Therefore: Natural gas is a fossil fuel that is formed when layers of buried plants and animals are exposed to intense heat and pressure over millions of years. Some popular units for comparing energy include British thermal units (Btu), barrels of oil equivalent, metric tons of oil equivalent, metric tons of coal equivalent, and terajoules. For example, in Hungary, the heat value of natural gas has an average of 34.12 MJ/M3. It is approximately the energy needed to heat one pound of water by 1 degree Fahrenheit. For example, if your sample has 85% methane and 15% ethane, then its heat value would be approximately 1,030 BTUs per cubic foot (or 2,860 kilojoules per cubic meter). We don't save this data. Because energy used in different countries comes from different places, Btu content of fuels varies slightly from country to country. Heating values vary depending upon the source of the gas.

We differentiate between gross and net heating values: The gross or high heating value is the amount of heat produced by the complete combustion of a unit quantity of fuel. The heat value of natural gas is the amount of heat released when the gas is burned. The gross BTU figure represents the total heat released from burning a given type of fuel including any latent (hidden) heat due to vaporization. To calculate gross BTUs, simply multiply together the specific gravity and energy value figures without performing any further calculations.. The most common type of natural gas used in North America has a heat value of around 40 MJ/m. It also contains hydrogen sulfide and helium in a very little amount. 1 cubic foot of natural gas = 1,039 Btu. The heat value of natural gas depends on how effective the thermal energy coming from the natural gas is. The average gross heating value of natural gas is approximately 1,020 British thermal units per standard cubic foot (Btu/scf), usually varying from 950 to 1,050 Btu/scf. The net or lower heating value is obtained by. The LHV can be calculated using the following formula: The British Thermal Unit, or BTU, is an energy unit.

How to Make the Perfect Clove of Garlic:, This website uses cookies to improve your experience. The price is not set by the quantity of natural gas, but the quality and the heating value will determine how much an individual (or a country) will pay for this fuel. The main component that affects a fuels heating value is its carbon content. Net BTU = (0.504 x 0.000125) x 91000 = 4530BTU/gal. Cookies are only used in the browser to improve user experience. 1 MJ/m3 = 26.83 BTU/SCF (British thermal unit / cubic foot). Some of our calculators and applications let you save application data to your local computer. The heat content of natural gas might be different in various countries. 1 barrel of residual fuel oil = 6,287,000 Btu. This high energy content coupled with its clean burning nature makes natural gas an attractive choice as a boiler or furnace fuel. 1218 0 obj <>/Filter/FlateDecode/ID[<8B176F5595F3534592C77465809F5513><7ECE73F70DDBF2499313D7D7D6226EFA>]/Index[1203 26]/Info 1202 0 R/Length 79/Prev 190049/Root 1204 0 R/Size 1229/Type/XRef/W[1 2 1]>>stream ``l where: L L L is the latent heat. As stated above, the heating value increases approximately 750 Btu for each carbon added beyond methane. Moisture reduces the heating value because it takes up space in the molecule that could otherwise be used for combustible material. Once we know that, we can use a standard formula to determine the amount of heat released during combustion. All Rights Reserved BNP Media.

A British thermal unit (Btu) is a measure of the heat content of fuels or energy sources. The higher heating value (also known gross calorific value or gross energy) of a fuel is defined as the amount of heat released by a specified quantity (initially at 25C) once it is combusted and the products have returned to a temperature of 25C, which takes into account the latent heat of vaporization of water in the combustion products. o 1* \T Q USDEPARTMENTOFCOMMERCE NationalBureauofStandards Subscribe to feeds for updates on EIA products including Today in Energy and What's New. The lower heating value (also known as net calorific value) of a fuel is defined as the amount of heat released by combusting a specified quantity (initially at 25C) and returning the temperature of the combustion products to 150C, which assumes the latent heat of vaporization of water in the reaction products is not recovered. The heating value of a fuel is the amount of heat released during its combustion. Heating value is one of the key calculations in energy industry. Therefore, natural gas is an extremely flammable gas, which is odourless and colourless too. Barrels or gallons for liquid petroleum fuels (such as gasoline, diesel fuel, and jet fuel) and biofuels (ethanol and biodiesel), 1 barrel (b) of crude oil or petroleum products = 42 U.S. gallons, 1 barrel of (U.S.) dry measure = 3.29122 bushels or 4.2104 cubic feet, 1 barrel (42 gallons) of crude oil produced in the United States =, 1 gallon of finished motor gasoline (containing about 10% fuel ethanol by volume) =, 1 gallon of diesel fuel or heating oil (with sulfur content less than 15 parts per million) =, 1 gallon of heating oil (with sulfur content at 15 to 500 parts per million) =, 1 short ton (2,000 pounds) of coal (consumed by the electric power sector) =, 1.039 million Btu per thousand cubic feet.
