Well that sucks, the company that sold me the bricks was aware of what im going to build, and they ensured me its fine. Thanks for making this clear and providing links for research. It was hot while running. I did try and touch it a few times after i turned it off, but it was so hot i couldnt tell the difference anyway. The port and burner both sit flush with the chamber ceiling. Also, I forgot to mention the burner was running at 0.14MPa (roughly 20 psi) for an unknown amount of time because the pressure rised sometime during use. The pressure I set was 0.1 MPa (14psi). Not sure if it matters, and if my calculations are correct, the chamber is 264 cubic inches in volume. Zak

Hello, First post ever, hopefully not the last. I just built a gas forge, and coming from a coke forge and being used to its simplicity, I probably didn't think everything through as i should, so im here, in need of advice. I used STV-2 fire bricks, not sure whether this is a brand or standard, but apparently its rated for 2800f. Bricks are almost 2 1/2" thick. I couldn't drill the entry hole myself so i asked my neightbour to do it, but unfortunately the hole he drilled was 1/2" too big, so i had to insert a metal pipe in order to fix the burner in place. The pipe is sealed from the top with furnace cement, but i think its rating is not high enough for the application. Inside the pipe and around the burner i packed refractory wool to prevent backfires. The burner is from Devil Forge Today was my first time using it, and after about an hour and a half of work i tried to touch the burner to feel how hot it was getting... i was unpleasantly surprised to find out it was too hot to touch, by the valve, not on the burner body, the valve. My humble opinion is that, the pipe sleeve is conducting internal heat up the burner. Im not scared of criticism, so dont hold back.
