Thermal Power Plants
Bachelor degree course
Environmental and Energy Process Engineering, Industrial Engineering for Chemical and Energy Engineering.
Module
Thermal power plants
Objectives of the module
Students are able to calculate key performance and evaluation parameters including the thermal efficiencies of the different processes for producing mechanical power from heat. The students know everything about the advantages and disadvantages of the method as well as their economic conditions. The method can be evaluated ecologically in terms of energy consumption and CO2 emissions.
