Detailed description of topics:

The objective of the lecture “Thermal Power Engineering ” is develop a thorough understanding of technical options to produce heat and electricity in centralized and decentralized power plants. Boundary conditions which are taken into account are sustainability, environmental impact and economical competitiveness. Possibilities to contribute to the development of highly efficient, environmentally friendly and integrated processes for the production and utilization of heat, power and secondary fuels like hydrogen will be discussed.

The lecture comprises:

1.       Introduction: current developments, requirements, thermodynamics

2.       Scheme of a steam power plant and a combined cycle

3.       Combustion: fundamentals, combustion systems, emissions and emission control

4.       Steam generation: fundamentals, boilers, design of a steam generator

5.       Steam turbine

6.       Cooling system and feed water prearation

7.       Possibilities for efficiency improvement and future developments

8.       Gas turbines and combined cycles for natural gas

9.       Combined cycles for solid fuels (Integrated gasification combined cycle, Pressurized fluidized bed combustion, Pressurized pulverized coal combustion, Externally combined cycle)

10.   Alternative concepts: fuel cells, MHD, CO2 sequestration

11.   Possibilities for Biomass conversion

Remarks assesment, entry requirements, etc.):

·         Linked to (and follow up of) Thermal Power Plants is the calculation of a power plant cycle with the programme CYCLE TEMPO

·         The visit to a thermal power plant is part of the lecture

·         The participation in the lecture and exercise is strongly recommended for the examination.

Learning goals:

Learning to design effective thermal power plants using thermodynamics, fluid dynamics, information from the course material and the recommended literature.

Computer use:

In the Process scheme calculation following on this course, the computer programm Cycle Tempo will be used to make the thermodynamic calculations.

Laboratory project(s):

The Process Scheme calculation after the course has to be completed in about 200 hours.

Design content:

The design of thermal power plants consisting of several kinds of components like: turbines, pumps, condensors, steam boilers, reheaters, preheaters that are connected by pipes and for which thermodynamic optimization is very important.
