Course content

Thermodynamic basis for power and cogeneration cycles. Models and design practice for components like gas turbines, steam turbines, boilers and condensers. It will be emphasized on topics like system selection/configuration, economical considerations, adaptation of components, and off-design and part-load behaviour of components and systems. The use of alternative working fluids for air in Brayton cycles and water in Rankine cycles. Novel cycles are discussed. Control philosophies are discussed. Environmental aspects and methods are discussed. Processes with CO2 capture are discussed.

Learning outcome

The course provides the student with knowledge about:
• Gas turbines, both with respect to thermodynamics and fluid mechanics
• Steam cycles, both those for combined cycles and those for conventional cycles with fired boilers
• Cogeneration of heat and power in power plants
• Off-design and part-load for gas turbines
• Off-design and part-load for steam turbine cycles
• Off-design and part-load combined cycles
• Principles for control of gas turbines and combined cycles.
• Investment costs for thermal power plants
• Reliability and availability
• Simulation of gas turbines, steam turbine cycles and combined cycles
The course gives the student insight about:
