Automated trash racks and trash rakes that deliver reliable water supply for power production
Maintains Consistent Water Supply for Power Generation
Water intakes for power generation often address conditions such as high volume, high velocity, large debris, human refuse, aquatic vegetation, seasonal foliage, or even marine life. Continuous cleaning equipment assures unrestricted water flow at the intake and protects downstream turbines, cooling towers, and traveling water screens from harmful debris. Duperon offers screening expertise and a range of systems to manage the unique demands of power intakes.
- Hydroelectric: Hydropower depends on water in motion to create electricity. As water is drawn from an intake it must be free of debris to avoid damage to the rest of the system. Trashrakes and screens help to remove debris, but ineffective screening can also restrict flow. This creates a delicate balance between the ability to screen out debris and minimize headloss to generate at full capacity.
- Thermoelectric: Cooling water intakes play an important role in thermal power generation. Many facilities use automated screening as a best practice to minimize debris events at their cooling towers. By preventing blockages at the intake, clients can avoid de-ration or shut down for greater system reliability and maximum power generation.
Duperon Full-Screen Cleaning™ cleans all of the screen, all of the time. It addresses debris as it comes in (and can be handled at the deck) and prevents accumulation to keep water flowing. Every cycle cleans the entire intake. This contrasts with transversing-style units that often have blinding that occurs before they can repeat their cleaning cycle, resulting in disrupted waterflow.
The simple design of Duperon screens allows it to reliably perform under a range of debris and flow conditions. The use of durable materials like A36 Steel (coated or hot-dipped galvanized), stainless steel or Super Duplex stainless ensure long product life in coastal and corrosive environments.
Duperon proven screening technologies can provide protection for a variety of thermal and hydroelectric power applications, including:
- Natural Gas
