The best way to burn relatively untreated or lightly treated bio gas is in a gas turbine since they are made with high alloy steels that are very corrosion resistant or boilers, it also helps that boilers and gas turbines burn the gas as soon as it enters the engine.
I work with bio gas and I know people who work at the Cummins R&D plant here in clovis so I have a real good idea what it does.

Remember how some people were saying how wonderful bio gas is?
The boiler where I work that burns 25% bio gas to 75% natural gas is leaking again. Last year I thought the boiler got a full retube for almost $30,000.
Well it turns out they only retubed half the boiler, not through whole thing like I thought.
Well now some of the old tubes that were not leaking have started leaking.
So they bought another 800hp boiler because they learned during the retube job last year they just can't operate on two 1,200hp boilers since the last round of plant expansions.
