yes, it works, and well.
i have been with lowell and his sawdust injection
kiln, and it is without a question...fantastic.
of course that means lowell is too...and we know that.
he is one of the brightest fellows i have ever met.
we have tried injection at the farm. used an old lectrolux
vacuum cleaner and it worked great.
we just did not want to keep it up (too small). we have not
built the right injection system yet. but, we will one day soon.
dry saw dust just explodes when it hits the red heat inside
a kiln.
many industrial furnaces are using saw dust. and, lumber folks
have found it to work wonders in drying wood. why throw
away your fuel? in fact, the saw mills in our area have a
good business selling sawdust. many coolers are packed
with sawdust. hollow plastic shells, filled with sawdust.
it is good to note that scrap wood is not as easy to get as
it used to be. lots of business folks have found that firing
wood industrially is a sound idea. free fuel, and with
prices going through the roof, use it.

I have a sawdust injection system built by Lowell Baker, and it works
great...got to cone 7 no trouble, first firing in a casted 55 gal. drum
kiln......I like it a lot, but you need open air and lots of room...ie, no
close neighbors next door......it's like a firework show firing at
night...so much fun.......Melinda Collins, Antigua, Guatemala

As mentioned, sawdust needs a blower or some type of injection
system. I've experimented in my wood kiln. If you drop sawdust
in from the top ports of the door, it just drops onto the floor and
burns there. If you pop the sawdust into the air by flicking the board
of sawdust, it works a little better. You get nothing like an explosion
just by placing sawdust in a cone 12 kiln. You need oxygen.
I have better luck making a sandwich of sawdust between
two flat boards, and hitting the back wall when I pitch the wood into
the firebox. When I do this, you see sparks flying out of the top
blowhole. Doing this, you also use the velocity/movement of the air
entering the firechamber that floats the sawdust particles.
