Course Objective

The goal of this course is to become prepared for professional engineering design

of conventional and alternative power-generation plants. The learning objectives include

• Analysis and preliminary design of the major systems of conventional fossil-fuel steam-cycle power plants.
• A working knowledge of the basic design principles of nuclear, gas turbine, combined cycle, hydro, wind, geothermal, solar, and alternate power plants.
• Awareness of the economic, environmental, and regulatory issues related to power generation.

Course Outcomes

At the end of the course students are able to:

• Understand the concept of Rankine cycle.
• Understand working of boilers including water tube, fire tube and high-pressure boilers and determine efficiencies.
• Analyze the flow of steam through nozzles
• Evaluate the performance of condensers and steam turbines
• Evaluate the performance of gas turbines
