Hi, why do people use bags to store biogas instead of tanks most of the time. All these modifications are to be able to adjust to low pressures of bags right? So why bags? Is it too dangerous to try to compress it or store it at higher pressures?
I wish there was a decent video on using a compressor to pressurize biogas into a propane cylinder. I've seen some but nobody explains anything. But it's doable.
@@tropicallivingoverseas5202 ...here is an old film, but he does make his own methane, compresses it and uses it in his car ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-h4tAQeAz73w.html
I think it's because of the hydrogen sulfide or what ever gas that corrodes metal. The small scrubbers people make are probably not effective enough. But I have seen videos of people compressing biogas. But since these people want to be off grid and want things to be easy a compressor is an extra step and a lot of electricity when you can just drill a bigger hole.
this doesn't really show anything just a guy working on stuff and other guys interrupting him with kind of inane stuff. can we get a video showing close up what exactly he is doing and changing without the live audience?
I felt the same way, being a novice. Please do a close up step by step how to convert water heater, stove and refrigerator. Please. I will subscribe and wait. Thank you for this video.
I’m a bit confused on the modifications needed. When biogas is filtered it should come out at about 90-95% methane. Standard processed LNG should be appx 95% methane. Why is there a need to modify natural gas appliances? I get propane conversions but I’m still confused as to not just selecting a LNG water heater vs modifications to a LPG heater.
I think it’s because the biogas is unfiltered so it contains 40% co2. If you filter out the co2 and hs2 then it’s classed as bio methane rather than biogas
your explanation for the thermocouple is wrong. a thermocouple opens the valve electrically,heat makes millivolts. just saying,other than that a great vid
please don't tell me you guys pay for this info. This is something you can sort out easily by yourself!! dammit we have been doing this since the 70's as a matter of fact.
This may seem like a crazy question, but why does every one use a pump for the gas instead of just putting some type of counter weight on top of their gas bags? Seems to me that most are consuming one type of energy in order to use another type of energy
If you have an excess of wood gas that would be ideal, wood gas just needs heat not fire. So ideally you could compress a propane tank with wood gas and use it to make wood gas for rest of your needs. But paying for one energy source to make another is just ridiculous,
Hi Ernest, My understanding is that the appliances like the stove or waterheater need a consistent amount of gas. Weight stacks or draw alone do not provide this, so they use the small, low-powered electric pumps.
@@ThePermaculturePodcast Hi the problem isn't the pressure coming from the gas bag not being constant but most people use thin pipework to the appliance causing a pressure drop across the pipework when the main burner starts up. If the pipe diameter is increased this would make a lot of difference. Lower the pressure used the more difference. On natural gas in UK pressure is 21mb (millibar) so to supply a combi boiler 22mm pipe would be used. While LPG is 37mb and most of the time could use 15mm pipework. This all depends on the length of the pipe and amount of bends and or elbows. Basically keep pipe as short as possible and use appropriately sized pipe, bigger is better. If the bio digester is connected to the bag as the pressure increases it slows down the production of the gas. So in that case more than one bag is needed. I hope this helps
2 to 4 times larger in order to maintain flow rate. He started with 1/8 and went to 9/64. He is just a handy man type and has no clue. He just messes with stuff until he gets it to work. What you want are the slides that were presented and that he is working from. Lol. But it seems 1000 BTU natural gas, 1200 BTU lp, and 600 BTU biogas. I think you would need to figure out the BTU in lp vs biogas and adjust flow accordingly.
He should have held up what he drilled out to show UP CLOSE what he did. And does this man do any work for people who offer to pay him to convert these? I need some stuff for a construction trailer being converted..
