OSC77FD120TH Mini Steam Power Plant

Model: OSC77FD120TH

Features

– This is a benchtop unit for a small low cost miniature power plant designed for educational purpose
– A small gas-fired boiler supplies steam to a single cylinder, double-acting reciprocating engine
– A small DC generator is connected to the engine by a belt and an electrical load is applied using small light bulbs
– Exhaust from the steam engine is condensed in a water-cooled condenser
– Condensate is collected for weight measurement and is returned to feed water tank
– A manual feed pump supplies feed water to the boiler
– Instruments are provided for monitoring and controlling the plant operation and performance as well as for safety

Typical Experiments

– Fuel consumption
– Efficiencies for boiler, engine, and overall plan
– Condenser heat transfer coefficient
– Heat balance and energy utilization
