Energy Systems
Modeling and Simulation
Modeling and simulation of solid fuel conversion play
an important role in several projects, e.g. HotVeGas and
SNG. Computational fluid dynamic (CFD) simulations are
applied in order to gain a more detailed understanding of
several combustion and gasification processes. Further-
more, entire process simulations aim at evaluating the
complete power plant system and possible synergies. As
the flexibility of power plants gets into the focus of the
operators – in addition to efficiency and economy – the
interaction of power plant processes during dynamic
operation is investigated by means of dynamic simulations
of power plants. An improved process understanding
helps to develop better operating strategies and optimized
power plant configurations. Two different power plant
types are investigated: combined cycle power plants
and coal-fired power plants. The use of heat at low
temperatures, like waste heat and geothermal heat, with
organic Rankine cycles (ORC) or the Misselhorn cycle is
also a focus of research and is examined at the institute
by means of process simulations and experiments. Since
2016 several projects regarding process simulation have
started: The CleanTechCampus Project, for example, aims
to improve the CHP plant on site. The Bavarian Geother-
mal Alliance focuses on efficiency enhancing designs of
ORCs in combination with suitable working fluids and
possibilities of flexible heat decoupling.

The primary objective of the work at the institute is to lay
the necessary foundations for the long-term development
of future, highly efficient high-temperature gasification
processes with integrated hot gas cleaning and optional
CCS for IGCC power plants and processes for the develop-
ment of synthetic fuels. Further projects, like the EU project
OnCord, which is coordinated by the institute, investigate
the use of coal and its inorganic constituents as a protec-
tive agent to prevent the formation of alkali metal chlorides
at both laboratory/test rig and industrial scale.
