[Stoves] Comments about T-LUDs

[Crispin Pemberton-Pigott]

Dear Andrew

There is a version of a coal stove which was early days before the downdraft 
I made for JHB shacks.  It was a single pot stove that sat fully into the 
top where you mention the hob would be.  It clamped on top of a Vesto body.

Sink the pot.  It is only necessary to make the hole the right size and 
place the chimney draft on one side to get a huge increase in heat transfer 
plus lower losses from the pot.

The lid of the pot sits flush with the deck.  Lots of stove do this and so I 
made a box with the pot sunk (at pot 2 position) with a removable (loose 
insert) downdraft (cross draft??) burner sitting at Pot 1 position.  It 
works really well with chacoal, coal or wood.  I think it costs $50.

The first pot is placed in a grate over the 'back' of the downdraft fire and 
boils very well I must say.

The whole box of a stove stands on 4 round tube legs.
