FEEDWATER HEATER / DISTRICT 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

MOISTURE SEPARATOR REHEATERS (MSRS) & POWERSEP

As a pioneer of MSR technology since the beginning of nuclear power generation, with an experience of more than 50 years, we provide Moisture Separator Reheaters (MSR) and equipment for moisture separation for new builds, retrofits, and power upgrades in the field of nuclear and solar thermal power plants of virtually any size.

Significant performance increase by the implementation of Balcke-Dürr MSRs in existing plants is proven by several references.

​

– 1 and 2 stage MSRs for horizontal or vertical orientation
– Patented high-efficiency moisture separation

​

  • PowerSep (Pre Separator): external add-on component for moisture extraction upstream of the MSR

  • PowerVane (Fine Separator): high-performance modular vane-type separator

 

– State of the art low finned tubes for increased heat transfer

– High availability of equipment and extended life time by advanced design, reducing erosion, corrosion, and thermal stress

– Optimized integration of the new equipment, also into existing units

 

Benefits

  • Perfected MSR technology based on decades of experience

  • Maximum component protection and power gain thanks to Powerseps

  • Increased efficiency through Powervanes separation technology
