TH 120 MINI STEAM POWER PLANT
GENERAL DESCRIPTION

This is a small low cost miniature power plant designed for educational purpose.

A hand feed pump supplies water form a feed tank to a small gas fired boiler. Steam is throttled 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 and returned to a feed water tank.

Instruments are provided for monitoring and controlling the plant operation and performance as well as for safety.
