My friend has this gas kiln that we fired a few days ago, the pots actually came out really nice but the design of the thing is confusing me.
It has six burners, three on the front and back side. The flue goes out the bottom at the back but it also has a damper on the top not in the chimney
I have never seen anything like this before. I am not even sure anything was going out the flue at the bottom. The damper is a flap like thing that you open and close.
No idea how we fired it with good results. Started with the flap slightly open and went up to 1000 degc Only closed it slightly to start reduction. If I completely shut it then the temperatures started dropping.
It seems strange and I am not sure what the gasses are doing when they go in, I feel they are all exiting through the top of the kiln.
