[Stoves] Canisterium and Tincanium

[Thomas Reed]

Dear All:

I should have also called attention to the wonderful world of 
canisters.  They are much better than tin cans for building stoves with 
an outer chamber of air delivery. 

They are available at most thrift store for < $1.  I have a collection 
of several dozen in all sizes in my basement workshop. 

Too bad the word "canisterium" doesn't sound "elemental".

Dear Lanny and All:

Congratulations on making a "Tincanium" chimney from coffee cans.  Very 
clever connection.  Coffee cans are ubiquitous.  I can get a few dozen 
from my church every month and it makes them so happy to have them used. 
------------------------------------------------------------------------

I have noticed that in the last few years SOME tin cans have an 
innwardly projecting lid.  That seems to be what you are using and is 
probably necessary.
------------------------------------------------------------------------

When I was a kid there were lots of publications telling kids how to 
make things out of tin cans ("TINCANIUM").  I don't think any of my 
children or grandchildren have learned this art. 

It is surprising how much heat tin cans can stand for years and years.  
This is partly due to the Agua Das approximation:  The wall temperatuare 
surrounding a hot gas will be halfway between the gas temperature and 
the air temperature.

This is compounded by the Tom Reed:  Radiation increases at T^4, so the 
wall will be even cooler.  In recent measurements of our operating 
gasifier with a radiation pyrometer the highest temperature measured on 
a drum with gas at 700 C was 250 C. 

(What! You don't have a radiation pyrometer!  They cost ~ $100 and are 
amazingly accurate and simple to use.)

Onward...
