Gas Turbine Lab Essay

613 words - 3 pages

The primary objective of this experiment is to gain a better understanding of how gas turbines operates, and the parameters which influence their efficiency.


The Gunt ET972 Small Gas Turbine Demonstration Unit is an educational instrument, designed with ergonomics in mind, and is equipped with a number of displays to convey performance information. Propane is used as the fuel. As small size and a range of options are required in an educational setting, efficiency is not a priority and hence suffers as the unit is optimised for practicality rather than power output.
Gas turbines are effectively vibration free as there is no reciprocal motion as in a piston engine, have a very high power to weight ratio, and when coupled to an electrical generator, are used to account for unexpected rises in power electricity demand.

The above table or results was calculated in Microsoft Office Excel, and utilised the value input on the previous page. A sample calculation(next page), details the method implemented in Excel.

Sample Calculation

The compressor map is an essential tool in predicting the performance, efficiency and optimum operating conditions of gas turbines.

Examining the compressor map, it is clear that that thermal efficiency (ηth) of the Gas Turbine increases with speed. Across the range measured, the relationship was approximately linear, with a maximum thermal efficiency of approximately 16.5%. Although this is extremely low, efficiency is not a primary concern in this operating environment, and the turbine is only representative of an actual system.
