Product Description

BVT-DLB steam attemperator

Attemperation is used for controlling the degree of superheat in a Heat Recovery Steam Generator (HRSG) or a boiler. Water is injected into the steam pipe using a series of spring loaded atomizing nozzles. Attemperators are installed between the superheater stages in order to protect any secondary superheater pipes from damage owing to excessive heat, called “inter-stage”. Another attemperator is often placed after the boiler / HRSG to regulate the output temperature of the boiler / HRSG or to ensure that the temperature upstream the turbine does not rise too quickly. The BVT-DLB has a welded flow profiling liner for superior evaporation and performance.

Key features

• Very high reliability due to being able to handle thermal cycling
• Flow profiling liner as standard
• Designed to handle large spray water flow
• Nozzles resistant to flashing
• Water atomization pressure is maintained at each nozzle at any flow condition
• Even distribution of spray water in the steam pipe
• Negligable pressure drop in the steam line
