| Detailed description of topics:Short recapitulation of the fundamentals of engineering
thermodynamics: first law, energy balance of closed and open systems, second law, entropy
and irreversibility. Thermodynamic properties of fluids: properties of ideal gas,
properties of water and steam.
Definition of exergy. Exergy of fluid flows. Exergy
efficiencies. Exergy losses in open stationary systems. Exergy losses during expansion,
compression, heat transfer, and combustion. Principles of value diagrams.
Analysis and optimisation of conventional (boiler/steam cycle)
power stations: preheating of combustion air; optimisation of main cycle parameters;
optimisation of steam reheat and extraction feed water heating. Alternative working
fluids.
Analysis and optimisation of gas turbine processes (closed
cycle and open cycle processes): effect of main cycle parameters on exergy loss;
intercooling; recuperation and reheat. Combined cycle systems: exergy losses in waste heat
boiler; effect of two and three pressure boiler system; supplementary firing in waste heat
boiler.
Combined heat and power production: efficient use of residual
heat; characteristics of different CHP plants; flexibility with regard to the power to
heat ratio; power to heat matrix.
Characteristics of fuels (solid, liquid, gaseous). Combustion
reactions; heat of combustion. Chemical exergy of gas mixtures, definition of environment.
Determination of exergy of gaseous fuels.
Fuel cells: reversible combustion; electrochemical conversion
of fuel; some characteristics of different types of fuel cells and fuel cell systems.
Refrigeration cycles and heat pumps. Open and closed cycles.
Gasliquefaction processes. Energy transformation by absorption. Thermodynamics of
mixtures. Enthalpy/concentration diagram. Processes in absorption cycles.
