[Stoves] venturi system -ratios of air and gas?

[Boll, Martin Dr.]

 A happy New Year to all stovers!

In a venturi system like of a propane gas-burner the driving gas has pressure about 30 to 50 millibar.
- What ratio have the volumes of gas and air, to make our admired blue flame, as it does in gas-flames?
-What ratio(range) must have air and woodgas , to get the same blue flame?

- I am aware different temperatures make a big difference in volume

Have all a great  98% "remaining rest" of the New Year!

P.S.
Simple questions have the tendency to afford complicated answers, sometimes (even often)
they exceed the capacity of the asking person.
