    摘要: A method and a system for limiting steam flow entering a steam turbine are provided. The method and system may intentionally unbalance the steam flow apportioned between sections of the steam turbine. The steam turbine comprises at least: a first section, a second section, and a rotor disposed within each section. The method may receive a speed/load command, or the like, which provides reference strokes for a first valve, associated with the first section; and a second valve, associated with the second section. The method may also determine an operational parameter that may limit the reference strokes relative to the speed/load command. The operational parameter may determine the allowable steam flow for each section of steam turbine, independent of the speed/load command.

    摘要: In a dual-source organic Rankine cycle (DORC), the condensed and slightly sub-cooled working fluid at near ambient temperature (˜300 K) and at low-side pressure (0.1 to 0.7 MPa) is (1) pumped to high-side pressure (0.5-5 MPa), (2) pre-heated in a low-temperature (LT) recuperator, (3) boiled using a low-grade heat source, (4) super-heated in a high-temperature (HT) recuperator to a temperature close to the expander turbine exhaust temperature using this exhaust vapor enthalpy, (5) further super-heated to the turbine inlet temperature (TIT) using a mid-grade heat source, (6) expanded through a turbine expander to the low-side pressure, (7) cooled through the HT recuperator, (8) cooled through the LT recuperator, (9) mostly liquefied and slightly subcooled in a condenser, and (10) the condensed portion is returned to the pump to repeat this cycle.

    摘要: A method and apparatus are disclosed for alleviating the problem of windage heating when flow, in a turbine running at full speed, no load, decreases greatly at the exhaust of the high pressure sections of the turbine. Valves connecting the different pressure levels of a heat recovery steam generator to the input of the turbine are adjusted to mix steam coming from the different pressure levels to create desired steam conditions at the inlet and the exhaust output of the turbine that allow the use of existing steam path hardware and thereby reduce the cost of such piping. In an alternative embodiment for a single pressure HRSG, high pressure saturated steam is extracted from the HSRG evaporator and then flashed into superheated steam when passing thru a control valve, that is then used to create the desired steam conditions at the inlet and the exhaust output of the turbine.

    摘要: A method for repairing power plant boilers provides for a water mist insertion into the furnace to provide for more rapid cooling, which allows personnel to enter into the furnace to conduct repairs in a shorter time. Water mist is provided by air-water mixing atomizing sprayers that are inserted into the boiler. Existing power plant oil igniter lighters may be switched from oil to water to provide the air-water mixed atomized mist.

    摘要: The present invention relates to a method for preventing the deposition of contaminants in steam systems. In a method of this type, deposits are prevented in a simple and economic manner by metering an additive into the steam, which additive adheres to the steam-side surface of the steam system and has the effect of repelling moisture and contaminants.

    摘要: A process for removing hydrogen sulfide from geothermal steam and from vent streams, or concentrated portions produced by a hydrogen sulfide separation process, includes the steps of introducing an oxygen-containing gas, such as air into the steam, or vent stream, and thereafter contacting the steam and oxygen-containing gas in a contacting stage with iron oxide supported by a carrier resistant to deterioration. The steam having a temperature of at least 250.degree. F. is mixed with oxygen to provide a molar ratio of oxygen-to-hydrogen sulfide ratio of less than about 10. During the contacting stage the pressure of the steam and oxygen-containing gas is maintained at a pressure sufficient to enable removal of a majority of the hydrogen sulfide from the steam and oxygen-containing gas.
