摘要： A moisture separator which incorporates an inner cylinder disposed in coaxial relation with an exhaust pipe of a steam turbine utilizes the spiral secondary flow of a gas stream to remove liquids which are entrained therein. The moisture separator incorporates an inner cylinder which has one or more apertures through its wall. The inner cylinder is placed in coaxial relation with the exhaust pipe of a steam turbine with means for sealing the axial ends of an annular chamber formed between the cylinder and the exhaust pipe. Means are provided for dividing the annular chamber into a plurality of arcuate spaces and for removing liquid which collects within each of the arcuate spaces. The moisture separator utilizes the characteristic of gas streams which creates spiral secondary flows when forced to turn around a bend. The spiral flows cause liquid, which is entrained in a gas stream, to migrate to the inner surface of a pipe or cylinder and coalesce on the walls thereof. The moisture separator utilizes these characteristics of turning streams of gas in order to separate liquid from a moisture-laden gas stream.

摘要： A sequence of activating and deactivating arcuate nozzle chambers which together form a structure for admitting steam into a steam turbine and directing it through turbine blades. At least one small and one large nozzle chamber are cooperatively activated and deactivated to provide maximum turbine efficiency. After minimum admission operation has been achieved, a small nozzle chamber disposed arcuately adjacent the activated nozzle chambers is increasingly activated as load is increased. When the small nozzle chamber has been fully activated and load on the turbine increases further, the large nozzle chamber is increasingly activated with load. At a predetermined degree of activation of the larger nozzle chamber, the small nozzle chamber is increasingly deactivated as the large nozzle chamber is increasingly activated. When the large nozzle chamber has been completely activated and the load on the turbine increases further, the small nozzle chamber is again increasingly activated as the load increases. The most efficient turbine operation obtains when the small nozzle chamber is deactivated simultaneously with activation initiation of the large nozzle chamber. Suitable relative disposition of the nozzle chambers allows avoidance of double shock operation of the turbine blades when the previously described method is practiced.

摘要： A method and apparatus for converting high pressure, high temperature elastic fuild (such as steam) to elastic fluid having a desired relatively low pressure and low temperature. Relatively high pressure, high temperature steam supplied from any point (preferably from a steam drum or equivalent location) in a steam cycle is initially throttled from a high temperature and pressure to a relatively intermediate temperature and pressure. Such intermediate temperature and pressure steam is routed through the tube side of a heat exchanger and subsequently throttled to a relatively low temperature and pressure. The resulting low temperature and pressure steam is then separated into its liquid and vapor phase components wherein the vapor phase is transmitted through the shell side of the heat exchanger and absorbs heat from the intermediate pressure, and temperature steam. The relatively low pressure, low temperature steam exiting the heat exchanger has the desired thermodynamic state. The temperature of the steam exiting the heat exchanger may be regulated by adjusting the high to intermediate pressure throttling device and the pressure of the low pressure steam exiting the heat exchanger may be regulated by adjusting the intermediate to low pressure throttling device. Such temperature and pressure regulation permits maintenance of steam temperature and pressure leaving the heat exchanger for varying temperatures and pressures of the relatively high pressure, high temperature steam supply. Such temperature and pressure maintenance enables elastic fluid utilizing devices to operate efficiently and reliably for fluctuating pressures and temperatures of the supply source.

摘要： A nuclear steam turbine power plant system having an arrangement therein for extended fuel cycle operation. The power plant includes a turbine connected at its inlet to a source of motive fluid having a predetermined pressure associated therewith. The turbine has also connected thereto an extraction conduit which extracts steam from a predetermined location therein for use in an associated apparatus. A bypass conduit is provided between a point upstream of the inlet and the extraction conduit. A flow control device is provided within the bypass conduit and opens when the pressure of the motive steam supply drops beneath the predetermined pressure as a result of reactivity loss within the nuclear reactor. Opening of the bypass conduit provides flow to the associated apparatus and at the same time provides an increased flow orifice to maintain fluid flow rate at a predetermined level.

摘要： An improved cycle arrangement for a steam turbine system in which an auxiliary turbine drives a boiler feedwater pump. The turbine system includes a primary turbine driving an electric power generator. The primary turbine includes a high pressure section and a low pressure section. A boiler supplies steam to drive the primary and auxiliary turbines. A condenser recovers exhaust steam from the LP section and a plurality of feedwater heaters preheats condensate collected at the condenser and pumped back to the boiler. The system extracts steam from the HP turbine section for operating the auxiliary turbine. Extracted steam from the auxiliary turbine is isolated from the primary turbine by coupling the steam to a feedwater heater supplied solely from a corresponding extraction point of the auxiliary turbine. The exhaust steam from the auxiliary turbine is coupled directly to the condenser.

摘要： An ultrasonic cleaning apparatus and method is provided for a venturi flow nozzle which is mounted in a pipe having fluid flowing therethrough. The apparatus includes a plurality of ultrasonic transducers mounted in openings provided upstream of the venturi flow nozzle inlet. The transducers transmit ultrasonic waves directly into and thereby excite the fluid flowing through the venturi flow nozzle and create cavitation which cleans the nozzle. Additional transducers are preferably provided in the throat area of the venturi flow nozzle. In alternative embodiments, the transducers are mounted in high and low pressure taps associated with the venturi flow nozzle such that the transducers directly transmit ultrasonic waves into fluid flowing into the high and low pressure taps. The transducers may be mounted flush with the interior of the pipe or venturi flow nozzle, or the transducers may be mounted at a position spaced therefrom in the high and low pressure tap piping.

摘要： Power output of a steam turbine is increased by removal of at least one stage of blading in order to increase mass flow through the turbine. A flow guide or annular ring is installed in the space in the inner cylinder or blade ring surrounding the area from which the blading stage has been removed. The flow guide has a radially inner surface conforming generally to the surface configuration of the inner cylinder surrounding the turbine blades. The flow guide presents a relatively smooth, continuous surface to inlet steam flow so that flow separation and turbulence are reduced with a corresponding increase in efficiency.
