Question

compare the fuel on basis of their calorific value in tabular form​

Answer 1

Explanation:

When fuels are burnt, heat is produced. The amount of heat produced by different types of fuels on burning is expressed in terms of calorific value. Calorific value of a fuel may be defined as the amount of heat produced on complete burning of 1 gm of fuel. S.I. unit of calorific value of fuels is kilojoule per gram (KJ/g). For example, when one gram of wood is burnt completely it produces 17 kilojoules heat. Therefore, the calorific value of wood is 17 KJ/g. in similar manner, when 1 gm of kerosene oil is burnt completely it produces 48 kilojoules heat. So, the calorific value of kerosene oil is 48 KJ/g. the calorific value of different types of fuels is given in following table.

Table of calorific value of fuels

Serial No. Fuel Calorific value

1. Hydrogen 150 KJ/g

2. Methane 55 KJ/g

3. LPG 50 KJ/g

4. Kerosene oil 48 KJ/g

5. Charcoal 33 KJ/g

6. Wood 17 KJ/
