    摘要: In a method for operating a premix burner a water quantity is introduced into the burner and/or the reaction zone of the burner depending on at least one command variable formed from at least one measured value. The method in particular should also be used if a burner is operated in the actual sense dry, i.e., without water injection for nitrogen oxide injection, and the injected water quantity is less than 20% of the fuel quantity. The method can be used advantageously especially if a characteristic value derived from combustion pulsations or material temperatures is used as a command variable; such parameters are then kept below a permissible upper limit.

    摘要: A fuel strainer for use in a turbine that filters debris out of fuel feed lines of the turbine to prevent clogging of flame nozzles in the turbine. The strainer comprises an elongated straining member with a plurality of apertures therethrough. The sum of the cross-sectional areas of the apertures is significantly greater than the cross-sectional area of the fuel feed line, and each individual aperture is smaller than all of the fuel holes in the flame nozzles.

    摘要: A turbine device and a method of driving the turbine device are disclosed. The turbine device includes an admission channel, a turbine, and an injection channel. The turbine device may also include a regulator. The turbine is driven by injecting a primary fluid into the admission channel at a given velocity and simultaneously causing a secondary fluid to flow into the admission channel at a lower velocity. The primary fluid and the secondary fluid form a mixture in the admission channel, which flows toward the turbine. The velocity of the mixture is less than that of the primary fluid, while the mass flow of the mixture is approximately equal to the sum of the mass flows of the primary and secondary fluids. The regulator compares the rotational speed of the turbine to a target speed and regulates parameters associated with the turbine device if the rotational speed of the turbine and the target speed differ by more than a predetermined amount.

    摘要: A method of controlling a system is adapted to control flow to throat nozzle and vectoring nozzle actuators. The method comprises the steps of summing a plurality of signals representative of flow to the vectoring nozzle actuators with a signal representative of flow to the throat nozzle actuators to generate a total hydraulic flow signal. The total flow signal is then compared to a signal representative of total pump output to generate a reserve signal. Finally, a scaled rate limit signal is generated from the reserve signal and multiplied by predetermined ratio signals such that the ratio signals are limited by the difference between pump output and pump demand.

    摘要: Stall margin in a gas turbine compressor is controlled during acceleration by synthesizing the thermal enlargement of critical compressor stages to synthesize the temporary increase in blade-case clearance during acceleration. The change in clearance is used to produce an augmenting stator vane deflection signal which is summed with a steady state vane deflection signal to increase deflection during acceleration until the clearance returns to a nominal level when the expansion of the compressor parts stabilize.

    摘要: A differential throttle linkage control for controlling the flow of fuel to an engine receives a main input from the throttle lever, and a second input from a trim actuator motor through a movable portion of a programmed split cam. The throttle control algebraically sums the inputs to produce a single output operably connected to the fuel metering device of the engine. The programmed split cam modifies or neutralizes the effects of the trim input through selected ranges of the throttle lever input stroke.

    摘要: A combined cycle electric power plant includes gas and steam turbines and steam generators and a digital/analog control system. A gas turbine megawatt load control system is included in the control and it includes a feedforward load control which generates a fuel reference equal to the sum of a megawatt load demand and an idle speed fuel demand. The megawatt load control also includes a feedback load trimmer which provides minor corrective action on the operation of the feedforward load control. Gas turbine and combined cycle plant operation results in the generation of megawatts equal to an input demand value.
