Mini Propane Burner & Regulator
I 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.
There 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 pipeing 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!
The plans show how to make a tiny gas orifice, but I also have
them available ready made for $6.00 on the Project Plans Order Form. They
are brass 2-56 hex head screws with a .006" jet hole drilled
through them. Very few hobbyists have the equipment needed to
make them.
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.
