DAM-H High-temp Multi-nozzle Desuperheater
High-temp multi-nozzle desuperheater with floating liner
The DAM-H desuperheater is designed for attemperation in high-temperature applications, such as controlling the superheat degree in boilers or Heat Recovery Steam Generators (HRSG). This desuperheater features a controlled injection of water into the superheated steam, ensuring precise temperature control. Its floating flow profiling liner (patent pending) is designed to improve evaporation performance and handle thermal cycling, making the DAM-H a highly reliable solution for demanding steam systems.
- Floating flow profiling liner (patent pending) for enhanced evaporation performance.
- Designed to handle large spray water flow quantities efficiently.
- Even distribution of spray water within the steam pipe, ensuring reliable operation.
- Negligible pressure drop across the steam line.
- Nozzles designed to prevent flashing, enhancing operational safety.
- High resistance to thermal cycling for long-term durability.
