Module 1: Introduction to Combustion
  Lecture 4: Characterization of Solid Fuels
 
Various Combustion Modes
 
Premixed Flame
 :

Fuel and oxidizer are mixed before actual combustion.
Examples: Bunsen burner, LPG Stove


Diffusion Flame
 :

Fuel and oxidizer are mixed in the region where chemical reaction takes place.

 
Laminar and Turbulent Flames
 : Based on the flow characteristics; Turbulent flow occurs in practical combustion devices.
