Moisture reduces the heating value because it takes up space in the molecule that could otherwise be used for combustible material. Once you have done this for all of the elements, you can add up all of the results to get the total heating value for the fuel. Heating value is the number of British Thermal Units (BTUs) in one cubic foot of natural gas. All Rights Reserved. It is the amount of heat released by a fuel when it is burned, minus the amount of heat required to bring the product of combustion back to the initial temperature of the fuel and air. The higher the heating value, the more energy that is available for use. The heating value can be calculated using the following equation: hv = qp + qs - qw where: hv = Heating value (kJ/kg) qp = Heat of combustion at constant pressure (kJ/kg) qs = Heat of combustion at constant volume (kJ/kg) Find the gross or higher heating value of the fuel Copyright 2023. For most practical purposes, however, either value can be used to compare different fuels. Natural gas producers add odour to the gas to make it less dangerous and to make leaking more noticeable. LHV(MJ/kg) = -428 + 3528*C + 2240*H 6320*O [1] If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page.. As time goes on, people will start to recognize that the heating value of natural gas is decreasing. The most common fuels are fossil fuels, such as coal, oil and natural gas.

Natural gas is mostly methane (CH4), but it also contains small amounts of other gases like ethane (C2H6), propane (C3H8), butane (C4H10), and pentanes (C5H12). hb```6 ea.O+chXMY>vg\A> e2L4/O:4& It is approximately the energy needed to heat one pound of water by 1 degree Fahrenheit. The higher the heating value, the more energy the gas contains. Then enter the value you want to convert and its units, and clickConvertto initiate the conversion. Higher Heating Values mean that more energy can be extracted from a given quantity of natural gas, and this usually results in a higher price for the gas. Fuel Gases - Heating Values Combustion heat values for gases like acetylene, blast furnace gas, ethane, biogas and more - Gross and Net values. See Heat of combustion for examples of calculation of gross heating values from standard heat of formation of substances. This is because carbon-carbon bonds are very stable and require a lot of energy to break them apart.
