Expt 7: Flame Spread over a Solid Fuel Surface
Process in Solid Fuel Combustion
The flame front generates heat and pyrolyzes the unburnt side of the solid fuel.
Pyrolysis is the process during which solid fuel undergoes thermal degradation in the absence of oxidizer.
Pyrolysis leads to flow of fuel vapour.
Followed by this, mixing of ambient air with the fuel vapour occurs.
Fuel-air mixture gets ignited, and thereby forming a self-sustained flame.
Flame propagates in the downward direction.
Flame Spread Rate
The length of the paper consumed per unit time by the flame is known as Flame Spread Rate (FSR).
As the flame front propagates in the downward direction, the solid furl surface regresses.
Flame Spread Rate (FSR):
