Project Description:
This was my portion of an extra-credit assignment in Thermodynamics. I looked at the real world efficiency of several gas turbines compared to the theoretical values. More specifically, I looked at the efficiency of a GE6FA, GE7FA, and GE6B, and how pressure ratio and combustion temperature could affect the thermal efficiency and power output of the turbines. I used MATLAB to perform the calculations and plot the data. I also sourced a lot of technical data from GE, and personal experience at the Tracy Generating Station with NV Energy, which had a GE6FA and other gas turbines. In addition to this data, I also looked at the efficiency of these turbines, the pressure ratio, and how it relates to fuel usage.
Project Results:
The results showed the importance of being able to increase the temperature at which these engines operate, and the affect of pressure ratio on the outputs and thermal efficiency of these engines. It also showed that different engines are tuned slightly differently in respect to how they balance power output with efficiency – as the most efficient setup does not necessarily produce the most power. There are also clear diminishing returns, and compromises must be made.
