Module 1: Introduction to Combustion
  Lecture 2: What is Fuel and Oxidizer?
 

Determines the heating value of the gaseous fuel.
Fuel and air are burnt in a burner.
Cooling water in the water jacket-absorbs the heat released during combustion.
Heating value- calculated from the water flow rate and rise in temperature.
 
Liquid Fuels and Oxidizers
  • Liquid fuel is one of the major energy sources in the transport sector.
  • Crude oil is formed from organic sources, animals, vegetables – which are entrapped in rocks under high pressure and temperature for million years.
