There are only burner holes along the two outside tubes, how is that even heating?
There are 2 lines of burner holes along the outside tubes and 2 lines of burner holes across the middle H cross section. They are all burning very evenly and steadily. Think you can see this in the picture I posted at reply 149. Lighting the burner is usually a one spark affair but occasionally it helps to waft the flame along - for that reason I would not be happy to put it in a hidden area of the oven. The 2nd problem that I see is that it is not putting out 120,000 Btus - The Weber burners, although smaller, can put out about 32,000 Btus. This is due partly to the size and position of the holes, with feeder ports maybe, which are precisely placed using computerised machinery. As of this time I don't know how much I can get out of my burner until I attach a blower.
My continued repeating you want multiple low pressure burners and manifold??
I presume you are suggesting multiple line burners as in the blogett photo that Scott posted. The more burners the better, I agree. The problem is having a reliable ignition system. I don' want a line of flames along the front of the oven in order to light the other burners running perpendicular to the face - I think that will cause uneven heating. If you have a design that you think will work I'd love to see it and maybe get it made up here or the next time I'm in Bangkok.
I'm trying best to help you out using laymen's terms but you seem to keep changing the system willy nilly and jumping from one concept to another and leaving me to do more work at surmising what you intend to say at any given point on this thread.
At the start of the thread I thought I'd made it pretty clear that I didn't know anything about how a pizza oven is put together let alone how to make a burner. The biggest breakthrough for me was when Scott gave a 3 box analogy, insulation, burners, cooking box. I'm a lot closer now to knowing what I want to build.
After 33 messages it appears all that was accomplished were typing lessons. So what purpose did this serve?
Sorry if you feel like you've been throwing pearls at swine. I am learning stuff!!
Sorry if I come off as cross.
Again just want to let you know that I appreciate all the info you've given so far. Went to the place that sells the control systems today and they had none in stock and none on order! When I make some progress this end I will let you all know.
