Description

Steam turbine and boiler protection at steam turbine trip. Steam turbine bypass to cold reheat or condenser while boiler/turbine start-up and shut down

Features
– Pressure reduction by multi-stage controlled expansion.
– Atomizing steam desuperheater, providing short evaporation length and protection of downstream piping against thermal shock.
– Subsequent adjustment to changed operational conditions possible due to easily exchangeable trim and seat.
– Spring-loaded packing for long term leak tightness
– Pressure seal bonnet
– Order–specific optimization of trim flow areas and desuperheate
– All actuator types can be used
– Optional: Pre–warming and condensate drain Studs
– Pressure balanced trim with pilot plug and cup springs
