What is the calorific value of diesel in kcal kg?
10800 Kcal/kg
Calorific value decides the efficiency of an energy source per unit weight. The Typical Gross calorific value of Diesel or HSD is 10800 Kcal/kg.
What is the calorific value of biodiesel?
about 37.27 MJ/kg
The calorific value of biodiesel is about 37.27 MJ/kg. This is 9% lower than regular Number 2 petrodiesel. Variations in biodiesel energy density is more dependent on the feedstock used than the production process. Still, these variations are less than for petrodiesel.
What is the calorific value of 1 kg fuel?
The calorific value of a fuel is expressed in a unit called kilojoule per kg (kJ/kg). (b)The calorific value of LPG is 55000KJ/kg means 1 kilogram of LPG is burned completely and55000KJ/kg of heat energy is produced.
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 |
|---|---|
| Propane-butane | 11950 kcal/kg |
| Disel | 10000 kcal/kg |
| Fuel oil | 9520 kcal/kg |
| Brown coal | 3500 kcal/kg |
How do you calculate calorific value of fuel?
Goutel suggested the following formula from calculating the higher calorific value when the percentage proximate analysis of fuel is known. The formula is, cal. value = 343.3 x fixed carbon % + α x % volatile matter kJ/kg.
Which fuel is the highest calorific value?
hydrogen
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 biofuel diesel?
Biodiesel is a renewable, biodegradable alternative fuel made from a mix of modified vegetable oils and diesel fuel. According to Edmunds, its production has increased from 25 million gallons in 2005 to 1.7 billion gallons in 2013. “Yellow grease” (used restaurant oil from cooking).
What is the calorific value of petrol and diesel?
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).
Which fuel is having highest calorific value?
The amount of heat energy produced by the complete combustion of 1 kilogram of a fuel is called its calorific value (when it is expressed in joule/kg). From the above table, we have observed that hydrogen has the highest calorific value.
How is calorific value calculated?
In this system, calories are not determined directly by burning the foods. Instead, the total caloric value is calculated by adding up the calories provided by the energy-containing nutrients: protein, carbohydrate, fat and alcohol.
What is calorific value of fuel class 8?
The amount of heat produced by the complete burning or combustion of 1Kilogram of a fuel is called its calorific value.
Which fuel has the maximum 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.
How to calculate a calorific value?
To calculate food calories, start by looking at how much protein, carbohydrates, and fat the food has. Then, multiply the total number of grams of protein by 4, since 1 gram of protein is equal to 4 calories. Do the same thing for the carbohydrates, since 1 gram of carbohydrates is equal to 4 calories.
What is the energy content of diesel fuel?
To calculate GGE and DGE, the energy content of one gallon of gasoline or diesel is divided by the energy content of the comparison fuel. For example, conventional gasoline has an energy content of 116,090 Btus per gallon, while propane has an energy content of 84,250 Btus per gallon.
What are the gross calorific values of fuel?
So the gross calorific value indicates how much energy can be released during the complete combustion of a given amount of fuel: It is comprised of the net calorific value plus the energy contained in the exhaust gases and in the water vapor produced during combustion.
