What is the lower heating value of diesel?
What is the lower heating value of diesel?
42-46 MJ/kg
Heat Values of Various Fuels
| Heat value | |
|---|---|
| Diesel fuel | 42-46 MJ/kg |
| Crude oil | 42-47 MJ/kg |
| Liquefied petroleum gas (LPG) | 46-51 MJ/kg |

How do you calculate LHV of fuel?
Under this formula, the relationship between the lower heating value of a fuel and the higher heating value of that fuel is: LHV = HHV – 10.55(W + 9H) Where: LHV = lower heating value of fuel in Btu/lb, HHV = higher heating value of fuel in Btu/lb, W = Weight % of moisture in fuel, and H = Weight % of hydrogen in fuel.
What is the calorific value of diesel oil?
The Typical Gross calorific value of Diesel or HSD is 10800 Kcal/kg.
What is LHV 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. The total amount of heat liberated during the combustion of a unit of fuel, the HHV or HCV, includes the latent heat stored in the vapourised water.
What is the difference between LHV and HHV?
HHV stands for higher heating value while LHV stands for lower heating value. The key difference between HHV and LHV is that HHV can be determined by bringing all the products of combustion back to the original pre-combustion temperature while allowing any produced vapour to condense.
What is the LHV of propane?
0.498
| Fuel | Density | Lower Heating Value (LHV) (Net Calorific Value – NCV) |
|---|---|---|
| @0°C/32°F, 1 bar | ||
| Pentane | 0.63 | 12.60 |
| Petroleum naphtha* | 0.725 | 12.47 |
| Propane | 0.498 | 12.88 |
What is the difference between HHV and LHV?
How do you calculate LHV of ch4?
Heating value of Methane We compute the lower heating value (LHV) as the difference in enthalpy (per kg mixture) between reactants and products at constant temperature and pressure, divided by the mass fraction of fuel in the reactants.
Which fuel has the highest BTU output by volume?
Why use British thermal units?
- Petroleum—6.63 billion barrels—32.23 quadrillion Btu.
- Natural gas—30.48 trillion cubic feet—31.54 quadrillion Btu.
- Coal—477.32 million short tons—9.18 quadrillion Btu.
What is the flash point of high speed diesel?
The flash point of High speed diesel is stipulated as min. 32 deg C and thus it falls under the category of class ‘B’ of petroleum products. While other diesel fuels have a flash point of min. 66 deg.
Should I use LHV or HHV?
1. The numerical difference between the LHV and HHV of a fuel is roughly equivalent to the amount of latent heat of vaporization that can be practically recovered in a secondary condenser per unit of fuel burned. The numerical value of HHV is always greater than or equal to the LHV.
Why is LHV used instead of HHV?
The key difference between HHV and LHV is that HHV can be determined by bringing all the products of combustion back to the original pre-combustion temperature while allowing any produced vapour to condense. Meanwhile, LHV can be determined by subtracting the heat of vaporization of water from the higher heating value.

What units are used to convert heating values to BTUs?
The heating values in units of MJ/kg, are converted from the heating values in units of Btu/lb. For solid fuels, the heating values in units of Btu/lb are converted from the heating values in units of Btu/ton.
What is 1 Megajoule/Kilogram in BTU/pound?
