摘要： A steam turbine includes a casing including a steam inlet and an exhaust, the casing enclosing operative structure of the steam turbine; a valve controlling introduction of a steam flow at a location of the steam turbine to impact an enthalpic condition of steam exiting the exhaust; and a controller controlling operation of the valve to attain a desired enthalpic condition of steam exiting the exhaust. Controlling operation of the valve allows for attainment of a desired enthalpic condition of the steam exiting the exhaust for use in another industrial process without having to modify the steam turbine structure.

摘要： A method of cooling a double flow steam turbine includes supplying steam flow to each nozzle of the sections of the turbine; reversing a portion of each steam flow to provide a reverse steam flow from an aft side to a forward side of each section. Each reverse steam flow is directed to an annular space between a rotor and a tub. The method further includes removing the reverse steam flows through a pipe, the pipe having a first end at the annular space at a first pressure and a second end at a second pressure that is lower than the first pressure. A double flow steam turbine, includes a pair of nozzles, each nozzle being provided at a section of the turbine; a rotor supporting buckets of the sections; a tub supporting the pair of nozzles; and a pipe extending from an annular space between the tub and the rotor. The pipe has a first end at the annular space and second end. A pressure at the first end of the pipe is greater than a pressure at the second end.

摘要： Disclosed herein is a method of minimizing losses in a multiple-last-stage bucket turbine. The method includes, determining an inlet flow available for the multiple-last-stage bucket turbine, and selecting multiple last-stage buckets from a set of pre-designed last-stage buckets. The multiple last-stage buckets having inlet flows different from one another that when combined match the inlet flow available with a lower total exhaust loss than from multiple same sized last-stage buckets from the set of pre-designed last-stage buckets.

摘要： A form assembly for forming a roof slab, an eave, and a peripheral beam in a monolithic structure is provided. The form assembly is detachably attached to upright columns of a housing frame structure and includes an eave formwork and a peripheral formwork. The eave formwork is mounted on the upright columns while the peripheral formwork is disposed between columns to be coupled to the eave formwork. The peripheral beam is formed between the eave and the roof slab and encloses a portion of top beams of the housing frame structure.

摘要： A front grille for a room air conditioning unit includes a planar front section, which includes an air inlet opening, an air outlet opening, and an opening configured to receive the unit's control panel when mounted on an air conditioning unit. The front section has a top wall, bottom wall, and left and right-hand side walls, each of which extend rearwardly of the front section and cooperate with one another to define a skirt element integrally formed with and extending rearwardly from the planar front section. An elongated recess is formed in the planar front section. One or more inserts, each of which is configured to be received in the recess in the front section, are provided. Each of the inserts has a distinguishing ornamental configuration thereon, which is different from the distinguishing ornamental configuration of the other inserts. Means are provided in the elongated recess and on each of the inserts for cooperating with one another to retain each of the inserts in the recess.

摘要： A steam turbine includes a shaft operatively connecting a first turbine section and a second turbine section. A packing assembly is positioned about the shaft. A first conduit is fluidly connected to the packing assembly. The first conduit is configured to introduce a flow of low temperature, low pressure steam to the packing assembly. A second conduit is also fluidly connected to the packing assembly downstream from the first turbine section and upstream from the first conduit. The second conduit receives a portion of the high temperature, high pressure steam passing into the packing assembly from the first turbine section. A valve is fluidly connected to the second conduit. The valve is configured to be selectively operated so as to allow the high temperature, high pressure steam to mix with the low pressure, low temperature steam in the second conduit.

摘要： An opposed flow high pressure-low pressure steam turbine balances thrust of the high pressure steam turbine with the thrust of the low pressure steam turbine allowing a reduction in size of thrust bearings. Higher stage reactions in both turbines may be incorporated since they are offset with the opposed flow, allowing a higher steam path efficiency. Opposed flow may be established through a cross-over pipe or utilizing a double high pressure shell.
