All Rights Reserved. Biodiesel, renewable diesel, and other biofuels. Net BTU = (0.504 x 0.000125) x 91000 = 4530BTU/gal. The LHV, or lower heating value, takes into account the fact that some of the heat from combustion is used to vaporize water in the fuel. The lower heating value (LHV) or higher heating value (HHV) of a gas is an important consideration when selecting a gas engine or CHP plant. How to Calculate Heating Value of Natural Gas | Openlab Chemstation Intelligent Reporting, Find the composition of the natural gas by percentage, The typical composition of natural gas is approximately 85% methane, 10% ethane, 3% propane and 2% butane, Look up the heating value for each component in British Thermal Units per standard cubic foot (Btu/scf), The heating values for methane, ethane, propane and butane are respectively 1,031 Btu/scf, 1,075 Btu/scf, 1,265 Btu/sf and 2,488 Btu/sf, Multiply each components percentage by its heating value to find the total heating value of the natural gas sample, For example: 85% x 1,031 = 876 + 10% x 1,075 = 108 + 3% x 1 ,265 = 38 + 2% x 2 , 488 = 100 We don't collect information from our users. Liquefied petroleum gas (LPG): 46-51 MJ/kg, Hard black coal (IEA definition): 23.9 MJ/kg, and even the conditions of your home heating system. data. It is experimentally measured using an apparatus called a bomb calorimeter.

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. Natural gas has a high heating value, which makes it an efficient fuel for home heating and other uses. Btu = British thermal units; scf = standard cubic feet. !.R5N4S* % For most practical purposes, however, either value can be used to compare different fuels. 1 gallon of heating oil (with sulfur content at 15 to 500 parts per million) = 138,500 Btu. 1 short ton (2,000 pounds) of coal (consumed by the electric power sector) = 18,934,000 Btu. LHV(MJ/kg) = -428 + 3528*C + 2240*H 6320*O [1] hv = qp + qs qw For example, even tap water is colder in winter, so it takes more time to boil it.

It also contains hydrogen sulfide and helium in a very little amount. The higher the heating value, the more heat that is released. We would find that its specific gravity is 0.504 and its energy value per gallon is 91,000BTUs/gal . Read More. Natural gas is a fossil fuel that consists primarily of methane, with small amounts of other hydrocarbons such as ethane and propane. Generally speaking, natural gas is composed of the following components which are typical but can vary greatly: Ethane 5% Nitrogen 2.5% Carbon Dioxide 1% Propane 1% Isobutane 0.3% n-Butane 0.3% Neopentane 0.1% Heating value is a quantitative measure of heat content of a natural gas. The GHV takes into account all of the heat released, including the latent heat of vaporization from water in the products of combustion.

We'll assume you're ok with this, but you can opt-out if you wish. We can calculate the heating value . As time goes on, people will start to recognize that the heating value of natural gas is decreasing. When it comes to understanding your energy consumption, the first step is knowing how to calculate heating value of natural gas. The main component that affects a fuels heating value is its carbon content. Common Units Common units for heating value: 1 Btu/lb = 2326.1 J/kg = 0.55556 kcal/kg 1 J/kg = 0.00043 Btu/lb = 2.39x10-4kcal/kg 1 kcal/kg = 1.80 Btu/lb = 4187 J/kg The British Thermal Unit, or BTU, is an energy unit. If you want read more standardized definition of the two above terminology Net calorific Value and Gross Calorific Value you can check the iso standards 6976. If your first bedroom is at least 120 square feet, you get to call your second bedroom a bedroom if it's at least 70 square feet with 7' on a side. ft.).
