If there's a transition from ice to water, we're considering the latent heat of fusion, whereas for the phase change from a liquid into steam, it's the latent heat of vaporization. To calculate gross BTUs, simply multiply together the specific gravity and energy value figures without performing any further calculations.. Accept 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. 1.4.2 Firing Practices3-5 There are three major types of boilers used for natural gas combustion in commercial, industrial, and utility applications . However, since every gas company uses their own units of calculating your cost of gas, it is important that you provide the correct unit cost, to get an accurate estimate. All Rights Reserved. Net BTUs take into account the fact that some of the heat from burning fuel is used to vaporize water in the fuel itself (for example, in gasoline). However, the scale is not that wide: natural gas producers must meet a lot of quality criteria and parameters before exporting their product. Natural gas is a fossil fuel that consists primarily of methane, with small amounts of other hydrocarbons such as ethane and propane. Raw Shrimp: What Are They, and What Does It Mean? Natural gas has a high heating value, which makes it an efficient fuel for home heating and other uses. Welcome to the Hydrogen Analysis Resource Center. However, more energy can be extracted from the mixture if this water is condensed. Season factors also affect the feel of a decrease in heating value. Visit our updated, This website requires certain cookies to work and uses other cookies to help you have the best experience. Natural gas is composed of methane, which is a molecule that contains carbon and hydrogen atoms. Once we know that, we can use a standard formula to determine the amount of heat released during combustion.

U.S. How to Calculate Heating Value of Natural Gas, Infrared heaters energy use (costs, efficiency, W/sq. 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. To calculate the HHV or LHV of a fuel, we need to know its chemical composition. Heating value is one of the key calculations in energy industry. The HHV is higher than the LHV because it takes into account the latent heat of vaporization of water. 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.
