Turbine Condensers

Streamed for high performance:
TURBINE CONDENSERS
Balcke-Dürr turbine condensers are rated among the most
efficient in the world. Decades of experience in the construction
of condensers, during which the products have been constantly
optimized in close cooperation with power plant operators, also
stand for a high degree of operating reliability and top class
workmanship.
Balcke-Dürr has a wide range of water-cooled surface condensers
which cover virtually all ser­v ice conditions in power plants,
irrespective of the type of turbine.
We supply high performance condensers characterized by a tube
bundle design (TEPEE) optimized in respect of pressure drop to
generate electricity with maximum efficiency and to enhance the
output of existing power plants.
For use in combined cycle power plants, we provide innovative
deaerating condensers as a space-saving product solution which
combines the functionality of feed-water deaerators and turbine
condensers in one single component.
We make a valuable contribution to environmental protection
and conservation of resources with a product line developed to
generate energy regeneratively: geothermal condensers.

TECHNOLOGY
Our turbine condensers are equipped with TEPEE tube bundles.
Depending on the tube material, this highly effective design is up
to 20 % more efficient than the HEI Standard and offers significant
benefits:
■Increase
in power plant output as lower condenser pressures
can be achieved.
■Savings
in respect of capital expenditure costs as smaller
cooling surfaces can be installed.
Welding of tube-to-tube sheet joints
Comprehensive competence for jobsite erection, commissioning
and acceptance testing round off our full-service spectrum.
APPLICATION
3x720 MW Majuba 4-6 coal-fired PP, South Africa:
The dual-pressure condensers in operation since 1999 are among
the largest in the world and equipped with 22m long titanium
tubes.
Cross sections through TEPEE tube bundle
The shape of the tube bundle reminiscent of an American Indian
tent (“Tepee”) is the result of numerous experimental and numerical
studies. It generates an ideal steam flow with minimal pressure
drop, high condensation rate and effective deaeration.
In-house programs which are backed up by results measured
in practice are used to construct condensers with an optimal
thermohydraulic design. The application of the very latest 3D CAD
software ensures faultless engineering.
