Abstract

795,007. Generating steam by reduction of pressure; superheating. ELECTRICITE DE FRANCE-SERVICE NATIONAL. Oct. 7, 1955 [Oct. 16, 1954], No. 28678/55. Classes 123(2) and 123(3) [Also in Group XXVI] In a power-generating system liquid is heated under pressure and then a fraction of it is subjected to a reduction in pressure to produce steam that is superheated by heat transferred from a further fraction of the heated liquid, the resulting superheated steam being used to drive a prime mover In the plant shown in Fig. 1, water is pumped by a pump 3 through a heat exchanger 2 where it is heated by hot gases f and discharged via a pipe 5. A part of the heated water is fed into an evaporator 6 where it is partially vaporized by a reduction in pressure, the steam so produced being superheated by a further part of the heated water flowing through pipe 7a into a superheater 7 and then led by a pipe 8 into a turbine 9. The water from the evaporator 6 is led by a pipe 11 into a second evaporator 12 where it is partially vaporized by a further reduction in pressure the resulting steam being superheated by the hot water in a second superheater 13 before passing through pipe 14 into the turbine 9. Similarly, the water from the evaporator 12 is vaporized in a third evaporator 16, superheated and fed by a pipe 18 into the turbine which drives an electric generator 10 and exhausts into a condenser 19 whose condensate is extracted by a pump 20 and delivered together with the water from evaporator 16 to the suction side of pump 3. The amount of superheating is controlled by valves 22, 23 and 24 controlling the amount of hot water pasing through the superheaters to the evaporators. In a modification, Fig. 3 not shown, having two evaporators and an H.P. and L.P. turbine, the superheated steam from the first evaporator is expanded in the H.P. turbine and then led into the second evaporator where it is superheated together with the steam produced by the partial vaporization of the water from the first evaporator and fed to the L.P. turbine.
