[AT] gasifiers

[charliehill]

At one time you could buy a sort of catalytic convertor for wood stoves.  It 
went between the stove and the stack and when heated up burned the gasses. 
Supposedly it really increased the heat output and also drastically cleaned 
up the exhaust gases.  I'd like to have one for my old air tight heater.  We 
got our first cold snap this week.  It's about 51 now and drizzling rain. 
My wood heater is clicking along nicely.  Just hot enough to drive off the 
chill.  The tea kettle on top is not even steaming but I can feel the heat 
from the stove all over the room.  I'm burning a dead dog wood tree I cut up 
a couple of weeks ago.

That sure seems a true statement, Bob.  As I was doing the last post, I was 
thinking about the pretty little blue flames that also shoot from the side 
of a piece of wood as it burns.  Neat to watch.  They seem to just squirt 
out.  At times I wish I had my stove from the shop in the house.  I could 
kill hours just watching.  Maybe I am a little pyro.??  (Grin)
