Desuperheaters
Ring Style Attemperator
As with any superheated steam cycle, the
temperature of the superheat needs to be controlled
to ensure that it does not exceed the material
limits of the steam turbine and boiler. Temperature
control is accomplished by use of an attemperator
or desuperheater that injects a controlled amount of
cooling water into the superheated steam ow.
Fisher ring style attemperators are designed to work
in conjunction with supporting superheat and reheat
control valves to provide optimal steam temperature
and stability. This prevents damage to the turbine
and extends service life.
