摘要： An apparatus estimates governor dynamics for a gas turbine engine used in a system. The apparatus is programmed to obtain a first set of parameters from a governing sub-system coupled to the system, obtain a second set of parameters from the governing sub-system, and generate governor dynamics estimates by utilizing the first and second sets of parameter outputs to solve a multiple objective optimization algorithm problem.

摘要： A gas-turbine engine combustion system has a combustor with a burner head having both pilot gas and pilot liquid-fuel injection arrangements, the pilot gas arrangement comprising an annular gallery communicating with a downstream face of the head and a deflecting arrangement adjacent the gallery for directing the pilot gas-fuel towards a longitudinal axis of the combustor and over a central part of the downstream face. The combustion system is designed so that, during both gas- and liquid-fuel operations, the flame front face is located close to the burner head and, during liquid-fuel operation, air is forced across the downstream face to cool the head. Advantageously, the cooling air is made to replace the pilot gas-fuel in the annular gallery, so that it is deflected, like the gas-fuel, and contacts the central part of the downstream face. The burner head also features main gas and liquid-fuel injection arrangements, these communicating with one or more passageways in a radial swirler attached to the head.

摘要： A variable length pre-mixer assembly comprises an upstream end for receiving compressed air from a compressor and a downstream end disposed in flow communication with a combustor. Pre-mixer assembly comprises an upstream forward clamp, a swirler assembly having a plurality of circumferentially spaced apart vanes disposed adjacent the upstream end for swirling compressed air channeled therethrough. An elongate centerbody has a first end joined to and extending through the swirler and a second end disposed downstream therefrom. A downstream fuel nozzle shroud has an outlet in flow communication with the combustor. Additionally, at least one removably disposed fuel nozzle spacer is alternatively disposed between a first position between the upstream forward clamp and the swirler assembly and a second position between the swirler assembly and the downstream fuel nozzle so as to change the relative position of the swirler assembly and alter the pre-mixer assemblies acoustical resonance characteristics.

摘要： A fuel flow control system to control fuel by regulating fuel pressure includes an inlet, an outlet, and a bypass passage. A variable orifice valve controls the flow of fuel between the inlet and the outlet in conjunction with a fixed orifice of an engine such that the relationship between pressure and fuel flow is substantially linear. A pressure-regulating valve accommodates pressure fluctuations in the system. A dual torque motor opens in proportion to the level of applied electrical current to control fuel pressure and thereby fuel flow.

摘要： A fuel flow control system for directing fuel within a combustion engine having a plurality of fuel introduction nozzles arranged in a plurality of operationally-distinct groups is disclosed. The system includes a plurality of pumping assemblies each corresponding to one of the nozzle groups. Each pumping assembly includes several fuel motivation elements, each in fluid communication with a fuel supply and a corresponding one of said nozzles. Drive elements, such as variable speed motors, are operatively associated with the pumping assemblies, and direct the motivation elements to transmit fuel to the nozzles. A control assembly independently controls the drive elements, so that fuel flow to each nozzle group is independently controllable. In one embodiment, the motivation elements in each pumping assembly are mechanically linked and operate as discrete groups of elements, thereby delivering uniform fuel flow to each nozzle within a given group of nozzles.

摘要： A gas turbine plant for limiting a sudden increase of load of the gas turbine, i.e., of the amount of fuel, and suppressing a stress of the turbine, or for maintaining a suitable fuel-air ratio is disclosed. The plant includes a controller comprising a section for calculating a governor signal for controlling the degree of opening of the fuel valve, based on a revolution speed of the gas turbine; and a section for calculating a load-limiting signal for following the governor signal, wherein when the governor signal decreases, the load-limiting signal is larger than it by a predetermined value, while when the governor signal increases, the increase rate of the load-limiting signal has a predetermined upper limit. The controller also comprises a limiting section, into which both signals are input, for limiting the upper value of the governor signal by using the load-limiting signal as an upper limit.
