    Bartlett Genesis on L&L E23T-3

    SP is the setpoint of the kiln, I can't remember if we ever found out what the Out values are. I am pretty sure the time is logged in 30 second increments so 0 is the start, 1 is 30 seconds in 2 in 1 minutes in and so on. I think you can only download the most recent firing but I could be wrong. With the thermocouple offset I think that means your thermocouple was not reading the right temperature to start with so you offset it to read the right temperature. No need to be adding or subtracting 58 to the temps when making your own programs.

    Logging of kiln temperature to a computer?

    There's a few of us working on DIY kiln controllers over here. That certainly looks like a pretty easy option for logging temps to a computer.

    Just another electric to gas kiln conversion

    Up to 800-1000c is the easy bit. As low as my burner goes I struggle not hitting 200-300c in 30 mins but the pots I fire have already been bisque in an electric kiln.

    Gas kiln stalled . Why?

    Ok, if it is saying 10psi input I guess that should be for propane. I don't think natural gas ever comes at 10psi. The only reason I was worries is if you are supplying the burners with a low pressure they wont get 60,000BTU as that is related to the size of the burner orifice and the pressure of gas you are supplying. I had no issue using a single control valve before a flat regulator on a 4x burner gas kiln. Actually found it much harder to get an even turn/twist on each burner.

    Corn syrup

    Corn syrup just seem to be a kind of glucose syrup anyway.

    Nice looking setup you have there. I still think with the venturi burner you are going to need a chimney 2x that but it will be interesting to see what temps/cone you get. Did you get the burner from Northern Kilns?

    I am still not convinced that regulator is for propane pressure instead of natural gas. I think you need to find out what pressure that regulator is outputting. Whatever it is saying on the gauge wont matter once you hit the constant pressure the flat regulator is outputting. I may be completely wrong as nobody else seems to be worried and it's not a constant pressure regulator.

    Temperature Algorithm?

    Some of my posts I do spend the time to put both C and F temps but not all the time. It would be a nice thing to have but this is off the shelf software so if the option isn't there already then I don't think we can easily get it happening. I am not sure what you use to view the website but I just open a new Chrome internet tab using ctrl+t then type '2240 f to c' in the address bar and google tells me.

    Pressure gauge reading

    I would do it that way with the one red valve before the flat regulator then you will get an equal flame to both burners. Those valves are not the easiest to slightly adjust evenly. You will have to work out a way to open the solenoid valves and stop the controller closing them or just remove them. I think the controller is working as intended its just not the best way to fire pottery. I remember an old post and somebody else had a kiln that turned burners on and off instead of starting from the lowest setting and slowly turning it up. It would not be impossible to fire that way but brings some more issues. I still think you want to find out what pressure that constant regulator is outputting. I am not sure if it is for natural gas or propane. Some of the issues with only hitting 1400f could be that. Even with the chimney as is I would thing 1800f should be possible.

    Pressure gauge reading

    I have tried looking back through your pictures but I can't exactly work out how it is plumbed together. I think this thing is regulator that only outputs one pressure. I have seen one on my friends natural gas kiln. Are you sure these burners are set up for propane? If this is just before the burners then they will be getting a constant pressure I think.

    Kiln problem

    Are the elements twisted at the end?

    Parian kiln firing question

    I still have some glaze test I should have run 3 years ago I am 90% sure I fired this clay to cone6 with 0 sticking. Had worse from cone10 porcelain.

    How much propane will I use

    3-6 firings a tank seems a good ball park figure. Somewhere there ish

    DIY Refractory on Pyrometer Thermocouple?

    How and when is it stalling exactly? Could be the thermocouple could be the kiln. If it is hitting the right temperature when the cone bends then it doesn't sound too bad or off.

    How much propane will I use

    10,000 btu /ft3 is a good over estimate I find and propane has 21,500 btu/lb so 9 x 10,000 = 90,000 btu x 8 hour firing = 720,000 / 21,500 = 33.4 lb propane. You can probably half this number easily as you are not going full wack for the whole firing.
