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.
