FIELD: power engineering. ^ SUBSTANCE: invention can be used in high pressure regeneration systems of power station steam turbines. Proposed system (version 1) includes one or several chamber heaters with water inlet and outlet branch pipes and tube plate, with lower water chamber equipped with drain branch pipe. First of heater is connected with intake valve with bypass line, and the last, with check valve. Air outlet unions are installed on horizontal and vertical sections of water outlet branch pipe at outlet of regeneration system devices. Steam turbine high pressure regeneration system (version 1) includes one or several chamber heaters with inlet and outlet branch pipes and tube plate, with lower water chamber equipped with drain branch pipes, first of heaters being connected with intake valve with bypass line and the last, with check valve. Hole in made in tube plate with air outlet union in upper part of water chamber higher than upper generatrix of water outlet branch pipe. Steam turbine high pressure regeneration system (version 3) includes one or several chamber heaters with water inlet and outlet branch pipes with tube plate, with lower water chamber equipped with drain branch pipes, first of heaters being connected with intake valve with bypass pipe line, and the last, with check valve, and hole is made in chamber wall with union to let out air in upper part of water chamber higher than upper generatrix of water outlet branch pipe. Steam turbine high pressure regeneration system (version 4) includes one or several chamber heaters with water inlet and outlet branch pipes and tube plate, with lower water chamber equipped with drain branch pipes, first of heaters being connected with intake valve with bypass line, and the last, with check valve. And outlet compartment of water chamber being provided with air outlet branch pipe whose upper cut is located higher than generatrix of water outlet branch pipe. In proposed high pressure generation systems unions can be connected with point in system where pressure is lower than atmosphere pressure, for instance, with condenser. ^ EFFECT: improved economy and reliability owing to removal of air from devices, provision of normal operating conditions. ^ 7 cl, 4 dwg |
