I think I have come up with a small(8-10 cu ft) flat top down draft gas kiln design but need help with burner placement.
I will use 2 venturi burners(hi pressure regulated) coming in from the back each left & right beside the exit flue.
Between the interior wall and the ware shelves, how much space should I allow. The shelf layout will be either 4 14x14 shelves with 4 inches between the interior wall and the side edge of the shelves on both sides or using 13x13 shelves this will allow 5 inch flame channel on each side with something of a half brick about 2/3rds down the channel to lift the flame.(no bag wall)
The bottom shelves will have either a series of 2.5 in bricks under the flame side of the shelves to keep the flame from being sucked out the exit flue until comes down in the front face of the shelves. there is also a 2 in spacing between the back set and the front set and 2 in between the front set and the front wall.
This is going to be a top loader with a hinged 3 in fiber top firing to cone 6 and maybe cone 10 reduction
I'm wondering if I have missed that something someone here might see.
