Description
The unit is supplied as two complimentary modules. An independently certified electric boiler with safety valve, automatic control system and fail safe pressure switches, provides steam at up to 8 Bar gauge to a solenoid valve. This in conjunction with an optical sensor limits the maximum turbine speed to a safe level. Steam flow to the turbine can be throttled by a hand valve and the boiler, turbine inlet and condenser pressures are indicated on gauges. The impulse turbine is driven by a convergent divergent nozzle and turns a brake wheel with speed sensor and digital indicator allowing true shaft power to be determined. An optional electrical power generator is also available for demonstration purposes. The turbine exhausts into a condenser and this passes water to a similar water reservoir. The reservoir connects to a boiler feed pump. Like full size real power plant the condenser operates at subatmospheric pressure and the unit incorporates an air extraction system. The boiler feed pump and non-return valves to the boiler complete the full Rankine cycle. Instrumentation includes all relevant system pressures, system temperatures, and cooling water flow rates, turbine speed and brake load. A combination of digital and analogue displays show the recorded parameters.
