Question

what is fuel.what is calarofic value​

Answer 1

The calorific value of a fuel is the quantity of heat produced by its combustion - at constant pressure and under "normal" conditions (i.e. to 0oC and under a pressure of 1,013 mbar).

The combustion process generates water vapor and certain techniques may be used to recover the quantity of heat contained in this water vapor by condensing it.

The Higher Calorific Value (or Gross Calorific Value - GCV) suppose that the water of combustion is entirely condensed and that the heat contained in the water vapor is recovered.

The Lower Calorific Value (or Net Calorific Value - NCV) suppose that the products of combustion contains the water vapor and that the heat in the water vapor is not recovered.

Answer 2

Different Fuels have different calorific value for diesel it is 44800 for petrol it is 47300

Hydrogen has the highest calorific as 150000. The producer gas gives the least calorific value as 1200 .These calorific values are taken approximately
