Thermal Energy Technology

Integrated course, 4.00 ECTS

 

Course content

After a repetition of the relevant basics we focus on technical and operational aspects of thermal energy technology. The therefore necessary theory (thermodynamics, fluid mechanics, heat transfer) will be repeated during the lecture. Example calculations complement lecture content. In addition to that, we include currently discussed themes about society and politics as far as they are relevant for energy technology.

Contents:

  1. Boundary conditions:
    Repetition of energy conversion basics, energy economics, KPIs...
  2. Physical und chemical basics:
    Fuels, combustion, emissions, heat transfer in heat exchangers, pressure losses, water and steam as a working fluid
  3. Thermodynamic cycles:
    Heat engines, heat pumps/cooling processes
  4. Historical developement of heat engines
  5. Rankine cycle:
    Improvement potential, components (combusters, steam generators, steam turbines, condensing- and cooling-systems, feed water supply)
  6. Piston engines (Otto, Diesel, Stirling)
  7. Gas turbine and combined cycles:
    Brayton cycle, Gas turbine, combined cycle (STAG)
  8. Cogeneration and district heating systems:
    Cogeneration (CHP), district heating

Learning outcomes
