[Stoves] Gas handling

[Crispin Pembert-Pigott]

Dear Jock

 

>Another problem disks with central apertures used as concentrator rings is that they direct the how pyrolytic gases AWAY from the secondary air coming in from the edges.

 

Well, that is just because the design is bad. Generally speaking, for ND-TLUD’s the secondary air should be introduced just above the top line of the fuel. This is in order to keep the stove as short as possible (because tall stoves are unsafe) and to give the flames a change to burn out before getting to the pot.

 

The three washer mixers look really good, BTW.

Crispin
