Building second oven - Forno Bravo Forum: The Wood-Fired Oven Community



New Forno Bravo Forum Feature

Forno Bravo Forum Community,

You will notice a new forum at the top of the main page called, "Ask Me Anything". This forum will be used for live one hour "Ask Me Anything" (AMA) sessions hosted by people who are knowledgeable in different areas pertaining to wood fired ovens. How it works:
- Each AMA will have a "sticky" thread where the community can post questions they would like answered during the live session. This will allow everyone to participate even if you can't be online for the live session. These questions will not be answered by the host until the live AMA; if you need an answer quickly, you should post it in the appropriate Forum area for the community to respond.
- Another thread will be posted for the live AMA. Registered users who are logged in during the live session can interact with the host by asking questions and receiving responses.
- The live thread will remain in the AMA forum to view after the session.

To kick off our AMA feature, we have invited author, chef and master bread maker and host of Pizza Quest, Peter Reinhart, to be our first host! Peter will be in the Forum on Monday, February 15th, from 7:00 - 8:00 pm EST. If you are unable to be online during the live session, you can post your questions in the sticky post. Peter will answer those questions during the live session on February 15th. You can view Peter's answers to your questions as well as what happened during the live session in the session thread.

We hope you enjoy this new feature! Please let us know if there is a topic that you'd like to have as an AMA and we'll look for a host!

  • Building second oven

    We are building a second oven for commercial use. We want to make it 1800 mm inside diameter. The oven plans only show dimensions for a 36" (914 mm) and 42" (1066 mm) ovens. We want to build the low vault version. These plans show the interior height, opening width and opening height increasing 1" for the 6" of increase in interior diameter.

    Does anyone have experience with a larger version as far as these dimensions are concerned?

    This oven will be built in a restaurant where we expect to sell between 250 to 400 pies a day with roughly 40% 11" pies and 60% 16" pies. We have access to fairly high grade had wood, a fruit wood of some sort. The restaurant is in a new mall and we will install a spark filter/arrestor on the oven so the hood fan only get smoke - fairly white.

    Our calculations suggest an interior height of 21" (533 mm), an opening width of 23.5" (596 mm) and an opening height of 15.5" (393 mm). Will be very appreciative for information and corrections on these dimensions and any other comments on commercial use of this design for ovens.

    Re: Building second oven

    Wow, that's a big oven! That big and that low an oven will have to have serious side buttressing to counteract the sideways forces involved. I would recommend reading and understanding this page:

    Auroville Earth Institute, training courses, workshops on Vaults, Arches, Domes(VAD), stabilized rammed earth walls, compressed earth blocks, vaulted structures, compressed stabilised earth blocks, rammed earth.

    which discusses the forces involved in arches and domes.

    To answer your question, I don't think anyone here has built the size and shape of dome you're proposing. You might want to consider asking this question on the professional pizza forum:

    PMQ's Think Tank :: Index

    They might have some specific experience with huge ovens to share.

      Thanks much. Have downloaded calculations pdf and posted the question on the PMQ think tank site.

        Dutchoven built a restaurant oven that, although not quite as large as the one you're proposing, was still quite a bit larger than the average here, with a somewhat low dome. you should check out the thread; it's pretty good.

        My oven build is finally complete!
