Solutions for many applications such as chemical and power plants.
NEM Energy Group Heat Exchanger Solutions are using the famous Balcke-Dürr brand, already active since 1883.
Balcke-Dürr is one of the most experienced suppliers for power, chemical and industrial plants. Over the years they have played a significant role for important industrial developments. The product portfolio covers a wide range of heat exchangers and reactors. Solutions for many applications such as chemical and power plants.
High engineered products
- Individual and customized solutions
- Challenging thermodynamic design
- Highly stress- resistent components
- Thermoelastic equipment in cycling mode operations
- Fully integration into existing systems
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.
The WHRU is developed on the same design platform as the Vertical OTSG/DTSG which are used for steam generation and are described below. The vertical gas path design of NEM offers unique modularized construction philosophy resulting in reduced installation time and costs. This modular philosophy applies to our entire design platform in this range.
- 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
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
Moisture Separator Reheater (MSR) & 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 implemenation 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 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
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
Wheater it’s nuclear or geothermal or other fields of energy. NEM Balcke-Dürr Heat Exchangers are applied throughout the whole energy landscape.
