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 ser vice 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.

Deaerating condenser in 785 MW Castellon CCPP, Spain
Competence in engineering and fabrication of condensers for more than 100 years Equipping of power plants with capacities from approximately 100 to 1,400 MWel and more 2
Cooling surfaces up to 45,000 m per condenser shell Output raised in existing power plants through modular condenser change-out Optimizing the “Cold End” (condenser, cooling tower and cooling water circuit) Configuration concepts for turbines with vertical and horizontal exhaust steam flow Special constructions such as deaerating and geothermal condensers Patented tube bundle with performance-optimized design (TEPEE) Patented tube configuration for maximum wet steam erosion resistance
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 numeric al 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. Static pressure relative [Pa]
