Matt, I have seen that one a few years ago. Pelleting green wood? Don’t believe every video you see.

We all wish it was that easy just drop in green wood branches etc. and out comes pellets . If it was that easy i would have a machine tomorrow . but dont you think green wood would plug up the motor valves. as well as all pipes etc. by the way how did it chip up the branches boards and the worse of all the blocks of wood

Henry, Kohler and Kawasaki do make, sell and market currently available water /liquid cooled V-Twin engines in the power range you want.
You can search these up on Internet offered small engines for sale sites.
For a time APL/GEK did use this engine.
Another dandy is the small 3 cylinder inline Kubota water cooled natural gas engines.
Quite a bit more money but with Kubota world-wide service and parts.
Both of these engines choices are coming available now in well used yard/garden/light industrial equipment systems now.
Ha! Ha! Search up water cooled riding lawn mowers.

Based on what I found online and YouTube, this company is out of business for 5 years.

The Kohlers are no longer in production. For now the left over surplus is available for a time, but eventually it will run out.

Yep. Yep.
Your Mecc Alta gen head picture shows SAE pattern flange mounting.
Better to spend even a couple of thousand more in a compatible engine able to do this than having to friz up a pulley/belt /chain/sprockets/shaft-coupler drive system. Ha! I know this one all to well.

Steve I am not replacing anything , Just considering what I should have done . Did anyone pick up on using an escalator braking motor as a DC generator ?

I would think you would want liquid cooled engine for combined heat and power ,

Been there done all that. Just use the cheapest engine you can find that will get the job done. Use exhaust heat for a simple hot water. Go to charcoal, build a system to make charcoal and produce primary heat.
Using a liquid cooled engine for heating is very complicated and you can not use all the heat from engine, you will destroy it. The engine must maintain 165*f to maintain proper tolerance. This leaves very little for heating, you then have pumps, fans, heat loss in transfer. By the time you reclaim this heat that reclaim is lost in energy consumption of the system.

For me there is a heater connection on engine and there is an auxiliary connection on wood gas boiler . Boiler shuts down at 180 f . thermostat on engine opens at 180 f . I guess I also need to stop flow at below 180 f . If it gets there . I should also use heat from exhaust . That requires a bit more then connecting an insulated pipe I already have an excess of .

Torrefied wood pellets were among the products discussed during a Feb. 26 hearing held by the House Subcommittee on Conservation and Forests, titled “Innovative Wood Products: Promoting Rural Economies and Healthy Forests.”
Michael Goergen, vice president of innovation and director of P3Nano at the U.S. Endowment for Forestry and Communities, discussed the potential to use low-value forest material as a feedstock for torrefied wood pellets during his testimony.
During his opening statement, Goergen discussed the purpose and mission of the Endowment. “The Endowment is focused on keeping forests as forests and supporting communities that depend upon them,” he said. “I’m focused on innovation in forest products because markets bring value to forests, and we keep what we value.”
Rep. Doug LaMalfa, R-Calif., discussed the Camp Fire, the 2018 wildfire that impacted areas near Paradise, California, in the north-north central region of the state approximately 90 miles north of Sacramento. He said hundreds of thousands of trees damaged in the fire must be disposed of. “One group is looking at creating a pelletized fuel product in order to further the restoration from Camp Fire,” LaMalfa said, noting that material primarily consists of partially burned and partially charred timber. He asked Goergen about the potential feasibility of the project.
“The good news is we can make these pelletized wood fuels from really low value materials, and I think that’s a terrific option for us in some places,” Goergen said. “The problem is cost—always,” he continued, noting that it is difficult to make wood energy cost effective with fossil fuels. Torrefied wood, he said, offers a solution to that problem. Goergen showed the members of the committee a sample of torrefied wood material, noting it was produced by roasting wood in a low oxygen environment.
Goergen told committee members that the Endowment has already used torrefied biomass to fuel a coal-fired power plant for 12 hours straight. “That plant required no changes whatsoever,” he said, noting the torrefied wood is a very clean, very low-carbon intensity fuel.
Goergen also addressed torrefaction in written testimony. “Torrefaction reducing moisture, increases energy density and develops a product that stores and transports far better than untreated biomass eliminating some of the logistical hurdles that make low value biomass from restoration efforts a little more valuable,” he wrote.
The Endowment is developing a torrefaction demonstration project in John Day, Oregon, that is scheduled to begin operations this spring. In his written testimony, Goergen said the facility is the last stage in the Endowment’s and its collaborators’ efforts to commercialize the technology. In addition to proving the technology, the project is designed to help open a large-scale market for forest restoration residuals and open the door to development of additional carbon products that can be produced from thermos-chemical treatment of biomass.
Additional information on the hearing, including video replay and full copies of written testimony, is available on the House Agriculture Committee website.
It would be nice if someone talking knew or cared something about what they were legislating .
There was a law but that evidently did not mean anyone promised payment would ever receive it .

heater connection not all unused thermocouple sensors shown
have enough of this
auxiliary connection boiler . 8 years still do not have wood gas generator working . then I will need to drain and refill hundred of gallons of non toxic anti freeze .

Glad to hear you are not replacing your 3.0L marine engine.
Your gen head shows to be an 1800 RPM version to make your 60 herz.
Direct coupled at that low of engine RPM and de-rated for wood gas you will barely make your 10-15 Kw/el.
And probably not even that running your four cylinder on only three cylinders.
I missed this somewhere back. Why not restoring full four cylinder power after your tarring recovery?

I can only use 8 Kw . ?

What Steve said, I had GM engineers help me with the Italian machine and they have all the power curves for this engine. The guy I was working with was in RnD working with GM development NG powered engines including this one.
You would be lucky to achieve 10 kW reliably running on all four cylinders. That thing is way over rated.

inverter has maximum output of 8 kw . When I start battery is fully charged , 5 minute timer before it begins to export power at low rate 2 kw . charger starts at 11 amps goes up to 150 amps . I have some failure , power still drained from battery and generator can be reconnected . End of run disconnect inverter from grid . Last time unit ran had failure of grate shaker and total clogging of restriction , should not occur where I need grate shaker to have any flow of fuel through machine .

Hmm. Yes I had hear you say that you only needed 8kW/el due to your Grid feed-in allowances.
But . . . .always oversize, over-rate for the Murphy’s who will always plague you. Or just plain in-use wear and tear power reductions. Real.
Anyhow on pole generators synchronous electrical makers they do not want power inputs evenly around a full 360 degree rotation. Under electrical load yours have four distinct grunt me past this, hurdles. Called cogging I believe. For better input needed power “smoothness” you would need one of the higher poles counts generators. Expensive.
Now on IC four stroke piston engines they only per cylinder actually produce good useable power for ~45-50 degrees of a rotation. Not 180 degrees. Not even 90 degrees. BUT a four stroke cycle is two full rotations for 720 degrees, to repeat cycle.
What this means is your four cylinder engine is only able to push-kick power out for 4 x 50 degrees of that full 720 degrees. So for 520 degrees worth of segments you are momentum of crank, pistons, rods and flywheel/gen head masses coasting along.
Single cylinder engines are notorious for the pole cycles and the engine power cycles matching/mismatching up and creating severe electrical voltage/current “flicker”.
Two cylinder was the partial old way to combat this. 3600 RPM running on singles and twins and this is somewhat covered up.
Four cylinders better.
Six cylinders better yet. Especially with 3 phase multi-pole generator heads.
Eight cylinders the fewest “best” solution. 8 x 50 degrees = 400 degrees power inputs coverage of that 720 degrees to repeat, repeat.
Seriously spend the money time and effort to get your fourth cylinder contributing back.
Regards
Steve Unruh
