Gas Turbine Facilities (Auxiliary Power Unit)

The facilities currently have two gas turbines (Auxiliary Power Unit). Details of both gas turbines are listed on this page.

Honeywell GTCP85 Auxiliary Power Unit

APU1APU2

The test bed gas turbine engine is a re-commissioned Honeywell GTCP85 Auxiliary Power Unit (APU). The engine test bed facility provides an ideal experimental platform to evaluate the performance of different alternative and conventional fuels on a modern gas turbine engine. The rig fits in the range of possible combustion analysis between laboratory bench scale testing of fuels, of the order of a litre of fuel, and full engine tests, requiring 1,000s of litres. This has advantages in sourcing sufficient quantities of fuel for testing and the possibility of running several fuels back to back, through one test engine. The APU is housed in a test room at the Low Carbon Combustion Centre of The University of Sheffield, with an air inlet and exhaust duct system because of operational noise and safety concerns. The engine is located in the centre of the test chamber with the engine control panel, data logging computer, fuel system and exhaust sample lines located outside the laboratory. The APU could be controlled to run at various power settings. A data acquisition system is used to log a complete set of engine operating parameters.
The following are general specifications for the APU:
• Bleed air flow: 58 kg/min @ 220 °C exhaust gas temperature (EGT) and 0 kW shaft work,
• Maximum shaft work: 149.2 kW

The unit has been configured so that it can run on a variety of fuels and recently it has been used for Federal Aviation Authority (FAA) funded CLEEN project. This has advantages in sourcing sufficient quantities
of fuel for testing and the possibility of running several fuels back to back, through one test engine.

Additionally APUs are one of the principal sources of particulate matter emissions at airports, results generated on this test bed can be compared with a range of fuels already tested and can be used to
assess the improvement in PM (Particulate Matter) emission possible with alternative fuels.

Rolls Royce Artouste

Rolls Royce Artouste Auxiliary Power Unit A small Rolls Royce Artouste Auxiliary Power unit (APU) is the integral part of our Gas Turbine Engine Facility and has been utilised for alternative fuel evaluation, and is sited in its own sound-isolated area. This unit will be able to be externally controlled and monitored from the main University. The engine is rated at 60kW and has a capability of delivering 1.25kg/s of compressed air. The unit has been configured so that it can run on a variety of fuels. Future work will see it developed to be powered by fuel produced by the gasification plant available within the centre.
