Hi All
Firstly appologies for the delay in getting the photos posted.... but here they are...

A couple of things to note...
- please ignore the black drum in the photos. I use this to create an oven when cooking joints of meat. Usually, I cook directly on the grills over the coals
- the wooden structure is the prototpe chimney to see how effective it is
- as mentioned above, the open face is around 1800mm x 900mm
I used the prototype chimney this weekend with mixed results...
- When I lit the coals using one of those chimney starters, there was no d raw at all and the smoke came out of the front
- After a minute or so (I guess once the air warmed) the smoke started com ing out of the top as expected.
- There was no noticable breeze but the smoke path varied from
- coming out of the chimney then going up as expected
- coming out of the chimney but then coming straight down onto the cook (i. e. me!)
- Although in general, the smoke came out of the front of the chimney as e xpected, there was no noticable draw that you could see from the coals (e.g )
In order to try and reduce the amount of smoke for the neighbours, I had an idea of spraying a light mist of water (I had read that this would capture the smoke particles and reduce the smoke). It did appear to do this but a s soon as I started spraying across the chimney opening, the draw completel y stopped... So much for that idea :)
Only other relevant thing I can think of is that the trough holding the coa ls is cast out of concrete with bricks on the base. There are no vent hole s in it. The cooking grids then sit on top of this....
Any advice would be very much appreciated
thanks in advance
Lee.
