Likely the reason you don't find much via internet searching, is because a ribbon burner in a vertical forge is WAY overkill in terms of time/materials/complexity, and cost to operate.
Not saying it not doable/useful, its just that most prefer/do go the route of a single, correctly sized blown burner. It's just all round simpler/easier to build, takes less time to assemble install, and uses far less fuel in a vertical forge application.
