    摘要: In order to regulate fuel flow to the combustor (36) of the combustion turbine engine (10) having a primary combustion zone (64) and at least one further combustion zone, the temperature of the inlet and outlet of the combustor (36) are determined, as are first and second values representing first and second properties, with the first property being one of: the total enthalpy rise in the combustor (36), the equivalence ratio of the combustor (36), the fuel/air ratio of said combustor (36), the fuel flow through the combustor, and the second property being one of: the enthalpy rise in the primary zone (64), the equivalence ratio of said primary zone (64), the fuel/air ratio of the primary zone (64); the temperature rise across the primary zone (64), or the fuel flow through the primary zone (64). The second property is determined from the first value and the current value of the ratio of the fuel to the primary zone (64) to the total fuel to the combustor (36). The temperature of the outlet of the primary zone (64) is thus determined from the inlet temperature and the second value, are compared with a predetermined temperature to generate a control signal dependent on the difference. The fuel to the primary zone (64) is then varied, to vary the control signal to reduce the difference. This use of ratios eliminates the need for a gas chromatograph, flow ratios and humidity sensors to determine the properties of the gas.

    摘要: A method of compressing a gas, which uses a compressor train having a plurality of discrete portions and including at least an upstream portion, a mid-stream portion and a downstream portion arranged successively in flow series. The method includes: (i) performing a first compression step by directing a flow of said gas into the upstream compressor portion and driving the upstream compressor portion to compress the gas; (ii) performing a second compression step by directing the compressed flow from the upstream compressor portion into the mid-stream compressor portion and driving the mid-stream compressor portion to further compress the gas; and (iii) performing a third compression step by directing the compressed flow from the mid-stream compressor portion into the downstream compressor portion and driving the downstream compressor portion to further compress the gas.

    摘要: An industrial system for compressing a waste gas product, such as CO2, including a compressor train having an upstream rotor portion and a downstream rotor portion arranged in flow series with said upstream portion. Each rotor portion includes one or more compressor stages and said downstream portion is arranged to rotate at a variable relative speed to that of the upstream rotor portion. Sensing equipment for the compressor train is arranged to determine one or more flow conditions and a controller is arranged to receive data indicative of said one or more sensed flow conditions. The controller is arranged to set the rotational speed of the upstream rotor portion based upon the pressure or flow rate of gas upstream of said compressor train and to set operational parameters for said downstream portion so as to maintain a desired surge margin for said upstream rotor portion.

    摘要: A phased array antenna that employs a switched least means squared architecture comprises plurality of receiving elements each having a respective weighting unit associated therewith, a summation unit, a processor, a plurality of sampling devise and a switching unit contains a switch arm having a contact at its free and, an ADC and a plurality of switch contacts corresponding to the ends of channels connected to the respective sampling devices. Each of a plurality of receiving elements is ampled by a respective sampling device prior to an incoming signal subjected to complex weighting by respective weighting units. Each of the signals sampled by the sampling device passes along respective channels to the switching unit. Thus, by switching between the contacts it is possible to vary which of the receiving elements is sampled. The processor calculates new complex weighting coefficients to be applied to the incoming signals by the weighting units using the sampled incoming signals in order to minimize a difference between an output from the summation unit y and a training signal d.
