[Stoves] Fuel Management - Bamboo Sawdust

[Crispin Pemberton-Pigott]

Dear Andrew

Is there any chance of obtaining a picture of such a device. It sounds like a very simple ‎mechanism that can ladle out a reasonably consistent supply of sawdust.

I should have mentioned the possibility of Tony V building a large Mayon Turbo Stove which will burn sawdust as easily as rice hull.

I made with two REAP interns of Roger Samson's an version of that stove with much less excess air and a higher char to gas conversion rate. Contact Roger for that design.

Regards
Crispin

Crispin and Tony

A long time ago I saw a sawdust burner that was largely self tending
using this method.

It was a high mass cyclonic burner and the combustion air entrained the sawdust.

The sawdust was held in a 205 litre barrel with both ends removed and
this sat above a slowly rotation disc. Thus a small layer of sawdust
formed on the disc and this was sucked through a simple paddle
centrifugal fan and delivered into the combustor.

I do worry that Tony's post says the bamboo sawdust is treated??
