Good Morning Max g.
Thank you for the walk through responce.
I re-read your edit copy. Good. You are filter system sane and useable.
Max your intro post said you were weary of “agenda, agenda, agenda”.
I certainly wearied of idealist, futuristic “someday” designing/building based on a Hollywood’s screen writers fantasy scrip. It was like chasing for the elusive fountain of youth, or lead to gold dreams. Only with real blood, sweat, tears and today money.
I have found here on the DOW that the actual site name words are the agenda.
DRIVE (IC spark piston ignition engine shaft power for a use) ON (doing/using) (real) WOOD.
So, less talk/speculations. DO MORE with actual today available IC piston engines and wood fuel.
I think you will like this agenda here.
As a premium member you can bring up my members page from my name anywhere in blue and view into my now 9 pages of photo’s. A lot of ME in those photo’s. How, Where I live. WHY and for WHO that I woodgas make and use. Ha! Even one back side photo of the actual me. (in PNW loggers clothes)
Your, “the circumstances dictate the options almost mandatorily . . .” speaks to the base core gasifier truth.
My work and desire for home based self-generated electrical power fueled by site grown wood dictates all of my system decisions choices.
Max my small generator engines need all of the parasitic power draws removed as much as possible. I was encouraged a few years ago to stop thinking cyclones and switch to very large heavy slowed gases velocity long paths settlement chambers. Less pressure drop loading on the little engines to have to suck. Mine in my picture album was a 1st?, 2nd? generation concept. Ash and soot settled out of the producer gas. Ash and soots settling into a slide out SS catch pan was introduced on the 3rd generation.
Rapid cooling still kept above dew point seems to help much with this dropping out. WayneK evolved to doing this independently too. My “bin” cooling dropping out system uses gas heat to wood fuel bit condition by drying just-in-time, pre-hopper. What I cannot show is the actual active elements inside the “bin” assembly to increase soot dropping and for temperature control. Not my design. Now patented by the developer. The basic consepts of three benefits in one constuction are still sound and can be applied out, however.
THIS “bin” system to be effective weighs as much as your whole proposed Micra system will weigh.
Has nearly the same space footprint.
This combo unit would HATE to be vehicle or roads shaken. Stirs back up the settles ash and soots. HOT, dry filtering.
Stationary I have the space to try much that would be vehicle impossible.
Example: my gasifer building is still an open ended 5.8 meters by 12.5 meters. If I want I could put in a 6 meter length of 200mm cast iron sewer pipe horizontal at a say 3 degree slope. Introduce the hot, wet, dirty producer gas at the one end. Allow to flow though, cooling, condensing, washing. Concurrent flow; or, reversed counter-concurrent flow. Add different slide-in impingement elements. Fill with wash stones, ect. A WET system for sure!
This building has NO heat other than the gasifier/engine/gnerator system. I need heat. Or install a wood stove and then have another wood slave to feed.
Some kind of evolved wall “pipe” configuration would be able to prove useable for my engine-generator if I had not been given this “bin” system to use. Nothing new here. Usually pipe systems usually seen as vertical tubed coolers/condensers/washers. I’ve seen racked held pipe serpentine versions now in metals or plastics. MikeL’s GMC for one.
The “new” is here: raw wood fuel bits “V” trough held against this big pipe, raked down from the one end to the other as they dry and condition. Remember I am stationary, roof covered.
This brute, heavy, spread-out “simplistic” Combo purpose would be impossible on a vehicle or a portable system.
Ha! Ha! The problem some of us have now is whatever we are seen doing will be seen to be as the universal “ideal” ANSWER.
Welcome to the club brother Max. I declare you my Senior.
So I get to kick back and just sleep now, yes?
I am learning now to say, “go ahead and YOU try that” to the people with much suggesting but little to no doing. Maybe they will have better suscess. On 100% known fails to just say (colloquially), “Good luck with that”.
No majic do-all, for-all, answers to this. A RANGE of possibilities. A RANGE of decision choices we each must make.
On your systems descriptions:
by gable - you mean the basin end wall out of the top cover
basin is an actual SS sink basin now “roof” top covered
this is located within the Audi’s trunk area (boot)
you are useing a single condesate collection vessel internally divided for the different pressure areas (wise - some tried to short cut WayneK’s version of this and learned why not)
you are using the modern Swede/Finn way of pressure hearth blowing for starting up
Flamenco is a searchable trade/brand name for a paper filter system
“volang” means? step? shelf? pleat? ring?.
I will leave you to explain gas reheating.
Not done here yet by anyone that I know of including myself.
Only mentioned by Dutch John. Then none asked.
(hint group: lets him be able to use that Flameco paper? filter without, hopefully, wetting destroying it?)
