The calorific value of fuel, also known as its heating value, is the amount of energy released when a specific quantity of fuel is completely burned. It is usually expressed in units such as megajoules per kilogram (MJ/kg) or British thermal units per pound (BTU/lb). This value is crucial for determining the efficiency and energy output of fuels in various applications, including combustion engines and power generation. There are two main types: gross calorific value (including the heat of vaporization of water) and net calorific value (excluding it).
What else can I help you with?
Which fuel has highest calorific value and what is its calorific value?
hydrogen calorific value is 150000 kJ/kg
Which fuel has least calorific value and what is its calorific value?
Dung cakes. Its has a calorific value of 7 kilojoule.
What is the importance of the calorific value of a fuel?
The higher the calorific value of a fuel, the higher its combustion rate is, which is important knowledge to know. A low calorific value indicates more water vapor absorption.
Which fuel has the maximum calorific value?
hydrogen
Diesel calorific value?
The calorific value of fuel is the quantity of heat produced by its combustion at a constant pressure and under normal conditions. For diesel, the calorific value is 44,800.
How does calorific value helps to find out whether the fuel is good?
A good fuel is a fuel with a great calorific value; this fuel contain more energy in the unit of mass, it is more economic.
How do you convert gross calorific value to net calorific value?
You can convert gross calorific value (GCV) to net calorific value (NCV) by subtracting the latent heat of vaporization of water formed during combustion from GCV. The equation for this is NCV = GCV - 2.5 x (9 x % H2 - % O2), where % H2 is the percentage of hydrogen in the fuel and % O2 is the percentage of oxygen in the fuel.
What are the Importance of determining the calorific value of fuel?
nothig
Does temperature rise affect the calorific value of fuel?
no
What is the calorific value of sand?
Sand? burning in an engine? No. No. NO. Calorific value is the heat produced by burning fuel. Sand won't burn.
Does adding oxygen increase calorific value of fuels?
No. Oxygen is not a fuel, so it has no calorific value. Some people confuse "combustion" (burning a fuel) with "supports combustion" (allows burning to take place). Oxygen supports combustion, but does not burn itself. Therefore it has no calorific value.
What do you mean by calorific value of fuels and how can you determine the colorific value of solid liquid and gas?
calorific value means the total amount of heat energy evolved when 1gm of the fuel is completely burnt. from the combustion equation find out enthalpy of combustion.then divide the molecular weight to that quantity.
