[Stoves] Screw feed TLUD

[Peter Verhaart]

Dear Crispin,

The burner is for space heating and therefore in the 10 -20 kW range. I 
think a screw feed mechanism needs wood particles of great uniformity. 
Chopped bits would probably jam and exceed the cranking ability of one 
person.
I believe all industrial wood burning equipment has a bottom feed - top 
burn system.

Best regards,

Piet
