If you floated some NaOH in a little boat on some water in a large container, and inverted a test tube of 'gas' over the top of it, as long as you kept the pressure constant (use plastic tube instead of testtube with a rubber diaphragm at the top , so you can use the diaphragm as a pressure gauge), you could maybe work out the ratio of methane to CO2. With a bit of lateral thinking, you could probably device a much more robust experiment

I have a feeling my project is about hit the buffers. Do you think, scaled up, this digester idea is really worth it if it involves lots of complicated stuff to get it clean and concentrated enough to use. You guys appear to have been at it a long time so I guess you know the truth by now.  |

cant help with the detail as I have never attempted biogas production,but it would appear that you are doing most things right,and 'almost there' In your position I would be tempted to give it at least 6 months,carefully recording any changes you make;remember,we are talking biology here,which tends to be rather more fickle than pure chemistry! Keep it going,then invite the forum to a waste fuelled barbeque in the spring lol  |

JMALW Dont give up  as NI says you are almost there, as long as we can make some progress without spending too much of your money ev3en a negative result is valuable. Think of the vast amount of gas that comes from landfill, that cant be a very scientifically managed mix, but it is commercial, give it a bit more time someone here will find something. Desperate |

You guys appear to have been at it a long time so I guess you know the truth by now. Yup keep going, it IS possible and you seem to be nearly there, imagine how good it will feel when you finally singe your eyebrows off.  I am not sure if running a genny is so economic (unless it is a combined heat and power system) I think cooking and heating is a better use of the gas. ta ta |

Quote "The problem I have is that the gas DOES NOT BURN."
how are you trying to burn the gas. ?
The calorific value of the gas is very changeable, all commercial plants that I have worked on have a L.P.G. / Nat gas pilot burner
with a main base flame of L.P.G. / Natural gas or oil. The base flame being about ten percent of the boiler design.
waste gas is introduced after the base flame has established though additional gas nozzles.
The additional combustion air is added in proportion to the waste gas pressure to maintain a stable air fuel ratio.
Modification of a domestic type boiler or injection into the air stream of an engine with a purpose built mixing system is quite doable
