Ok I'm a Turbo retard...
Been doing some research on them and talked with a few expurts :o
So I'd like to hear from you guys what you think I should do...
Here's the scenario...
My WOODGAS generator... I want to start it on gasoline, use the turbo to create the suction needed to start the reactor instead of using a handmade suction/blower as most do(just bypass the feul mixer and carb until I'm ready to switch to woodgas)
When I switch over it will be just a tee valve in the air/fuel line to the carb...
You guys think I will need an intercooler, anything special...This motor runs at a constant 1800 rpms...longevity and reliability are a must...I have enouph shit that I can't get done now...so broken generator would be a bad thing
-
Here's a few pix of the Gennie

Where did you find the generator? What does something like that put out for power? I know 101 questions. ;) Just corous if that would power my hobart 250 when welding outdoors on farm equipment?

LMAO
Wyatt.....You kill me
LMAO LMAO
It makes up to 309 volts per leg...
3 phase....
About enouph juice to power a city block or an army mash unit...

Turboes are more compressors than suction really and they need a bit of pressure to get them going to do so.
How much suction do you need to start the reactor?
Since the generators gotta be started on gas what about an electric suction fan?
An intercooler tries to take heat away from the compressed air before it goes thru the motor on a hotrod car. If you are simply using the turbo for suction I am guessing what it sucks out of the reactor then goes to the motor? I doubt an intercooler would be needed BUT the woodgas reactor is something I only know tidbits about from you. If the stuff coming out of it is reallllllllly hot an intercooler might not hurt.
Also at the low speeds you are running you may or may not have enough exhaust to spoll up a turbo unless its tiny.

nice pics, I think the farmers across the road use one similar to that to power all the out buildings, corn dryers, augers and there house then sell the extra power to the local power company!! ;D LMAO that is huge-nice!

;D
I don't fook around ::) ;D
Nutz
When I switch from gas to wood I loose about 25% of available horse power. I'm thinking if I put some boost to it I should be able to keep right around the same power as gas...Soon I should have some progress on the reactor and give a better idea to what is happening...I think I have my coolers and filters figured out so the woodgas should be around ambient temps when it gets to the turbo...I'm just trying to figure in anything that can go wrong before I get it all welded up
-
Oh ya... That's why I'm looking for some smaller maybe junk units....The spoooling up deal...Nut's Some guys are using old shitty vacuum cleaners to get the reactors up to temp...I'd like to be making power...and Iif I ever get this going on my truck.......................................................................................
..............................................................................................
..............................................................................................
The added power of the Turbo would certainly be welcome..... Plus while the truck warms up.....the reactor is too...toss a match and turn the key...shut the valve and turn off the fuel pump and be on my way to mess with Fabr
-
I agree, small turbo. Do you know how many hp the motor is rated at 1800 rpm? How many CI is it? You should be able to get an idea of how many cfm the motor would be using at 1800 rpm to figure the turbo size if you know the CI or horsepower. Fabr probably has some dyno sheets that you could just scale down, becaue hp to cfm should be a fairly straight conversions for gas ic engines. Then you still need a turbo expert to size it for you. :)
I doubt the intake temperature will cause much problem with the turbo, but the tar..... It all depends on the filters I guess.
Have you seen this guys stuff?

Woodgas porn. ;D

Spec how is the work on the garage coming along? Need some help?

I haven't seen this brought up yet, but turbo's only spool under load. Engine get's loaded and produces more/hotter exhaust which spools up the turbo which helps the engine produce more/hotter exhaust and round and round we go. I'm not sure a turbo will work worth a shit in your situation unless you plug in the neighborhood to create a decent load. At idle or cruising speeds boost pressure = zero. I wouldn't be sucking any wood gas through a compressor either. Sounds to me like an accident waiting to happen.

I'll try to answer these in order
Engineer,
I'll have to wait till it gets light out, But I'm pretty sure the motor is a 198 CID Hercules... I haven't done the math on the sizing yet...I just decided to try this last weekend :-\
Woodygas is one of the 1st sites I visited... It's pretty commercialized, but is still a down draft unit I wanted a monorater...so it wouldn't be as fussy on the wood chucks getting tossed in as far as moisture content goes
Wyatt'
If you wanna come up and hang out for a day you are more than welcome ;D
Boost,
So the turbo doesn't build pressure at all when under a constant load?
The woodgas should be cooled and as clean as it's going to get when it gets to the turbo, I too am alittle leary of compressing a ready to burn volatile mix of gasses...But someone needs to get the ball rolling...so I guess I'll try it ;D
As far as building another suction/blower I'd really like not to...they are a pain in the ass to build and the motors aren't cheap, if you want to run it direct drive...
Another aspect of using the turbo would be to power another woodgas apparatus if I wanted to run the Gennie on gasoline...
I think this reactor has the capacity to run the gennie and a smaller motor...but that remains to be seen...It's a matter of piping the gas elsewhere...Kinda like an extension cord
-
Constant load yes, but it's got to be enough of a load to make the engine work. Plugging a grinder or maybe even a garage full of lights I doubt would even make that gennie hiccup. Running your whole house or something might be enough. The low rpms will be workin against ya too, but maybe a small turbo could deal with that. All I know is I could cruise down the road at 4000rpm or so and 75mph and boost was zero. Going up long hills it would climb to maybe 2-3lbs or so, but didn't really go past that unless you put your foot in it. My turbo was considered small for my engine so when I did get on it I had instant power, no lag ;D
-
Thanks Boost 8)
-
Boost does make some good points.Personal opinion is that you need to run that gen at full power 24/7 on boosted woodgas and sell the elly to the power company and then just buy from them what you need. Always a constant load on the gennie that way and the turbo will be boosting all the time as it should be.
-
With that turbo screaming all the time. I wouldn't wanta be your neighbor. ;D
-
Just think of all the "samples" you could get. And free power....... LMAO
-
Fabr has a point about the amount of power I'm capable of making
I'm going to try to get it in the shop sometime today to put a Tach on it
But it's a less than 1/4 throttle to put out 220 on all 3 legs @60Hz with no load... I need an electrical genius...
