MAGNETIC SEPARATION OF NON-OXIDISED HYDROGEN GAS FROM MEDIUM OF SUPERHEATED STEAM UNDER PRESSURE USING MAGNETIC FIELD OF SOLENOID AFTER COMBUSTION SYSTEM IN STEAM TURBINE CYCLE OF NUCLEAR HEAT AND POWER PLANTS

摘要

FIELD: nuclear power engineering.SUBSTANCE: invention relates to nuclear power engineering and is intended for use in steam-turbine plants of APS with a system for combustion of hydrogen and oxygen containing under-oxidated hydrogen in the main flow of the working medium under pressure after the combustion system before entering the turbine. Magnetic separator comprises a solenoid and a working channel for transportation of cleaned flow. Main round-section pipeline is a straightforward one and in the inner part of it, in the near-wall area and along the whole perimeter, there is installed a selective membrane made on the base of palladium-silver alloy; it is located in the section of magnetic field impact on the treated flow of superheated water steam under pressure of under-oxidated gaseous hydrogen after the system of combustion within the cycle of the steam turbine plant. On the outer side of the main pipeline there is forseen a connecting with it bleed pipeline for diffused through the membrane separated hydrogen; installed on the bleed pipeline there is a corresponding outlet valve, as well as a sensor of concentration of diffused through the membrane separated hydrogen.EFFECT: technical result: increased efficiency of separation.1 cl, 1 dwg
