Abstract

1,163,541. Steam turbine plant; injectors. ENGLISH ELECTRIC CO. Ltd. May 19, 1967 [May 20, 1966], No.22715/66. Headings F1E and F1T. In a steam turbine plant having a boiler feed pump 30 driven by an auxiliary turbine 16, the auxiliary turbine is supplied with steam from an intermediate point 20 of the main turbine 11, 32 through an ejector 33 arranged to be supplied with steam from a second point upstream of the intermediate point and means is provided for varying the mixing of steam in the ejector. In operation with the main turbine on full load, a throttle valve 39 at the outlet of the ejector is partly closed and the needle valve 42 of the ejector is closed. As the main turbine load is reduced a pressure responsive device 47, through an electric or fluidpressure operated system 48, causes throttle valve 39 to open increasing the pressure of the steam supplied to the auxiliary turbine 16. When the valve 39 is fully open the device 47 begins to operate a servo-mechanism 49 actuating the needle valve 42 so that live steam from the plant boiler is fed through the ejector nozzle. To prevent excessively high temperatures in the ejector 33 the live steam may be desuperheated. The throttle valve 39 may be mounted at the inlet 34 to the ejector 33. In a further embodiment, Fig. 5 (not shown), a by-pass (51) is provided direct from the live steam supply (10) to the auxiliary turbine (16) and the by-pass contains a valve (52) opened by the pressure responsive device (47) at very low main turbine loads. The device (47) may be arranged to close the needle valve (42) and the throttle valve (39) immediately the by-pass valve (52) opens. In another embodiment, Fig. 6 (not shown), live steam is supplied to the ejector nozzle through a desuperheater (52) having a spray-control valve (53) governed by a temperature controller (54) linked to the desuperheater outlet. The supply pipe (35) from the main turbine (11, 32) is provided with a throttle valve (55) operated in conjunction with the needle valve (42) and a by-pass (56) direct to the auxiliary compressor (16) containing a non- return valve (57). The by-pass non-return valve (57) when open operates a switch to close the needle valve (42). The line supplying steam to the ejector nozzle may be provided with a throttle valve to control operation of the ejector.
