The pressure is on!

Middle Tennessee Gas Company came out in the rain and put pressure gauges into the system at several places. One before the regulator, one after the regulator before the meter, one right after the meter and another where the line change to 1/2 inch piping. Now with the two gages I have at the burners, that makes 6 gages in total. What fun for an engineer!

Took just a minute of running the system to determine that the orifice in the regulator was too small. It took just another minute for them to replace it. The pressure at the burners is where it was designed for.

Now, it is time to make some ware and see if it will reach temperature. [It also has to get warm enough so all my clay isn't frozen solid]

I've got gas!

Middle Tennessee Natural Gas came, set the meter and hooked the piping. I decided to have them do the plumbing. They have the tools, the materials, etc. and it seemed to make them more comfortable. As the kiln operates at a pressure way above normal house pressure, they raised an eye brow or two when I started talking to them about the kiln. They did a good job and I have to admit I would have taken far, far longer to do it. I have even lit the burners - sweet.





Here are a few shots of the arch construction. I changed the design a bit. I had enough "extra" IFB to add a layer. So the make up is, hard brick arch, two layers of kaowool, a layer of IFB, another layer of kaowool, chicken wire and finally a covering of Insulating castable. Hopefully that will keep the heat in.











I cut the hole through the roof yesterday and flashed it. Today, it is time to stack chimney brick.
