Ribbon burner build

[RBuckson]

I see most if not all ribbon burners are made with a 2 inch or maybe 1 1/2 piping going into the mixing chamber. Well 2 inch is a pain in the ass to find and/or costs is ridiculous in my area. So my question is would I lose or gain anything if from the blower fan I start reducing down to 1 inch piping and place two 1 inch air/propane outlets into the mixing chamber. Of course I would have needle valve for propane and gate valve for air. But would reducing from 2.5 inch fan down to 1 inch piping into chamber be smart. Ribbon burner chamber is 3x3x10 New here so any advice would be nice.

Can’t answer but I ordered a new ribbon forge and it should be here soon. Not sure the sizing.

Chuy of yeti forge in Tucson AZ sells parts for building. U could try him.

It depends on the fan/ blower and the total burner port area, among other things. There are way too many variables to be able to give an easy answer in a forum post.

Area is the factor to consider. To get the same area as a 2” pipe, you’d need 4-off 1” pipes.

2-off 1” pipes have about the same area as a 1.5” pipe.

If you calculate the total area of the holes in your burner block and keep the minimum pipe area significantly above it, you are unlikely to have a problem.
