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

TECHNOLOGY<br />
Our turbine condensers are equipped with TEPEE tube bundles.<br />
Depending on the tube material, this highly effective design is up<br />
to 20 % more efficient than the HEI Standard and offers significant<br />
benefits:<br />
■ Increase in power plant output as lower condenser pressures<br />
can be achieved.<br />
■ Savings in respect of capital expenditure costs as smaller<br />
cooling surfaces can be installed.<br />
Cross sections through TEPEE tube bundle<br />
The shape of the tube bundle reminiscent of an American Indian<br />
tent (“Tepee”) is the result of numerous experimental and numerical<br />
studies. It generates an ideal steam flow with minimal pressure<br />
drop, high condensation rate and effective deaeration.<br />
In-house programs which are backed up by results measured<br />
in practice are used to construct condensers with an optimal<br />
thermohydraulic design. The application of the very latest 3D CAD<br />
software ensures faultless engineering.<br />

Our manufacturing facilities use proven QA programs with virtually<br />
fully automated production processes to ensure long-term troublefree<br />
condenser operation.<br />
