Heat Exchangers

Feedwater Heaters

Our feedwater heaters are shell-and-tube heat exchangers that reliably heat feedwater or district heating water by means of steam. We have well proven experience with a wide range of applications enabling us to offer best solutions in regards to reliability and efficiency. We design and manufacture feedwater heaters for nearly all kind of applications.

– Vertical or horizontal arrangement
– U-tube or header type design
– Highest efficiency due to various features (grids, power venting etc.)
– High reliability based on sophisticated engineering
– Up to 300 t maximum weight

Benefits

• Highest efficiency and reliability in designs
• Only supplier worldwide with a complete range of feedwater heaters
• Replacement and rebundling of existing heaters as a core competence

Condenser & Cold End Solutions

Our turbine condensers are rated among the most efficient in the world. Decades of experience in the design and construction of condensers, during which the products have been constantly optimized in close cooperation with plant operators, stand for high degree of operating reliability and top class workmanship.

– Vertical or horizontal arrangement with round and rectangular shell
– Highest efficiency due to optimized and verified tube bundle design
– Cold end solutions incl. NCG Removal, pumps, pipes, tube cleaning system etc.
– For new plants and retrofit with power upgrade of existing plants
– Condenser bundle made of Titanium, Stainless or Duplex material, resistant to erosion
– Applications as nuclear, combined cycle, geothermal, cogeneration and multi pressure condensers for all size of turbines

Benefits

• Configuration concepts for turbines with vertical and horizontal exhaust steam flow available
• Providing a complete cold-end solution, including the condenser, cooling tower, and cooling water circuit, along with their installation
• Increased output in existing power plants through modular condenser replacement

Rotor Air Cooler

The Balcke-Dürr Rotor Air Cooler is an advanced design and solves the stress corrosion problem faced by many gas turbines applications. The innovative, patent pending design, is based on stress corrosion resistant material, elimination of expansion joint and heat protection of critical parts. This protects the cooler against excessive fatigue from thermal cycling and increases the availability.

– Stress corrosion resistant material and design
– Critical parts are specifically designed to eliminate stress
– Failure Free Equipment: No unscheduled maintenance, reduced risk of gas turbine damages and higher availability of the plant
– Straight tube design fits into existing plants and allows simple retrofitting
– Alternative header type design available, enabling highest thermoelasticity

Benefits

• Replacing of existing RACs by maintaining the main connections
• Individual and customized solutions
• Increasing plant’s availability and performance
