituminous are 4…,931 and 3,716 respectively. See the EIA related link for more information. (MORE)
\nBecause there is a vacuum between the inner and outer walls, heat cannot easily pass through from inside to outside - or from outside to inside.
It depends on the salt. There are many different salts than just NaCl. Basic stoiciomety can't solve it unless you give me an actual chemical formula.
Too many variables to answer- type of coal? Pickup or delivered? Where? Prices may range from $30-$65 per ton.
There are 32000 ounces per short ton US and 35840 ounces per long ton UK; as it was not mentioned witch tonnage so there is both.
Liquid water has more free moving atoms than frozen water. Liquid water has higher heat content than ice.
I think a Google search will help you with this one. Try: horse manure/btu or something like that.
The cost of coal varies from place to place. To determine that theprice for where you are, contact your local utility.
The internal heat of a system at constant pressure is calledenthalpy. A change in enthalpy can mean heat is released orabsorbed.
The price of metal are commodities and thus constantly changing. Asof August 01, 2014 the spot price per pound of Aluminium (Al)closed at . 87 $USD. One short ton (2000 pounds) thus equals a thenvalue of $1740.
It would be about the same as sand (0.8 kJ/kg.K) See Link for typicals for several materials.
200 billion / 2000 (that is the amount of pounds in a ton) = one hundred million
As a rule of thumb you would need about 138 Kg of coal (26GJ/Ton) to produce 1 ton of steam.
It could be either; but when you are talking about food, what is of interest is usually the energy content - meaning, chemical energy stored in the food. Heat IS energy, and a kilocalorie is the energy required to heat one kilogram of water by one degree Celsius.
2 tons No. A modern coal car carries 120 tons of coal. Some older onescarry 100 tons. On the B&O division of CSX, coal trains areusually 80 or 120 car unit trains. The length of the train isusually governed by the size of the originating or destinationyard.
Bauxite is worth about $20-60 per ton, depending on its contents. It is the most important aluminum ore. Ore that yields more aluminum has a greater value. Australia is the world's top producer of Bauxite, meeting almost a third of the world's requirements.
The residential heating oil industry is currently working to cut the sulfur content of heating oil and residential fuel oil from 1,500 parts per million to 15 parts per million by 2018. In addition to sulfur reduction, the heating oil industry is also working on new fuel blends called Bioheat which …contain between 2 and 20 percent renewable fuel. (MORE)
In a 'standard' domestic blender there could be a very small amount of heat produced by the friction of blades colliding with the food particles but it would be very minimal and probably indistingushable even after a considerable time especially if you are blending liquids. You might just notice a s…light rise in temperature if you just had dry ingredients such as coffee beans and ground them finely in a blender.

carbon Answer: 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 (MORE)
A metric ton is 1000 kg (2204.621 lbs). This is nearly equal to a long ton (old English measure for coal) of 2240 lbs. The English (US) short ton measure is 2000 lbs. If a bag is 40 kg then a metric ton would be 25 bags, a short ton a little more than 22 bags and a long ton a little more than 25 bag…s. (MORE)
Ummm, well it vary's by what manufacturer you get it from. If you get it from the world's biggest manufacturer in the world which is in Colorado it would cost approximately 200,000 a ton! Your Welcom. Follow me on twitter!! (:
None. The question is like asking how massive is a mile. A yard is a measure of distance, a tonne is a measure of mass. The two measure different things and one cannot be converted to the other.
as peat(90% moisture) is not regarded a rank of coal so lignite is the lowest grade of coal containing moisture as high as 30%.
The higher the carbon content, the better the quality of the coal. In any piece of coal, whatever isn't carbon is logically something else - usually sulfur compounds (that's pollution when the coal is burned).
Assuming that coal is essentially pure carbon, each 12 kg of coal will combust to form 44 kg of carbon dioxide (C+O 2 -->CO 2 ) a bit more than 3 times as much carbon dioxide as coal. A ton of carbon will burn to form about 3 tones of carbon dioxide.
No the coal will turn in to ashes and it is made to make long lasting fires.
At the end of 2008, Australia had 69,310 million metrictons of recoverable coal reserves, 8.9% of the world'stotal.
Assume you meant metric ton (tonne) = 1 000 kg (1 Tonne = 1 000 000 grams) In which case its the same value, eg 1 ppm = 1 gram / tonne.
Mass divided by time, where the mass is measured in tons and the time is measured in hours. If the mass and time are measured in other units they will need to be converted to tons and hours.
It doesn't phrased in that way. 1 ton of coal contains more carbonthan 1 ton of biomass by a large amount. Because of this it takesmore biomass to produce the same amount of power than a smalleramount of coal provides. This does not mean that biomass is worsefor the environment, as it will take mill…ions of years for thecarbon contained in coal to 'become coal' again, while it will onlytake one growing season (in the case of energy crops), or 50-100years (in the case of wood forests), to 'become biomass' again.

1 ton = 2000 pounds Multiply the known dollars/pound x 2000 pounds/ton. For example, to convert 12.8 dollars/pound into dollars/ton, do the following: 12.8 dollars/pound x 2000 pounds/ton = 25600 dollars/ton.
You may be able to purchase industrial diamonds by the ton, andcertainly you would pay less for them than you would for agem-quality diamond. Recently, a blue diamond sold for aboutUS$4,000,000 per carat. Note: one carat equals 0.0000002 ton.
Answer 1 Low-volatile bituminous is having highest heating capacity (33412 KJ/Kg). Answer 2 Anthracite. Answer 3 The anthracite coal heat capacity is 29000 KJ/Kg that is less than Low-volatile bituminous. See link below.
Coal is usually not a very good conductor of heat, but it depends alot on the type of coal as to how poor a conductor it is. In a study done at the University of Oklahoma, conductivities of 55different types of US coals were measured at 22Â°C in thelaboratory. Their thermal conductivities ranged …from 0.22 to 0.55W/mÂ°K. Other, more limited studies get the same types of values. For comparison, air at room temperature and pressure (which isconsidered a pretty fair insulator) has a conductivity of about0.026 W/mÂ°K (about 1/10 of coal). Copper (which is considered areally good conductor) at the same conditions is around 360 W/mÂ°K(roughly 1000 times that of coal). By that comparison, coal would be considered a fairly poorconductor of heat. This is kind of interesting since graphite anddiamond (pure forms of carbon - which is what coal is mostly madeup of) are rather good conductors of heat. The difference is mostlydue to the fact that coal is not PURE carbon, that it has a fairlyheterogeneous structure (as opposed to crystalline), that it variesin how wet or dry it is, and that it may actually be somewhatporous.
