Organic water conditioning agents may be added to an aqueous stream that is supplied to a steam generator, such as a heat recovery steam generator within a combined cycle power plant. These organic water conditioning agents may degrade to electrically-charged decomposition products that can interfere with cation conductivity measurements made on the aqueous stream. To allow deployment of the organic water conditioning agents, a sampling device can process aqueous samples to destroy interfering organic molecules, such as through heat or irradiation. Cation conductivity measurements can then be made on the aqueous sample after destroying and removing interfering organic species from the sample stream.

The present invention relates to a steam sample concentrator and conditioning (SSCC) system. The SSCC finds use in concentrating impurities carried in steam (e.g., used in power generation and other industrial processes) and facilitating steam analysis. A device for determining steam purity includes an isokinetic flow control device that maintain isokinetic flow of a steam sample stream through a nozzle, and a pump that prevents the steam sample stream from becoming superheated after the isokinetic flow control device. A contactor condenses the steam sample stream, and a separator that separates a condensate sample stream from a residual steam stream sample. A flowmeter measures a flowrate of the condensate sample stream and an analyzer is configured to measure impurities.

A steam turbine plant is provided with: a boiler; a fuel valve; a low-temperature steam generation source; a steam turbine; a main steam line that guides steam generated in the boiler to the steam turbine; a main steam adjustment valve that is provided to the main steam line; a low-temperature steam line that guides low-temperature steam from the low-temperature generation source to a position closer to the steam turbine-side than the main steam adjustment valve in the main steam line; a low-temperature steam valve provided to the low-temperature steam line; and a control device. During a stopping process of the steam turbine plant, the control device sends a command to close the fuel valve, and then sends a command to open the low-temperature steam valve.

An electric vehicle including the Rankine cycle in which a circulation system of working fluid is formed is proposed. The Rankine cycle includes a pump configured to circulate the working fluid along the circulation system, a heat source comprising a battery unit, a motor unit, and a solar panel unit to transmit thermal energy to the working fluid circulated by the pump, a power generating unit provided on a path of the circulation system to generate electric energy through the thermal energy of the working fluid passing through the heat source, and a radiator configured to perform a heat exchange process between the working fluid passing through the power generating unit and outside air. The Rankine cycle further includes a flow distributor to distribute the working fluid circulated by the pump to at least any one of the battery unit, the motor unit, and the solar panel unit.

An apparatus for reducing windage loss of steam turbines according to an embodiment of the present disclosure is to reduce or minimize damage to a blade caused by a rise in temperature at an outlet stage of a high-pressure turbine.

A device maintenance apparatus includes: a comparison target selector configured to select comparison targets of a device information of a device as a maintenance target; and a display configured to display a comparative information generated based on changes in the device information.

The present invention provides a method for open-loop controlling or closed-loop controlling and/or monitoring a device with an expansion engine which is supplied live steam of a working medium that is expanded to exhaust steam in the expansion engine comprising the steps: determining at least one physical parameter of the exhaust steam; determining at least one physical parameter of the live steam based on the determined at least one physical parameter of the exhaust steam; and open-loop controlling or closed-loop controlling and/or monitoring the device based on the at least one determined physical parameter of the live steam. A thermal power plant is also provided in which the method is realized.

A speed control system and a power load balance detector for a turbine is provided. The speed control system includes a speed wheel with a plurality of teeth. A timer stores a time stamp when each of the teeth passes by a speed probe. A first speed estimate is determined for overspeed protection, and a second speed estimate is determined for operational speed control. The power load balance detector trips or shuts down the turbine when an unbalance is above a first threshold and the speed of the turbine is above a second threshold.

A waste heat power generation device having: an evaporator that recovers waste heat energy to evaporate a working medium; an expansion turbine generator that generates electric power with the working medium being supplied from the evaporator; a condenser that condenses the working medium discharged from the expansion turbine generator; a pump that feeds the working medium condensed in the condenser toward the evaporator; a measuring device that measures the amount of power generated by the expansion turbine generator per unit time; and a control device that controls the driving of the pump based on the measurement result of the measuring device.

A system may include a gas turbine system. The gas turbine system may include a compressor, such that the gas turbine system may produce exhaust gas in an exhaust outlet when generating electricity. The system may also include a heat recovery steam generator (HRSG) that may use the exhaust gas to create steam, a manifold system configured to couple compressed air in the compressor to the exhaust outlet, and a controller configured to send a command to the manifold system to couple the compressed air to the exhaust outlet when a temperature of the exhaust gas is above a threshold.
