Abstract

1470527 Steam power plant; reciprocating steam compressors; rotary positive displacement compressors; steam pump valve gear W C LANG 8 Oct 1974 [7 Dec 1973] 56990/73 Headings F1F F1M F1N F1Q and F1T A steam power plant includes a boiler 1 having a first outlet 6 delivering high-pressure steam to a prime mover 4, e.g. a steam turbine, and a second outlet 16 delivering high-pressure steam in line 13 to first and second compressors 10, 11 adapted to compress the exhaust steam in line 12 from the turbine 4 back to substantially boiler pressure and to return the compressed steam back to the boiler in line 14. The exhaust steam in line 12 is compressed to an intermediate pressure in compressor 10 and then fed via line 15 to the second compressor 11. The first compressor 10 is a reciprocating-piston type, Fig. 2 (not shown), driven partially by the turbine and partially by the high-pressure steam in line 13. The steam is compressed in parallel-arranged cylinders (20) in which the pistons (31) are reciprocated both by a crank-shaft (22) driven by turbine 4 via a fluid coupling (24), and by high-pressure steam in line 13 fed to the back of the pistons via cam operated inlet and outlet valves (33), (34), the steam in line 12 to be compressed passing to and from the cylinder above the piston via pressure responsive inlet and outlet valves (30), (32). The second compressor 11 is of the eccentric rotor type, Fig. 3 (not shown), or of a sliding vane type, Fig. 4 (not shown), again driven partially by the turbine and partially by the high-pressure steam in line 13. In (Fig. 3) two cylindrical rotors (40) are mounted eccentrically on a shaft (42) in an associated casing (41), each casing having three radial vanes (44) defining chambers (A), (B), (C). The lowpressure steam from line 15 is compressed first in chamber (A) and further in chamber (B) before discharge to line 14. Chamber (C) is fed with high-pressure steam from line 13 to help drive the rotors. Again (Fig. 4), high-pressure steam is fed via one-way valves (67) to help drive the vaned rotor, and is mixed with the steam being compressed.
