Abstract

778,941. Power-generating systems; steam turbines. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Feb. 4, 1955 [Feb. 8, 1954], No. 3657/54. Classes 110 (3) and 122 (3). [Also in Group XIII] In a power generating plant in which a heat carrier fluid is heated by a nuclear reactor and flows in a closed cycle inclucing boiler plant wherein heat is transferred from the heat carrier to motive fluid, e.g. water/steam, for a prime mover, the temperature of the carrier fluid returned to the reactor is maintained substantially constant under varying prime mover loads by controlling the temperature of the motive fluid in the boiler plant to thereby control the rate of heat transfer. In the embodiment shown the heat carrier is circulated by a pump P1 through three cascaded boilers operating at successively lower pressures and each having an economizer, an evaporator and a superheater, the heat carrier flowing from the reactor first through the superheater, H.P.S. &c. and then through the evaporators H.P. EVAP, &c., and the economizers HPE &c. alternately. Steam passes from the superheaters to respective stages of a steam turbine via safety valves 1, 2 and 3, relief valves 4, 5 and 6, and speed governor controlled inlet valves 7, 8 and 9 respectively. When the turbine load falls its speed increases and the governor closes valves 7, 8 and 9 causing the boiler pressure to rise until the safety valves 1, 2 and 3 operate and pass excess steam to the next lower pressure stage, the L.P. steam being discharged into the condenser. When the turbine demand exceeds the steam available the relief valves 4, 5 and 6, which are back-pressure valves, operate to prevent steam passing to the turbine. By these means the pressure in each boiler is maintained at a predetermined level so that the rate of heat transfer in the boiler plant is substantially constant. The temperature of the heat carrier leaving the boiler plant may be controlled by (1) bypassing some of the feed water flowing to the low-pressure economizer L.P.E. by means of valves 10 and 11, (2) varying the setting of valves 3 and 6, and (3) varying the temperature of the feed water leaving the turbine plant. The latter may be achieved by varying the condenser vacuum or the flow of cooling water or controlling the amount of feed heating steam passing through valve 22 or when bled steam feed heaters are used, as shown, by adjusting supply valves 15, 16 or 17 or by-pass valves 18, 19, 20 and 21. The rate of flow of cooling water may be made to vary in accordance with that of the heat carrier fluid by driving the pumps PI and P3 from the same motor or otherwise coordinating the pump drives. Any of the foregoing control means may be effected automatically by a temperature-responsive device fitted in the heat carrier path and actuating the controls through servo-mechanisms.
