Question

make a list of any five fuels and calculate their calorific value. Also, find out their cost.​

Answer 1

Answer:

Fuel caloric value :

> The caloric value of a fuel is the quantity of heat produced by its combustion- at constant pressure under normal condition. i.e. zero degree celsius under a pressure of 1013 kcal / kg.

> Combustion process generate water and certain technique may be used to recover the quantity content in this water vapour condensing it .

i ). Higher caloric value - water of combustion is enternally condensed and the heat contained water vapour is recovered .

ii ). calorific value the product of combustion contain water vapour and dead heat in the water vapour is not recovered .

> Fuel calorific value :

1) natural gas. 12500 kcal / kg .

2) diesel. 10000. kcal / kg.

3) fuel oil. 9520. kcal / kg.

4) brown coal. 3500 kcal / kg.

5) woods. 2500 kcal / kg.

6) electricity. 800 kcal / kg.
