[Terrapreta] Eureka!!! It Flared

[adkarve]

Dear Sean,
the T-LUD stove consists of a pot that contains wood chips and a space above the pot where the pyrolysis gas is burned. The wood chip holder has relatively small holes near its base for primary air. This pot is filled with wood chips. The chips are ignited at the top and the burning front migrates downwards. Since the primary air traverses from the base of the fuel heap to its top and the burning front migrates from top of the heap to the bottom, this stove is called Top-lit Up-draft, or T-LUD. Above the chip holder pot, there is a space, where the pyrolysis gas emanating from the burning wood chips is  provided with secondary air, so that it get completely combusted. To make the utility of the primary and secondary air clear to the uninitiated, I use the analogy of a kerosene lantern and a kerosene wick stove. In the lantern, the flame is surrounded by glass, so that it gets only primary air. Therefore the flame is sooty and yellow. In the wick stove, the flames are surrounded by a perforated cylinder, which supplies the flames with secondary air. As a result, the flame is blue and without soot or smoke. 
Yours
A.D.Karve

  Hi Kurt,

  Did you see the question mark (?) at the end of the first thing I ASKED you, about your TLUD design? < There is another one.  It was a QUESTION, not a STATEMENT.  If I knew the answer, I would not have asked you.  Is it wrong to ask question, in you opinion, rather than claim understanding and MAKE a fallacious STATEMENT, showing you don't?  Ooops, more questions there.  Is this going to confuse you?

  Continue to "flare off", good man.  You are doing the right thing for the environment with your TLUD gasifier.

  As usual, Best Regards,

    Well now, if you understood anything about TLUD gasifiers you'd realise 
    how wrong you are in that.

    If I want clean tar free gas to run an engine I would doubtlessly use 
    such a gasifier.

     BUT in this situation I want charcoal from the simplest possible 
    device, without stinking up the general surroundings with smoke and 
    without sending CH4 into the atmosphere. I'm not presently interested in 
    the gas it produces, as an energy source. If I was it would be built 
    differently and more elaborately. So at present I just want to flare off 
    the gas.

    And I'm not interested in selling it to people, I place it into the 
    public domain, with a Gnu GPL type licence, if you like. Anybody can 
    build what I've done and on a number of scales, from a 20liter oil drum 
    to a 200 liter oil drum, to something much bigger. The stove developers 
    are building them from tincannium for use in 3rd world countries. And I 
    got my ideas from them.

    Anyone who uses this simple concept can make enough charcoal to improve 
    his garden, without having to pay inflated commercial prices and without 
    annoying his neighbours to any great extent.

    who isn't a BSc(IT) and hence more interested in simplicity than in 
    secretive bloatware.
