Turning an oven into a convection oven

I agree completely with netwarehead. This is a risky experiment. Look at the burners on a natural gas stove. If the flames are blue, no CO. Red, yellow, or orange flames indicate incomplete combustion. Possibly recirculating the water vapor and CO2 into the flame will result in the production of CO.

My suggestion: Build a second "bottom of the oven" - that is, create a 1" space between the existing bottom, and another completely layer of metal, with only a slight increase in the total area of holes in it (for combustion gasses from the oven) to rise through. Then, the fan idea might work; in fact, would probably be fairly simple to do. ABSOLUTELY have working carbon monoxide detectors if you do this. Also, if there's any way you can monitor the flame color, that would help indicate to you if you have an obvious problem.
FWIW, a lot of convection ovens are just regular ovens with a fan in the back.

True. if we are talking about gas convections ovens, then that oven has been tested and designed to maintain a proper internal draft and proper combustion characteristics while running in "convection mode". I'd trust that more than the jury-rigged idea proposed in the OP
 
Just place some bricks or pottery into the oven for a more even temperature. They will absorb and emit infrared.
 
Just flash the firmware. Get ovn_cvtovn224.bin for the latest oven to convection oven upgrade.

Seriously though, imo they are not worth it
Sorry, I love having a convection oven. IMO, it does a much better job than a regular oven for things like roasts & chickens.

We bought one when we moved into our new house last May. While I don't bake/cook if I don't have to, wife loves it. And it does cook better and noticeably faster, too.
 
😵

Improper combustion of any fuel produces carbon monoxide. By altering the air flow, you run the risk of disturbing that very air flow a gas oven depends on for proper operational safety.

Like I said, good luck.

Make it a combination CO and explosive gas detector. If the fan manages to blow out your gas oven's flames, unburned gas could spread and blow up your home. 😱

Like he said, good luck.
 
Hey hey hey! We didn't use convection... we used "air impinging." (which, I think is just a marketing term for convection.)

An Impingement Oven is a specific variety of Convection Oven.

Much like the Square/Rectangle, Rectangle/Square relationship, impingement ovens are convection-based, but are different from regular convection ovens.

Impingement utilizes two fans, both above and below where the food will go, which is on a conveyor belt in the middle. It's the perfect pizza and sub-sandwich preparation method.
After some time on google and wiki, I see it might use fans or jets. I think the typical oven-style use of "impinging" is still the fan method, as opposed to the more general purpose use of the term impinging/impingement, which has meaning outside of the oven/food industry.
 
Just bite the price difference vs selling your regular stove and buying a new convection stove. Not worth the trouble, even if there was no risk, which there definitely is

But you specifically said for "browning" roasts, what, like in a broiler?
 
Probably the fact that I'm a genius.

It would be a vertically-facing fan sitting on the bottom rack using large blades and a slow rotational velocity to conserve energy.

I'm not expert on 18-century engineering, but I'd imagine this could spin for an hour before it needs a re-winding.

Heh genius. Go buy a convection oven.
 

Looks like I win. 🙂 Though all the listings I see say "currently unavailable" which probably means the product was recalled due to house fires, death, mayhem. Or maybe it just wasn't popular. :/
