[Stoves] Stratifying TLUDs for 'turn down'

[neiltm at uwclub.net]

Very impressive, and on a totally different scale from mine!  I 
particularly liked the neat and robust looking 'throttle butterfly' 
utilising what looks like the screw on cover to an LPG cylinder?

That's also one heck of a backyard charcoal production!

Is such a large stove necessarily always a high heat output, or can you 
tame it sufficiently for lower simmering heats?

Two days of endless rain stopping play here.

Best wishes,   Neil Taylor
