This is an experiental or laboratory model steam pc'
plants built to determine the general feasibility of fractional
horse-power portable, units for generation of" electricity.
The burner is designed to use col erciel or aviation
gasolines, or pressure appliance fuel commonly referred to as
*White ga9.. it is of the "instant start tnge type as used on
gasoline camp stoves, in which aerated or vaporized fuel, ejected
under pressure from a nozzle, entrains air for combustion and
forces the combustible mixture through a burner plate, above which
combustion occurs.
The boiler is of the continuous coil semi-flash type, in
which feed water entering at one end of the coil in progressively
heated and converted into saturated steam, and this saturated steam
is in turn superheated. The rate at which fuel is burned is auto-
matioallly regulated as a function of - steam pressure. The rate at
which water is fed into the boiler is automatically regulated as a
function of temperatures in the first part of the superheater section.
The engine is of the Unaflaw type,, two cylinder, single
acting,: 1.4./ bore x 1.-1/8" strt e , with automatic Internal inlet
valves and eccentric operated auxiliary exhaust valves. A p p
unit mounted upon one and of the engine crankcase embodies two
feed water pumps,, one fuel, pumps one hydreculic governor unit and
one lubricating oil pump.
For non-condensing operation, the exhaust steam from the
engine is discharged to atmosphere. For Partial condensing operation
the steam is discharged in a foldable air-cooled condenser which is
rigged above and behind the carrying cam. Condensate from this
unit is returned by gravity to the water supply tank.
To furnish some self-contained method of absorbing and
measuring engine output on this experimental unit, a pair of
available 125 watt 134 volt 400 cycle permanent magnet alternators
is combined on one shaft in unaiynchronized relationship. Since these
turn at 4800 r. p.m. and the normal operating speed of the engine is
about 2200 r.p.m., an elementary atop-up friction drive from engine
crankshaft to alternator shaft is provided. This drive must be
regarded solely as a temporary expedient and not suitable for non-
tinuous use. Since the alternators are not synchronized, their
external output connections are brought separately to the outside
of the carrying case.

TEST PERFORMANCE
The performance curves plotted above are based upon averages of about a
dozen test runs, each of 15 to 30 minutes duration.
Individual teat runs gave values of water consumption, fuel consumption
and water rate varying as much as plus or minus 10,E from the average,
depending upon combustion efficiency, steam temperature and pressure.
valve timing, condition of piston rings, lubrication, jacketing,
The (Water-Consumption vs. Horsepower" curve shows the net amount of
water collected and condensed from the exhaust with a water cooled test
condenser. The actual amount of water 10~ pumped into boiler,
and delivered as steam may be 5% to
as leakage past valve packings and blow-by past piston rings.
