This forum doesn't have space for attachments left, so it's best to store it somewhere else and link to it. That might be your own web space or something like Photobucket or Dropbox.

Description:
This is partly an experimental stove, to test ideas. It is designed to be taken apart easily, to modify the design as experiments progress.
The batch box is constructed from steel, lined with 25mm fire brick or Vermiculite board. The batch box port is on the left hand side at the back, with a short tunnel leading to the port and riser, so that the 'riser' sits inside the brick bell.
(The 'riser' is very short, relying mostly on chimney draft - the experiments I've done show that when combustion is complete, all the burning gets done in a very small volume.)
There is a Walker-style secondary air pipe in the short tunnel. This is a simple - made from 50mm square ERW steel tube.
The port itself has a sloping top surface - to try to direct the jet of flames downwards into the 'riser'.
The brick bell is constructed so that it has a large radiation surface facing out into the room. In the top of the bell is a stove-glass window, so I can see the combustion in the riser.
There is a vermiculite board 'gate valve' (inside the top of the batch box) that can redirect the exhaust from the riser back into the top of the steel batch box, or can divide the exhaust between the steel bell and the brick bell.
The exhaust from the brick bell exits from the bottom of the bell, under the 'riser' and into the bottom of the batch box shell, where it goes up to the flue exit. This path might be insulated so as not to lose more heat.
The chimney/flue connection is an existing small old fireplace built into the wall. The chimney will be lined with a 150mm stainless steel liner, with vermiculite insulation. It is ~10m high.
I've not shown the steel bell - I forgot to include it in the drawing I uploaded. This would sit on top of the main batch box, instead of the flat top shown.
