TH 150 MINI GAS TURBINE POWER PLANT
GENERAL DESCRIPTION

The turbine is an educational mini gas turbine power plant with a radial flow compressor and axial flow turbines, gear box, generator, and electrical loads as in 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 ignighted 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 The gas generator runs on ceramic bearings. A fan is provided for cooling the engine.

The power turbine output shaft is connected to the gear box. An AC generator is connected to the gear box. Electrical power output is from lamp loads.

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 load control, data display and analysis, and to assist the ECU.

Safety features include shut down for gas generator or power turbine over speed, and power turbine entry over temperature shut down. The unit is floor standing with removable supports.

TYPICAL EXPERIMENTS
  • Understanding the thermodynamic process.
