This is the third superheater made by the nuclear power plant for the past three years.
Separators, steam heaters installed at the station before the end of their design life. It was decided to extend their useful life by replacing the superheater. This equipment is the development of the company’s own design, it is part of the system of separation and intermediate superheating of steam turbine hall NPP turbine plant K-1000-60/1500.
Equipment supplied by Balakovo NPP modernization passed: now used for its production of new material — steel pipe 08H14MF. This steel is not susceptible to intergranular corrosion and not prone to cracking chloride. In addition, the most exposed to erosive wear tube wiring stage I began to be made of stainless steel 08H18N10T. Also, a number of other technological improvements.
Superheater SPP-1000 — the machine room equipment plant. The device internal diameter of 3.4 m, weighing 81 tonnes, is a set of heat exchange cassette consisting of finned tubes produced by the industrial technology, longitudinal fins. Just a superheater 187 such tapes. Wet steam after the high-pressure cylinder enters the separation part of the SPP, is separated and sent to superheat part by tapes, superheated to the required parameters and returns to the turbine.
