What is the flash point of HFO?
The flash point is always above 50 °C (122 °F) and the density is always higher than 0.900. In general, heavy fuel oil usually contains cracked residua, reduced crude or cracking coil heavy product which is mixed (cut back) to a specified viscosity with cracked gas oils and fractionator bottoms.
Which oil has the highest calorific value?
Hence, hydrogen has the highest calorific value….Fuels with calorific values:
- Hydrogen: 150 KJ/g.
- Methane: 55 KJ/g.
- LPG: 50 KJ/g.
- Kerosene oil:48 KJ/g.
- Charcoal: 33 KJ/g.
- Wood: 17 KJ/g.
What is the calorific value of a good fuel?
Calorific Value of Fuel
| Fuel | Calorific Value Of Fuel( Approximately) |
|---|---|
| Diesel | 45000 |
| kerosene | 45000 |
| Petrol | 45000 |
| Methane | 50000 |
What is calorific value of solid fuel?
The calorific value or the heat value of a solid, liquid or gaseous fuel is defined as the number of heat units developed by the complete combustion of unit mass or unit normal volume of a given fuel. It may be expressed as kJ/kg or kJ/normal m3.
What HFO means?
The generic term heavy fuel oil (HFO) describes fuels used to generate motion and/or fuels to generate heat that have a particularly high viscosity and density.
Which Wood has highest calorific value?
The experimental values of the highest calorific value in terms of BDH are (mJ/kg): 19.40… 21.20 – for wood with natural bark content; 18.9…23.6 – for bark; 20.8±0,5 – for coniferous species (including pine – 20.90±0.30); 20.0±0.7 – for hardwood (including alder and aspen – 19.90±1.00; for birch bark – 23.6).
What is calorific value of diesel?
roughly 45.5 MJ/kg
The calorific value of diesel fuel is roughly 45.5 MJ/kg (megajoules per kilogram), slightly lower than petrol which is 45.8 MJ/kg. However, diesel fuel is denser than petrol and contains about 15% more energy by volume (roughly 36.9 MJ/litre compared to 33.7 MJ/litre).
What are the two types of calorific value?
Calorific value formula and types of calorific value
- There are two types of calorific value. Higher calorific value ( HCV )
- Higher calorific value or Gross calorific value. When 1 kg of fuel is burned, product of combustion is cooled down to room temperature.
- Lower calorific value or Net calorific value.
How is calorific value calculated?
Procedure to Calculate Calorific Value Net Calorific Value (NCV) means lower heating value (LHV) i.e. lower calorific value (LCV) is determined by the subtraction of heat of vaporization of the water vapour from the higher heating value. Latent heat corresponding to the partial pressure of water vapour in Kcal/kg.
Which wood has highest calorific value?
What is the heat value of fuel oil?
The heat or combustion value of a fuel oil can be expressed as the quantity of heat (Btu per gallon) released during the combustion process where the oxygen from the air reacts with the hydrogen and carbon in the fuel. Combustion or heating values for some common fuels oil grades: 1 Btu/US gal = 278.7 J/liter.
What is the calorific value of diesel oil?
Heavy oil has a calorific value of 11,000 kcal per kg. Diesel oil has a calorific value of 11,000 kcal per kg. Petrol oil has a calorific value of 11,110 kcal per kg. Natural gas has a calorific value of 560 kcal per cubic metres.
What is the density of heavy fuel oil?
In the MARPOL Marine Convention of 1973, heavy fuel oil is defined either by a density of greater than 900 kg/m³ at 15°C or a kinematic viscosity of more than 180 mm²/s at 50°C.
Which is fuel has a higher calorie value?
