Geothermal Energy: Harnessing The
Abundance Of Earth?

.
• The earth holds enormous amounts of
energy.
• We like to use this energy as we are faced
with an ever increasing demand.
• However, in most places, this earth energy is
hard to reach.
• Yet, in a handful of locations, this energy can
be found immediately below the surface of
the earth, or in some cases, even on the
surfaces.
• Take Iceland for example.
• Geysers regularly eject a mixture of steam
and hot water high up in the sky: free energy.

Challenge / question
• Our client in Iceland would like to use the high
steam pressure of a geyser to produce power.
• This is possible using a turbine.
• The low pressure of steam leaving the turbine
would also be used to warm up clean water for
the capital Reykjavik.
• The client is looking for a condenser, a so called
surface vacuum condenser, to condense the
steam.
• There are two important requirements for the
design of the surface vacuum condenser: the
pressure drop must be extremely small for the
low pressure steam and the enormous forces of
the turbine housing that connects to the
condenser, must remain manageable.

Challenge / question
• In addition, it must be taken into account that the
steam from a geyser, the geothermal fluid, is
anything but clean and will corrode various
materials.
• The material used for the heat exchangers, for
example, must be 254 SMO.
• It is also a known fact that the tube-to-plate
connection could be a weak spot in the system.
• The extreme restart conditions also require
particular attention.

water. A geyser is under pressure. High
pressure.
Our solution
• Years of experience allowed us to design a
surface vacuum condenser with a very small
pressure drop on the steam side.
• This was made possible thanks to a special
design of the low pressure steam duct and a
sophisticated pattern of pipes.
• In order to absorb the forces of the turbine
housing to the condenser, we created
special bellows.
• The condenser can also be hung using
springs which then absorb all the forces.

water. A geyser is under pressure. High
pressure.
Our solution
• We designed the internal construction of the
heat exchangers for the geothermal fluid so
that it is able to accommodate large thermal
expansion.
• This prevents the heat exchangers from
bending during the restart process.
• For the tube to plate connection, we choose
the established and special connection of
Bronswerk®Heat Transfer which prevents
cracks from appearing between the tube and
the tube plate and therefore resolves the
corrosion problem.
• Our welders are able to weld the most
extreme combinations of materials; the
requirements of 254 SMO for the heat
exchangers is mere child's play for them.
