|Mini Propane Burner & Regulator Plans
needed the ability to adjust flame size over a wide range and to be
able to "set it and leave it" for a half dozen or so engines that I
have running at shows and not have one of them run out of fuel and come
to a stop while I was talking to builders like you.
I also wanted the ability to have a sideways flame for my "Sideshaft"
and "4-in-1" Vacuum Engines and some future projects. These low
pressure burners have an air adjustment that allows control of the
flame (yellow tipped - to blue with an intense light blue inner cone)
as well as the flame size.
is also design information and a cut-away drawing of a neat and compact
pressure regulator. Gas pressure can be adjusted from zero to more than
the burner needs - about 8 lbs. per square inch. There is also a parts
layout for an excess flow valve which will permit safe use of flexible
tubing rather than piping to supply gas to the burner.
You can have accurate speed control of your stirling and atmospheric
engines. Also, your atmospheric engines will stay clean inside instead
of getting gummed up from using an alcohol flame. A $2.00 bottle of
propane will operate a burner for around 70 hours! You and your
"hot-air" engine projects will benefit from being operated with a
powerful mini propane burner that is only 2" high!
1/8" bore x 1/4 OD silicone tubing should be used with the burners. The
burners can get fairly warm in use and the vinyl aquarium tubing or
other plastic tubing that you might be inclined to use to connect the
burner to the propane source will soften and may come off the burner
hose fitting. The silicone tubing is very soft and flexible, will
withstand the temperature of molten solder, really clings to metal hose
fittings and will not take a set or become hard with age. Hobby shops
that sell model airplanes and engines will have this.
The plans set consists of 3 sheets of drawings and a sheet of
construction and assembly notes.
your plans, thanks. Excellent quality. They are much better than the
usual sort of rubbish I find in the UK." - Danny Quinlan (Brentwood,
