biogas

Glen

the JB3 was put back into service - it made all the bugs in the 12 000 000 gal tank happy. so if I am firing at 8 500 000 btuh on nat gas - I would be about half that for the other gas??? It's a difficult burner to do that - as I can set gas separately but not the air - might make for some intersting flue gases! the system was too cold today to crank up the digester - so we have to wait! And JB 3's like it just so on light off! Fortunately I light off on nat gas and then switch to bio on the main gas. Next visit will be more interesting!

looking for calorific content

For biogas produced in a high temp anaerobic process. Need to program my analyser for a "user fuel" designation. Any ideas? Or do I have to have a lab analysis for methane/carbon dioxide/ hydrogen sulphide content?? Utility is resurrecting a Volcano boiler to preheat the composting/digesting material. Burner unknown at this point - will find out tuesday morning. kcal/kg would be the most useful measurement.

Nooooooo...

there is no " Content"
that is repeatable

figger 500 butes/ cu ft

marc friedman

bye the bye ..

we call it ." **** Gas "

Glen

that is -

only one of the names I heard it called at the pant the other day. So on avg - then is it 50% methane?

marc friedman

glenn ...

the btu content can vary a LOT...
but not more than, say 500 butes/cf
it is mostly ...
nitrogen
water
sulphur
grit
with something flammable mixed in

I do a LOT of **** Gas work

marc friedman

Ooooohh ..

just read the "anal-yzer" part

fergit that ..!!!

Glen

so then -

no testing for flue gases. that's posivitvely anal. :-)

marc friedman

you can measure yer O2

that is a good figger

all the other calculations will be wrong
