ThermodynamicsGas turbines





The unit is an educational two-shaft gas turbine power plant with a radial flow compressor and axial flow turbines, gear box, generator, and electrical loads as in the modern gas turbine power plant.

The first stage is a hot gas generator. Inlet air through an orifice flow measuring device is compressed by a single stage radial flow compressor. The turbine is motor started and runs on Jet A fuel. Fuel is injected by a fuel pump and ignited in the combustion chamber providing hot gas for a single stage axial flow turbine which in turn drives the compressor. The hot gas is discharged axially to a larger power turbine on the second shaft and exhausts to atmosphere. A fan is provided for cooling the gear box.

The power turbine output shaft is connected to the gear box. An alternator is connected to the gear box by a direct coupling. the electrical output is converted by an inverter to 220 VAC and the electrical power output is connected to a lamp load.

An Electronic Control Unit (ECU) controls the basic turbine operation. Additional instruments are provided for monitoring and controlling the plant operation and performance.

A touch screen computer with an interface unit and software are provided for speed and electrical load control, data display and analysis, and to assist the ECU.

Safety features include safety guard, gas generator over speed shutdown, power turbine over speed protection, power turbine entry over temperature shut down and emergency switch. The unit is floor standing with removable supports.
