High pressure cylinder (HPC) complete with stop and control valves for steam turbine K-316-240-3MR, modernisation K-316-240-3MR.

High-pressure cylinder with loop steam movement consists of: cast bodies (outer and inner) with horizontal split, with oblopachivanie; CVD shells with oblopachivanie; one-piece forged high-pressure rotor. Steam distribution - nozzle, steam supply to the DDC is made through two stop valves and seven control valves. The flow part of the DDC is of reactive type and consists of one regulating and nineteen pressure stages of reactive type. The regulating stage and ten pressure stages located in the inner casing form the left steam flow. The remaining nine pressure stages are located in two cages and form the right flow. The design of the DDC is based on honeycomb overband seals.
The DDC is equipped with a system of additional heating of thick-walled elements of the casing (flanges of box-less type), for their uniform heating during start-ups and defrosting during shutdowns.
The total weight of the equipment is 240 tonnes.
