this air compressor
. The air compressor has a
sleeve, crankshaft and pulley which become the primary moving parts in
a steam engine. Unbolt the compressor's head (6 bolts). Bolt on
the slam valve head. Bolt the unit
down. Plumb in high pressure steam, plumb out waste steam.
becomes an engine. Use a 3 inch pulley to drive a 3600 RPM 1
horsepower or below pump (>355 deg F boiler no
vacuum), or a 6
inch pulley to drive an induction motor at 1800
RPM. If the
intake is at 400 deg F (200 psi) and the exhaust is at
atmospheric pressure (212 F), use a 1 horsepower induction
motor as a generator.
For 350 deg F boiler, use a 3/4 horsepower motor.
running a vacuum system, drop the motor horsepower by half every 25 deg
C drop in radiator temperature (absolute radiator pressure drop of
1/2). Have a mechanism to purge water and emulsion from the
crankcase and use steam oil. We suggest you purchase a spare
compressor. Its cheap, easy to replace, and although its an
sleeve and long lifespan low RPM design, it will still wear out before
the head. All in all an excellent workhorse engine for your
solar thermal power plant or solar powered pool pump. Arrives
tuned for 600 RPM operation, can be tuned for higher RPM. No
torque control as delivered, can be retrofitted for screw or flap type
torque control. Anodized alumimum, 3/8 inch NPT input port, 1/4
inch NPT purge port, two 3/8 inch NPT exhaust ports.
