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.
The proof is 50 per cent of the alcohol content. 80 proof is 40% alcohol.
There are approximately 20 bushels in a ton of rice. This conversion can vary slightly based on the specific type of rice and its moisture content, but the general estimate is around 20 bushels per ton. A bushel of rice typically weighs about 45 pounds, making this conversion consistent for most rice varieties.
Aunt Jemima syrup, now known as Pearl Milling Company syrup, typically has a density of around 1.3 grams per milliliter (g/mL). This value can vary slightly based on the specific formulation and any added ingredients. Generally, syrups are denser than water due to their high sugar content.
Corn silage is typically measured in tons rather than bushels, but if you need to make a conversion, one ton of corn silage is roughly equivalent to about 8 to 10 bushels of corn. The exact conversion can vary depending on the moisture content and the specific type of corn. Generally, the conversion factor used is about 9 bushels per ton.

To obtain the number of grams of CO2 emitted per gallon of gasoline combusted, the heat content of the fuel per gallon is multiplied by the kg CO2 per heat content of the fuel. The average heat content per gallon of gasoline is 0.125 mmbtu/gallon and the average emissions per heat content of gasoline is 71.35 kg CO2/mmbtu.
Oh, dude, it's like this - to convert MMBtu to MCF, you need to know the heat content of the gas in Btu per cubic foot. Then you just divide the number of MMBtu by the heat content to get the equivalent in MCF. It's like converting apples to oranges, but with gas. Easy peasy, right?
The conversion from MMBtu (million British thermal units) to metric tons depends on the type of fuel being measured, as different fuels have varying energy content. For example, natural gas has an energy content of about 1,000 Btu per cubic foot, translating roughly to 0.027 metric tons per MMBtu. For coal, it can range from approximately 0.2 to 0.3 metric tons per MMBtu, depending on its grade. Thus, the exact conversion varies based on the specific fuel type.
The heat content of coal, measured in British thermal units (BTU) per pound, determines how much energy the coal can produce when burned. This is important in determining the efficiency and cost-effectiveness of using coal as a fuel source. Higher heat content coal can produce more energy per pound, making it more desirable for power generation and other industrial applications.
To convert from cubic feet to mmBTU (million British Thermal Units), you need to know the energy content of the gas being measured, typically expressed in BTU per cubic foot. The general conversion formula is: mmBTU = (cubic feet × BTU per cubic foot) / 1,000,000. For example, if the gas has an energy content of 1,000 BTU per cubic foot, then 1,000 cubic feet would equal 1 mmBTU. Always ensure to use the correct energy content value for accurate conversions.

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
On average, coal has an energy content of about 24,000,000 joules per kilogram. This energy content can vary depending on the type and quality of the coal.
The energy released by burning coal comes from the combustion of carbon in the coal. This process generates heat energy, which is released in the form of thermal energy and light. The energy content of coal is typically measured in British thermal units (BTUs) or joules per unit of mass.
Anthracite coal typically gives off more energy than bituminous coal because it has a higher carbon content and burns more efficiently. This means that anthracite coal produces more heat per unit of weight when burned.
Anthracite coal has a heating value of about 25 million Btu per ton. It is a high-quality coal with a high carbon content and low moisture content, making it a popular choice for heating and energy generation.
The sulfur content of coal and its heating values are not constant across all grades of coal. It would require information of type of coal, carbon content, sulfur content and ash content to even start the calculation.
