Thread: Forge insulation question

No, once the lining has come up to autoignition temperature it's a nice steady fire. I did not add a flare to the burners since the tip is working inside the forge wall and the flare is built/formed into the refractory. Still, it's more back pressure, swirl/gas-air mix, and forge volume that keeps the flame working.

I also added a front sliding door (fire brick sliding in angle iron channel.

I also tried adding a hard fire brick inside and it worked eventually but took forever to heat up. I liked it when it was hot though.

Sounds good. Yes, the hard brick refractories do take more time to warm up, but they also stay hot longer too. It helps moderate the temperature loss when you throw some cold steel in there to warm up.
