Brayton Cycle: The Ideal Cycle for Gas-Turbine Engines
In Relation to Power Plants
Power generation is an important issue today, especially on the West Coast. Demand is outweighing supply because of lack of incentives for the utilities industry to build additional power plants over the past 10-20 years. Electrical innovations (such as the personal computer) were not accounted for in earlier predictions of power utilization and, now, the country is in dire need of streamlining the current power plants while pushing through as many applications as possible for new power plants. In response to this situation, power generation engineers will be in high demand. These engineers must have a thorough understanding of thermodynamics and, in particular, the Brayton cycle. It is the backbone of power generation. In order to deepen knowledge of how the Brayton cycle is applied at power generation plants, an interview was conducted via e-mail with Brian Lawson, who has obtained the P.E. designation and is the Senior Mechanical Engineer for Sierra Pacific Power Company’s Tracy Power Generating Station. This station provides a total electrical power output of 454 MW and supplies the majority of the population in northern Nevada. The italicized questions and answers asked and obtained are integrated throughout the various topics to provide further insight and understanding for the beginning engineer entering the power generation field. Further, bolded words are defined in detail at the end of each paragraph.
