Abstract

1,204,119. Vapour turbine power plant. NATIONAL RESEARCH DEVELOPMENT CORP. Dec.22, 1967, [Sept.22, 1966], No.42422/66. Headings F1Q and F1T. In a power plant having at least two vapour cycles the vapour after expansion through a turbine in the primary cycle is in an appreciably superheated condition, the heat of de-super-heating being used to provide at least the major heat input to a secondary cycle. In one embodiment, the working fluid of the primary cycle is a high molecular weight fluid such as perfluorodecalin (P.F.D.) or hexafluorobenzene (H.F.B.), while that of secondary cycle is benzene and/or a refrigerant known as R-11. In such a system the P.F.D. is vapourized and highly super-heated in a primary boiler B, using gas turbine exhaust heat, before expanding through a high temperature turbine H and giving up most of its superheat exchanger HE1 to vapourize the benzene flowing in the secondary cycle. The P.F.D. is condensed at C1 and pumped back to the boiler B, whilst the benzene vapour expands through a lower temperature turbine L before condensing at C2. A second heat exchanger HE 2 may be provided to transfer heat back to the primary cycle. The turbines H, L drive an alternator A and feedpumps FP 1 and 2. The flow of the cycles are arranged so that the temperature difference between the primary and secondary fluids is substantially constant throughout the heat exchanger HE1. In a modification, the secondary cycle also uses P.F.D., in which case the primary and secondary cycles may have a section where the flow is common, Fig.4 (not shown). In further modification, Fig. 8 (not shown), a third cycle is provided, the primary and secondary cycles using P.F.D. and the third using benzene.
