摘要： A method for controlling at least one operational parameter of a plant (1) having a combustion unit (3) can include estimating a status of at least one operational variable of the plant to identify an estimated value for the operational variable. For each operational variable, the estimated value for the operational variable can be compared with a measured value of the operational variable to determine an uncertainty value based on a difference in value between the measured value and the estimated value for the operational variable. A control signal can be generated based on a reference signal, the measured value, and the deviation value for sending to at least one element of the plant (1) for controlling a process of the plant (1).

摘要： This invention relates to a solar furnace. In particular, this invention relates to a solar furnace which is capable of raising the temperature of transfer medium. In use, the heated transfer medium can be used to generate electricity or put to other work, such as, for example, air conditioning, pasteurisation or desalination. In fact, for any situation that requires a source to generate work or power. The present invention describes a solar furnace for raising the temperature of a heat transfer medium, comprising a lens array for admitting incident thermal and solar energy onto a reflector portion and a pressure vessel. The reflector portion being generally shaped so as to concentrate said solar energy onto said pressure vessel. The pressure vessel having an inlet through which said heat transfer medium is injected and a central core which defines a continuous heat transfer path for said heat transfer medium to contact the surface of said pressure vessel and exit said pressure vessel at an outlet. The solar furnace described herein is totally self-contained, requiring no additional power and can be used at the most remote locations requiring very little maintenance.

摘要： A solar energy system can be controlled during periods of reduced insolation. For example, one or more environmental condition sensors can detect environmental properties indicating current or expected insolation levels and can generate at least one signal indicating a current or impending transient reduced-insolation event. The at least one signal can be received (for example, by a controller) from the sensors that indicates changes in insolation. Responsively to the at least one signal, characteristics of a current reduced insolation event or of an impending transient reduced-insolation event can be calculated. In response to the calculated characteristics, a quantity of available insolation can be calculated. An attemperation flow rate in the solar steam system can be controlled responsively to the calculated quantity of available insolation such that the temperature of steam entering the steam turbines is maintained within a predefined range.

摘要： A method is provided for controlling a short-term increase in power in a steam turbine including a fossil-fired steam generator having a flow path through which a flow medium flows. The method involves tapping off the flow medium from the flow path in a pressure stage and injecting it into the flow path on the flow-medium side upstream of a super heater heating surface of the respective pressure stage. A first characteristic value is used as a controlled variable for the amount of injected flow medium. The first characteristic value is characteristic of the deviation between the outlet temperature of a final super heater heating surface of the respective pressure stage on the flow medium side and a predetermined nominal temperature value. The nominal temperature value is reduced and, for the duration of the reduction in the nominal temperature value, the characteristic value is temporarily increased over-proportionately to the deviation.

摘要： In accordance with the present invention, there is provided a steam desuperheater which is integrated into a steam line. The steam desuperheater comprises a segment of steam pipe having one or more spring loaded spray nozzles attached thereto. Installed within the interior of the steam pipe of the desuperheater is a liner. The desuperheater is also provided with a steam flow measurement sub-assembly comprising a differential pressure transmitter including a pair of pressure gauges which are operatively connected to respective ones of a first pressure tapping which is formed in the steam pipe before the liner, and a second pressure tapping which is formed in the liner. The measurement of the differential pressure allows for a determination of steam flow through the desuperheater. In addition to the differential pressure transmitter outfitted onto the steam pipe, the steam flow measurement sub-assembly further preferably comprises pressure and temperature transmitters which are installed in the steam line upstream of the desuperheater for providing a density determination that is also required for the steam flow determination.

摘要： A waste heat steam generator for a gas and steam turbine power plant is provided. The generator has economizer, evaporator and superheater heating surfaces which form a flow path and through which a flow medium flows. An overflow line branches off from the flow path and leads to injection valves arranged downstream at a flow side of a superheater heating surface in the flow path. The overflow line permits a brief power increase of a downstream steam turbine without resulting in an excessive loss in efficiency of the steam process. The brief power increase is permitted independently of the type of waste heat steam generator. The branch location of the overflow line is arranged upstream of an evaporator heating surface at the flow medium side and downstream of an economizer heating surface.

摘要： A solar concentration plant which uses water/steam as a fluid, in any thermodynamic cycle for the exploitation of process heat, comprising an evaporation subsystem, where saturated steam is produced, a superheater subsystem through which the steam reaches the required conditions of pressure and temperature at the turbine inlet, and an attemperation system interconnected by a drum. A field of heliostats is pointed towards either of the subsystems (evaporator or superheater), in such a way to control both the pressure within the drum and the outlet temperature of the superheated steam.

摘要： A technique of controlling a steam generating boiler system includes using a rate of change of disturbance variables to control operation of a portion of the boiler system, and in particular, to control a temperature of output steam to a turbine. The technique uses a primary dynamic matrix control (DMC) block to control a field device that, at least in part, affects the output steam temperature. The primary DMC block uses the rate of change of a disturbance variable, a current output steam temperature, and an output steam temperature setpoint as inputs to generate a control signal. A derivative DMC block may be included to provide a boost signal based on the rate of change of the disturbance variable and/or other desired weighting. The boost signal is combined the control output of the primary DMC block to more quickly control the output steam temperature towards its desired level.
