Correct. Not only is it methane, it is very lean methane. Around 40%co2. So if it is allowed to mix with air in the manifold, the way a burner is designed, the fuel concentration will be below the flammable range.
@BiogasUSA do heat your biogas digester ... I live in a cold climate with a winter...do have any video showing how to increase gas production, for Colder climates?
Hey, sorry for the late reply. I don’t have a video talking about heating my digester, but this is what I use: www.amazon.com/dp/B0CGJ2R98K/ref=cm_sw_r_as_gl_api_gl_i_MQQA8N5KH7S8GB1FYGR5?linkCode=ml2&tag=nateslink-20 I don’t think it’s a very efficient way to produce energy, but it allows me to continue tinkering through the winters.
@772777777777777 see about an insulated box/crate in your back yard and a small heat pump plus vent under and over tht runs on solar? A simpler solution could be surrounding your biodigester in a greenhouse of sorts maybe add some painted black barrels that help absorb heat during the day and then release it at nigh
thanks for the good info. I'm interested to see the project continue, hopefully you're still making videos!?
Same! Ty for building a whole channel on this topic!
Paintball c02 tanks for up to 4000 psi in my minimal research maybe your ticket to cryo compression
What was the drill size?
I presume the biogas is all methane and has less calorific value than propane, hence you need to up the flow rate?
Correct. Not only is it methane, it is very lean methane. Around 40%co2. So if it is allowed to mix with air in the manifold, the way a burner is designed, the fuel concentration will be below the flammable range.
Do you need to drill out the burner holes to a larger size aswell.
I did not. Just the one hole you saw seemed to work for me.
