[Digestion] question about burning

[Duncan Martin]

Chris

The gas would still burn without mixed-in air - but the flame might be 
yellow, rather than barely visible blue. (If you did science at school, 
think of a Bunsen burner with the vent shut.)

How long has it been producing? An initial rush of CO2 is common, with only 
traces of methane (and maybe some H2). It might take some days or even weeks 
(depending on substrate) before CH4 becomes dominant.

Dear All,
this spring we have succeeded in building a gobar style plant in 
Transilvania.  It is now filled and producing gas.  However, we cannot get 
the gas to burn straight out of the unit.  I am assuming this is because 
there is no oxygen mixed with it.  Can anyone confirm this?  I would like to 
stop the head-scratching amongst the farming community.  Cheers,
Chris
