 New blast door. I made a new blast door for the oven today, all cut with a plasma cutter.

| Re: New blast door. Nice man, looks badass Can someone explain to me how the more i block off the door of my pizza oven, the harder my fire roars, I understand it creates some sort of vacuum, but it blows my mind, i could watch it for hours haha. |

| Re: New blast door. My oven roars like a train with the blast door on it, same, I could watch it for ages. I even had it huffing like a train some time ago too with the blast door on.

| Re: New blast door. I personally feel the blast door works by decreasing the turbulence in the oven opening thus increasing airflow. |

| Re: New blast door. Isnt it just a restriction like a venturi? Reduces flow but increase velocity or something like that? Who cares, it works a treat.

| Re: New blast door. Question: I have a double skin stainless flue which is insulated. i thought it would be cold on the outside but with my latest fires (still curing) but getting really big fires.. its getting almost untouchable. I have been having a blast door on the entire time.. with really maybe 2 inches air at the bottom... Soo.. would this cause the air going up the flue to be hotter because it has less cool air flowing up the chimney? If so, ill just avoid the blast door once the fire gets roaring. Or am i going to have to live with a hot chimney? just worried about rendering up against it.. and it passing through a rubber boot. |

| Re: New blast door. Does the double skin have vents cut in top and bottom, the ones Ive seen installed in houses usually do? This must create an airflow that helps keep the outer skin cool, without it I would imagine the heat just transferring from the inner skin to the outer via the air gap? Those silicon boots are good to about 500c from memory.

| Re: New blast door. Nah it's got ceramic fibre insulation between it. 1inch of it. Barely an air gap. Silicone boot is a black dektite so unsure of Temp. Is my theory possibly right? |
