    • A gas turbine engine (10) comprises a second compressor (14), a first compressor (16), a heat exchanger (18), a combustor (20), a first turbine (22), a second turbine (24) and a third turbine (26) arranged in flow series. The first turbine (22) is arranged to drive the first compressor (16). The second turbine (24) is arranged to drive the second compressor (14). There are means to inject liquid into the gas turbine engine (10). The means to inject liquid is arranged to inject liquid upstream (46) of the second compressor (14), within (48) the second compressor (14), between (50) the second compressor (14) and the first compressor (16), within (52) the first compressor (16), between (54) the first compressor (16) and the heat exchanger (18) or within (56) the combustor (20) to boost the power of the gas turbine engine (10). The means to inject liquid is arranged to inject liquid between (70) the combustor (20) and the first turbine (22), within (68) the first turbine (22), between (66) the first turbine (22) and the second turbine (24), within (64) the second turbine (24), between (62) the second turbine (24) and the third turbine (26), within (60) the third turbine (26) or between (72) the third turbine (26) and the heat exchanger (18) to reduce the power of the gas turbine engine (10).

    • 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.
    • 为了调节到具有主燃烧区(64)和至少一个另外的燃烧区的燃气涡轮发动机(10)的燃烧器(36)的燃料流,燃烧器(36)的入口和出口的温度为 确定,以及表示第一和第二属性的第一和第二值,第一属性是以下之一:燃烧器(36)中的总焓升高,燃烧器(36)的当量比,所述燃烧器(36)的燃料/空气比 燃烧器(36),燃料通过燃烧器的流动,第二特性是以下之一:初级区域(64)中的焓升高,所述初级区域(64)的当量比,初级区域的燃料/空气比 区(64); 主区域(64)的温度上升,或通过主区域(64)的燃料流。 第二特性根据燃料与主要区域(64)与燃烧器(36)的总燃料的比率的第一值和当前值确定。 因此,从入口温度和第二值确定主区域(64)的出口温度与预定温度进行比较,以产生取决于差值的控制信号。 然后改变到主区域(64)的燃料以改变控制信号以减小差异。 这种比例的使用消除了气相色谱仪,流量比和湿度传感器的需要,以确定气体的性质。
