Yes all ovens need to vent
The powder gives off a gas that needs to be removed
Not venting can lead to issues with the coating
Lots have a poor door seal which is enough of a vent
Gas ovens need a bgger vent but hey all need to vent
Yes all ovens need to vent
Thanks for that! I will check out the plans I was going to use for my oven build and see if the vent is included.
I think you hit the nail on the head with your closing line; I just don't have time to add that to my plate.Joe Jones wrote: ↑Thu Feb 24, 2022 5:17 pmThat is interesting!
Again, you probably have it "figured out" but even you have to RIG something that works.

Honestly Robert, if YOU put a package together that works well, and doesn't end up looking like it was built by the Three Stooges with Lucy and Ethel supervising the project, I'd certainly be interested, depending on the total price, of course. You could either sell the PLANS with a detailed and sourced shopping list of parts, and some comprehensive HOW-TO assembly instructions (or a video?) OR you could sell the parts and ship them out at a modest profit, but that seems less logical, considering how easy it is to get most anything delivered to your door these days.
So much going on. so little time...

You may find the door seal vents enough on an electric oven but a 1in tube would be more then enoughJoe Jones wrote: ↑Fri Feb 25, 2022 9:21 am So ... as I understand it, the electric oven needs a vent simply because the air inside expands and the pressure needs to go somewhere. I think a simple 1" pipe or so would suffice. Or does it need to be a "stove pipe" ?? If it is just for the gasses that come off of the powder, I can't imagine that I need a 'YUGE escape route for the gasses and HEAT.

I did ask the local forklift salesman if it was possible to as side shifting to the blades. He said, "Yes, for about 1/4 of what you paid for the forklift"

For most of those building ovens here I’d agree 100%. My larger oven is right at 1100 cubic feet so I need 2 burners to satisfy the load and have a relatively short preheat time. No point in not staging them appropriately for me as once that thermal mass gets closer to temp and the speed of heat movement into them slows, there is no point in short-cycling ~450,000 Btu/H. I am very familiar with PID controllers and while you’re correct about the basic terminology don’t be too quick to dismiss the ‘thermostats’ used in home HVAC/R today. They operate with similar algorithms to control electronic expansion valves and variable capacity compressors, variable stage gas furnaces, and/or multi-stage equipment and often times do so with adaptive ‘smart’ recovery. These aren’t applicable to oven technology but they were the comparison made to which I was referring.34by151 wrote: ↑Fri Feb 25, 2022 5:21 pmFor those reasearching a build or building an oven,rdj357 wrote: ↑Fri Feb 25, 2022 1:25 pm As for heating in stages - the reason I want to do this is the same reason you have an accelerator on your car and not an on/off switch.

The thermostat is called a PID Controller (look up the differences)
2 stage heating can be done with abasic PID controller like a rex c-100
3 Stage or more needs PID with ramp/soak features or a multistage option. These are a lot more expensive than a basic pid and the programming is not somthing id recomend for your first pid controller.

Its not how hot it can get but how quick you can get there the is important
Assuming I do not have the time to research God only knows how many books on the topic, can you be a bit more specific about where I might find the information?
That is good advise. There is a great explanation as to how these work (linked to below).34by151 wrote: ↑Mon Feb 28, 2022 5:50 pmIts not how hot it can get but how quick you can get there the is important
The faster the rise time the better.
For the rest of your quiestion do some reading on PID controllers. I can then answer any questions you may have.
Im guessing that will be a light bulb moment for you.
If your cooking a turkey it does not matter how quick the oven (time to rise) gets to temp and it not important how stable that temp is
