Question

Toppr Admin · Accepted Answer

During combustion of gaseous fuels- deficiency of air lengthens the flame- When combustion is carried out in limited supply of air- the combustion is incomplete- The products of combustion remain unburnt and contaminate the smoke with particulate matter- Hence- the length of the flame increases-

During combustion of gaseous fuels, deficiency of air ___________.
Lengthens the flame.
Does not affect the flame length.
Tends to shorten the flame.
Increases the flame temperature.
