I'm about to build a small raku kiln and am confused as to what sort of
propane burner to get. The choices seem to be 1) a weed burner, 2) a venturi
burner, or 3) a forced-air system. What would be the relative advantages /
disadvantages of each? Recommendations?
Many thanks,

Weed burner if you need/want to go cheap. Will work, but has limitations.
Forced air system requires electricity and is overkill for this application.
Venturi burner efficient and flexible.
I got the raku burner system (added safety) from Ward Burner, very pleased.
Here's the link: http://www.wardburner.com/burnersparts/rakuburners.html

Weed burner is inexpensive. BTU output may or may not be sufficient; one
size fits all. Sheet metal construction will decompose fairly quickly with
repeated use. AFIK, they are propane only.
Venturi burner is designed for the purpose. They are typically cast iron,
which is brittle, so don't be swinging them around; they will break. BTU
output (burner/orifice size) can be selected based on kiln size. Moderate
cost.
Forced air burners are _expensive_ , but typically come with all the stuff
you actually should have on the other burners, like a pilot, flame detector,
and safety shutoff. They offer complete control over the atmosphere in the
kiln.

Simple! Make the type of burner which, cost next to nothing, that produces
the amount of BTU needed for a fast heat-up, and stays reliable for ever
and ever! Your answer is at: www.R2D2u.com "The Portable Raku Kiln".
Proven over and over again for years past and years to come!

Ask yourself. "What do the professional raku kiln builders use?"
They use the best burners they can get at a low cost.
That is generally a small (75,000 BTU) venturi burner.

As for me I prefer to build my own burner from pipe fittings.
