Which fuel has calorific value?
Which fuel has calorific value?
The calorific value of a fuel is the quantity of heat produced by its combustion – at constant pressure and under “normal” (standard) conditions (i.e. to 0oC and under a pressure of 1,013 mbar)….Fuel Calorific Values.
| Natural gas | 12500 kcal/kg |
|---|---|
| Fuel oil | 9520 kcal/kg |
| Brown coal | 3500 kcal/kg |
| Woods | 2500 kcal/kg |
| Electricity | 860 kcal/kWh |

Which coal has highest calorific value?
Anthracite
1 Anthracite. Anthracite (“coal-like”) is a hard, very low content of volatile compact variety of coal that has a high luster. It has the highest carbon content (between 92.1% and 98%), the fewest impurities, and the highest calorific content of all types of coal, which also includes bituminous coal and lignite.
Which product has more calorific value?
Calorific value is nothing but the energy contained in a fuel or food, determined by measuring the heat produced by the complete combustion of a specified quantity of it. This is now usually expressed in joules per kilogram. Hence, hydrogen has the highest calorific value.
What is the good fuel?
It should be high in its calorific value. Good fuels should be easy to store, leaving behind ash after being burnt and quickly combust. They should be inexpensive, readily available and do not emit any harmful smell while burning. Also it should be easily carried and regulated.
Which is the highest grade coal?
Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter.
What are the 4 grades of coal?
Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite.
Which is the fuel with the highest calorific value?
Hydrogen gas has the highest calorific value of 150 KJ/g among all the fuels. So, hydrogen gas is considered to be an extremely good fuel. However, hydrogen gas is not used as a fuel in homes and industries.
Which is the highest energy fuel, petrol or diesel?
Benzene is C6H6. Alcohol is not a single thing, but let’s assume you mean ethyl alcohol, a common fuel, which is C2H5OH. Since the by products of oxidation are CO2 and H2O each with some energy from the oxidation, it is clear that Diesel combustion yields the highest energy. Petrol: 2*C8H18 + 25*O2 => 16*CO2 + 18*H2O.
What is the calorific value of kerosene oil?
So, the calorific value of kerosene oil is 48 KJ/g. the calorific value of different types of fuels is given in following table. 1. 2. 3. 4. 5. 6.
How is energy content and calorific value calculated?
You can make ads in the Engineering ToolBox more useful to you! Energy content or calorific value is the same as the heat of combustion, and can be calculated from thermodynamical values, or measured in a suitable apparatus:
How to calculate the calorific value of fuel oil?
The quantity of heat evolved due to the combustion of sulphur is S × 9160 kJ. A fuel oil consists of 85% carbon, 12.5% hydrogen and the rest is incombustible material. Estimate the higher calorific value and the lower calorific value of this fuel, taking the specific enthalpy of the water vapour formed by combustion to be 2442 kJ/kg.
What makes a fuel have a lower calorific value?
Lower Calorific Value (= Net Calorific Value – NCV = Lower Heating Value – LHV) – the products of combustion contains the water vapor and the heat in the water vapor is not recovered The table below gives the gross and net heating value of fossil fuels as well as some alternative biobased fuels.
How is the calorific value of hydrogen determined?
For gaseous fuels the calorific value is expressed as kJ/m 3 measured at STP. Any fuel containing available hydrogen will form water vapour during the process of combustion.
How to calculate the GCV of a fuel?
For calculation of GCV of fuel we need to analysis of fuel and get the constituent of fuel on weight basis. Based on the enthalpy of formation we may estimate calorific value of fuel. Consider a fuel contains carbon, hydrogen, Nitrogen, sulphur, oxygen as 86.5%, 12%, 0.9%, 0.2%, 0.4% respectively,
