Gasifier Generator

[vbrent]

Ya can't go wrong here!

How about a small outboard gasifier fed with driftwood, charcoal, coconut husks, fish bones, seaweed, and The Washington Post to fuel a couple K generator or even your 27hp Yanmar? Hah! I could even convert to a wood chip composting toilet, dump it out on shore to dry out in the sun, then dump it into the gasifier to charge the batteries. dump

Fema Gasifier Plans can be adapted to a smaller, conveniently sized model to run a gas, propane, or diesel generator. Cars during WWII were run using trash can sized gasifiers. Here's a good use for all of those empty beer kegs in the aft hold!







Size doesn't really play a serious factor in the computation, as long as there is a steady supply of fuel. Safety concerns are minimal, no worse than a campfire.

The car in front looks like a 70's model something. Maybe this guyhad been using it all those years after the war? Maybe he couldn't find someone to take the picture during the war.

atoll, yep, I was reading that thread when the gasifier occurred to me.

Minggat,
Gasifiers were used extensively during the war to compensate for fuel rationing. For some reason, probably big oil, gasifiers are almost a lost technology. If I retire on the hard, I will definitely have a deep woods off-grid run by a gasifier.

Hello, Gasifiers are making a come back with gas prices getting high every day. Using a gasifier on a boat would be a good idea and coconut shells work well as feedstock too.I know a guy who sells some nice gasifiers too!

Greetings and welcome aboard the CF, Larry Garringer.

What size of boat would you expect to have room to accomodate your gassifier and a woodpile, in addition to an engine?
How big would that woodpile have to be to generate enough gas to power a 15 HP Engine for 24 Hours?

Just be sure to anchor a couple of hundred yards downwind of me. I don't want to get caught up in the conflageration when the thing blows, much less when the boat occupants pass out due to CO leaks.

But first talk to your insurance company. I'll bet they will have some advice.

I'm coming up with about 40 Lbs of wood = about 1 gallon of diesel


1lb of wood produces 35 cubic feet of gas
or 4,900 BTU heat from burning the gas direct
or 1.925HP heat from burning the gas direct
or 0.51 HP of shaft power i.e engine
or 0.459HP of electric power generated
or 0.342kW of electric power generated
1 litre of diesel has a heat energy content of 9.630 kW heat (or 32,895 BTU)

I'm assuming HP and KW are hours as HP/H and KWH

but with a diesel engine you still need some diesel it just extends diesel, gas engines can run on this straight.

so to equal the 30 gallons we carry I'd need 1200Lbs of dry wood mater

Hello its about 20 Lbs of wood = about 1 gallon of diesel you will not get all the BTUs out of diesel the same for gasoline in a engine. I can run a 15 hp engine at full power for 5 hr on 80lbs of wood so about 400lbs of dry biomass for 24hr. keeping a gasifier going for 24hr would be hard. I was thinking more like big boats and using the gasifier to charge batteries and heat hot water for bathing and cooking not to power the boat all day
