Changfa Engines / Small ChangFa(iod) in Rice milling plant
« on: October 04, 2009, 07:23:34 PM »
Hi All in my quest for woodgas fueling this video was posted on one of the woodgas sites:
http://www.youtube./com/watch?v=HTcJR7acPok&NR=1
Youtube channel is under the name of¬  Jamestanwh
Shows them cranking up and running the changfa to belt drive the gasifier starting up blower and fill the gasious engine supply piping.
Note the guy slipping off the drive belt on changfa shut down to let the blower freewheel in producer gas stream.
Lots of gasous operating details if you know what to look for.

Yeah. Overlook the lack of belt and fan guards. This isn't Kansas Toto.

Everything else / Nickel Iron (Edison) Batteries Good? Bad?
« on: August 14, 2009, 09:31:52 PM »
Hi All
I was asked by a friend setting up a home battery bank about Nickel Iron storage batteries versus lead acid. I don't know the NiFe type. I have read my eyes out  - looks too much like NiCad characteristics to me. Would require a constant charging due to the high discharge rate.
They are sold by this company; made in China on supposedly  German equipment.

So anyone real world familiar with this battery type? Good? Bad? Pass?
Thanks

Everything else / Flywheel Blowup Pictures
« on: May 17, 2009, 10:42:40 PM »
Hi guys
Here is an interesting insurance company report with pictures of¬  powerplant Flywheel Blowups.
Even though turn of the twentieth century steam plants the same factors as with Listers CS development: the easiest power output increases were with RPM changes. Right up to the point of a blow-a-part that is.
Also interesting is that reading the text the insurance company considered flywheel blowup pay outs to be more expensive than boiler explosions.
Towards the last pages there is a chat of safe 60 MPH rim speed flywheels 30 feet down to 2 feet. A Lister/iod 24" spoked cast flywheel is judged as safe only to 955RPM.

Look under the Historical Literature heading. A long down load but worth it.

Everything else / Firewood Splitters
« on: December 28, 2008, 10:30:08 PM »
Good Morning

We'd been talking on another thread off topic about firewood log-splitting.
Until this year all of my life I've enjoyed hand splitting. Knots and crotches that wouldn't split were ripped with a chainsaw.¬  And yes, due to the amount of energy needed and the sometimes unpredictable nature of wood popping apart I've managed to injure my self more than once. But now due to age I'm just not able to keep at it longer than 2 hours a day. Needed more productivity.

Researching power splitters I came up with three types:

Spiral/Screw¬  ¬  see¬  http://thestickler.com
Has a playable vidio. Was too slow and in my judgement too dangerous. That demo round he was working on was only a nine whack(swing) to chunk up and I would not have had to be¬  bent over to do it. What I needed was something to do knot wood,¬  crotches and 150 pound 1/4 block butt chunks. I just see could see a chunk screwed on and swinging around off center and off balanced while I ran to shut down the motor. All of the wood has to be moved to the splitter. To much wood movement.

Flywheel type. You can find video and plans to make these out of old square bale hay balers. A commercial version at:
http://www.supersplit.com¬  ¬  Has a playable vidio.
The hay baler types are scary. The splitting ram is coming around once per revolution whether you are ready or not.
The commercial version is engable /disengable, and small and light enough to move to the wood. All of the wood blocks have to be lifted up onto the table. And it does seem kinnda expensive.
The gear rack and pinion teeth look to be the weak point and proprietary parts.

Hydraulic type. There are many types and brands. After renting/trying different brands and sizes I bought a 10.5 HP, 34 Ton, 15 Second¬  cycle time with both a vertical and horizonal bed from SpeeCo manufacturing:¬ 
 ¬ www.speeco.com/products/
Anything slower was too slow. Needed this much force to cleave through the 6" limb knots, works great. I can do the heavy blocks on the ground vertically and the fine splitting horizontally  while standing up with a wheel barrel positioned as a catch basin.
Yeah, it is capable of mashing, smashing, amputating fingers and hands.
Did a great job crushing wheels out of the insides of junk tires. I like it.

Engines / Why Not Sterling/Steam?Why Llisteriod IC?
« on: November 01, 2008, 08:19:12 PM »
Hello All,
I get asked this weekly by some friend, neigbor or family member. The most recent was this week when talking to a forum member on the telephone about my "Turning wood into electricity" project.¬  So I'll dump out some of seven months collected research sources that led me here to being a Listeriod owner.
Short answer: more efficient of my fuel and labor time. Here's why.
(Wife wants me to clean up my accumulated stack of info on welders/welding, AC gen heads, Permanet Magnet Generators, engines, mountings gasifiers ect., ect. and the Stirling and steam stuff is on the bottom of the pile at the beginning of this quest.)
I wont bore you too much with whats already been posted on this forum by adhall, Doug, Skeeter, Shipchief, and many other members here under other threads. Look in Advanced Search. I did.

Stirling engines: simple, light and compact, clean and quiet, ulitmate multifuel capable and modern sexy! !

You can Wikipedia history and general development. Here's where I found¬  what's available Today in our power ranges:
http://www.infiniacorp.com¬  ¬  ¬  They currently make and sell a 1kWe Stirling engine with encluded/enclosed AC linear alternator. This is for sale and being used by:
www.gocpc.com¬  ¬  ¬ in a small compact BioMax 1.8kWt portable mobile gasifier plant. CPC shows an actual picture if you dig through their web site. Note the auger style chip/pellet fuel dribble feed into the top of the gasifier assembly.Next:¬ 
http://www.sunpower.com/index.php?pg=25
This will put you on their Power Generations Publications page. You can see a development work from 1969 to 2005. Open up Micro Scale Biomass Power and you will see their 1.1kWe Stirling BioWatt engine being used. You can buy this engine too. It comes also with an enclosed AC linear alternator Free with the engine.
Yeah, 1kw aint much. But both are NASA speced with a 40,000 hour life cycle. Both companies show development of larger 3 and 5kw units but none in useage yet. Sunpower site from the home page and in some of the papers gives good numbers on thermal efficiency: improvement of 16-17% to now 21-23%.
For a bigger more useable  Stirling engine go to:
http://www.stirlingengine.com/ecommerce/category-browse.tcl?category_id=2¬  ¬  ¬ They sell a book showing how you too can make a 5hp/3.7kw engine. Doesn't look to be using any high tech, just lots and lots of fabrication on a one off unproven design.
The current Stirling engine long answer is: too small, too expensive in $$ or labor for no better efficiency.

Steam: good old iron and steel, proven engineering, also ultimate multifuel and slow, slow style romantic! !

For the very best article of todays what, how and why of steam engines read this article by a true steamer named Skip Goebel at:
http://www.backwoodshome.com/articles/goebel43.html¬  ¬  ¬  This is an article I think adhall refered to in the past. It in very well written with the math to back up to back up Mr goebels statments. He says it's cheaper, less labor to buy a diesel genset and fuel. Want to burn wood? Gasify and run in an IC engine. Still want to steam? Through his company Tiny Steam he'll build you a sealed bearing modern engine.
For a real steam treat look here:
http://www.pioneertelephonecoop.com/~carlich/RSE/RSEengines.html¬  ¬  ¬  ¬  the web site of Reliable Steam Engine Co. Current production engine kits from 4 to 200hp. Boilers too.
Wow! Makes me want too build his 5hp turbine kit with his Roberts bulk wood wood boiler.
Problem is: using Skip Goebels math it would eat up 30-40% More wood than gasifing through a Listeriod. My wood may be "free" but it still takes a lot of labor(mine) to get into a useable form.
The current steam engine long answer is: too labor intensive, still can't match IC engine efficiency and still a space (with the boiler, condenser,ect) and water hog.

So thats why I'm here with you all in Lister/iod land. I like it here.

Enjoy
SteveU.

O K links finally fixed now. I think. Sorry. SU

General Discussion / The Names We Call Our Selves and Each Other
« on: October 25, 2008, 01:38:24 PM »
Hi all

On this forum I'm now talking to a lot of good people from parts of the world I've only read about or seen on vidio. This has been great hearing the diferent approches to life and the uses we are putting these slow speed engines to. Some diferences individual, some cultural; even with those of us speaking the same (English) language.

On another forum I've just read a couple of German members trying to explain away a (to them)  funny joke they had shared  to each other on forum about how  a  fellow Chinese members forum name struck them amusing (in phonic German). Most of the Spanish/Potugees members were offended that they too were not invited to the to the "BIG conference in China" too. The Chinese member is so mad he isn't speaking?? I tkink. And the American moderator/forum sponsor it tring to sort it all out. All this beng done in English.

My big fear here is I will say something common to me that will be offensive to someone of you out there.

Here I'll go first.
It is safest to call anyone a citizen of the United States of America an "American".
Please don't call us Yank.  35% are really offended. 25% confused, "Yeah, I'm a Yankee , , so what?" And the rest of us would smile and say "No, I am an American from (name a state or reigon NOT one of five NE maritime states or the old South).

So I know Not  to call a Canadian a Cunuk', a New Zealander a Kiwi, a German a Kraut. Thats rude.
 But what this Oz thing? Is Auzzi bad too?
And I'm really uncertian about calling someone English. To my Scottish and Welsh family wannabes that is an insult. But aren't they part of the U. K. too?  So, UKiuns?  Some of you say you are from Great Britain so obviously British. But how am I suppose to know the diference between an Englishman,or a Britian. I donno'.

Guys, Please help me out here.

Bio-diesel Fuel / Biodiesel Tankless HWH and NonElectric Stoves
« on: September 30, 2008, 09:23:46 PM »
This normally not my area but in searching for the perfect AC generator head I came across this seller:

www.doctordiesel.com/index

He offers Tankless On Demand Biodiesel fueled hot water heaters, modern nonelectric(pretty) Biodiesel heating stoves, Bio making equipment, newsletter, ect.
No generator heads at this time. And I burn wood. So no commercial consideration or affiliation.
He did sound like a reasonable fellow on the phone.

Other Fuels / Wood Gasifer Kit Now Offered
« on: September 25, 2008, 10:36:56 PM »
OK boys and girls, here it is: an affordable motor grade wood gasifer kit for engines 5-20 HP.

www.allpowerlabs.org/gasification/gek/index.html

It appears to be using known, workable design features. It has almost all of the features I was going to incorperate in my first prototype unit this winter.
I really like the fact that the designer is NOT trying to offer this as a turn key system, but as a modular basic starting point LEGO kit. Results will vary with the input that you put into it. Now that sounds like a realistic Lister/iod attitude.

Comments???
