[Stoves] air for gazification

[Boll, Martin Dr.]

Dears, 

First of all:

 Andrew, is great to hear the (before my eyes optical animated!) expression
"distance cubed"!

Let me add the expression "cross-section cubed". ( intend to see that too!).

Frank, I like that you brought the discussion to that point. 

So the thread-theme, which I began, seems to be a boomerang.

Why?

I intended to get to know some amount of air related to the cross-section of
the burning-chamber (or grate) which makes a good gasification in a T-LUD.

 

I thought -without talking about it- there must be a certain minimum and a
certain maximum amount of air per minute/second which makes a good
gasification for a certain stove. And I expected to hear somewhat of that. I
thought there must be a direct proportionality between the size of the stove
(grate, cross-section of the burning chamber) and the amount of necessary
air for gasification.

 

We can express it as you wrote in:

- volume-unit per second (cm^3) or 

-grams per second (g/sec) or 

-speed (cm/sec) of air per square-unit (cm^2)

 

I hope one of the Pauls' or Tom R. will tell us about at least one of that
different amounts of measure units, which make a good gasification.

 

- Before closing I want to throw another idea into discussion, related to
that:

How about making a T-LUD burning chamber with different cross sections on
top for begin (=strong upwarming /boiling) with bigger cross section and 

in the lower part of the burning chamber a small cross-section then for the
following lower heat output  (=simmering-time).

The optimal air-flow per cross section could be managed by that, which is
the possibility of a better "quasi" turning down-ratio.
