FIELD: turbines or turbomachines.
SUBSTANCE: invention relates to NPP steam turbine plant. Plant comprises a steam turbine with high-pressure cylinder 1 and low-pressure cylinder 2, separator 3, intermediate superheater 4, electric generator 5, condensers 6, condensate pumps 7, low pressure heaters 8, recirculation of the added working medium 9, hydrogen-oxygen combustion chamber 10, catalytic recombiners of unreacted hydrogen 11 and 12, magnetic separator 13. Elements of the plant are connected in such a way that a combination of catalytic afterburning and action of a magnetic separator is provided during circulation of the working medium: afterburning of unreacted hydrogen with oxygen takes place in catalytic recombiners, moreover, in the magnetic separator, due to the influence of the inhomogeneous magnetic field of the solenoid, the possible remaining amount of unreacted hydrogen is additionally removed by sorption in body of palladium alloy membrane. Possible remaining unreacted oxygen is removed by a system of ejector pumps.
EFFECT: almost complete removal of unreacted hydrogen is achieved and reducing the concentration of unreacted oxygen in the working medium of the NPP steam turbine plant while maintaining the rated operating life of the working blades of the NPP turbine.
