Crispin,
Roughly 5.5 kg/hr of premium wood pellets, with no clinker. The goal is
to rescale the device for wood chips to be fed by the live wall bin.
Small but not to small. I want to come up with a practical minimum
diameter for the chips we have. After that we'll see about burn rates.

Dear Fun in sunny Kingston
I am happy to see you getting that sort of power form a 2" pipe. I am trying
for 3.5 kW from the same pipe and it works well.
I would like to see it running at the end of the month - if you don't burn it
out before then!
What is your burn rate - kg/hr? Do you get evidence of clinkering (ash
melting)?
Regards

Subject: [Stoves] Platform forc burner development
Sent: Aug 5, 2012 12:11
Dear Shoe-String Designers,
In order to move my gravity feed burner development outside during the
warm months, I have built a barrel based platform to mount the burner
and a variable speed blower to dial up the draft. This allow the
platform to mimic common chimney conditions or indeed higher pressure
differences. During trials today the Pellet Pasifier (largely based on
the Dasifier https://sites.google.com/site/dicksfoundry/Home/dasifier
)was able fire at up to about 30 kilowatts, all through a ~5 cm throat.
The burner mounts on the green barrel and the blower mounts on a water
cooled plate on the red barrel.

Here is a short video through a port in the side of the red barrel.
