ANSWER TO QUESTIONS in Page 25:

1. How does flame height change for increase/decrease of primary aeration?




2. How does flame height change for increased jet flow rate?




They are directly proportional.



3. How does replacing methane with propane affect the burner design assuming the total burner
power remains the same?

This effect is generally known as the stoichiometry effect and the effect is as follows:




With the increase of flame length, all design factors will change like nozzle velocity, the fuel/air ratio
and other factors.

, 4. What is the effect of aeration with oxygen rather than air?




Note that replacing air with oxygen is essentially the same as increasing the mole ratio of oxygen from
around 0.21 (normal mole fraction of oxygen in air) to 1.00 (pure oxygen).
