[Stoves] basics: Need different flame-speeds different mixture-procedures?

[Jeff Davis]

Dear Martin,

Town gas was much like woodgas:

I have burned woodgas in my burner with premix and no premix. I think that the 
H2 helps to keep the flame lit.

Forced secondary air helps to keep the flame lit on windy days.

Forced secondary air is noisy.


Best wishes,

Jeff
