    Abstract: The invention is related to a method for determining a fuel split setting value (101) utilisable for adjusting a fuel split setting for a combustion device (12), the fuel split setting defining a relation between main fuel (50) and pilot fuel (51). The invention is also directed to the correspond- ing control unit and the rotating machine for which this method is operated. The method comprises the steps of: retrieving a first information item correlated to a heating value of supplied main fuel (50); retrieving a second information item correlated to a combustor operating condition; retrieving at least one third information item representing stability of combustion in the combustion device (12); selecting a predefined pair of minimum and maximum boundary curves (100A, 100B;...) for the fuel split setting from a plurality of predefined pairs of boundary curves (100A, 100B;...) based on the first information item and the second information item, the minimum and maximum boundary curves (100A, 100B;...) defining a band of fuel split settings permitted for a range of second information item values; - determining the fuel split setting value (101) within the selected pair of minimum and maximum boundary curves (100A, 100B;...) based on the third information item, wherein the determined fuel split setting value (101) being utilisable for adjusting the fuel split setting for the combustion device (12).

    Abstract translation: 本发明涉及一种用于确定燃料分配设定值(101)的方法,所述燃料分配设定值(101)用于调节用于燃烧装置(12)的燃料分配设定,所述燃料分配设定定义主燃料(50)和先导燃料(51)之间的关系 )。 本发明还涉及相应的控制单元和操作该方法的旋转机器。 该方法包括以下步骤:检索与提供的主燃料(50)的发热值相关的第一信息项; 检索与燃烧器操作条件相关的第二信息项; 检索表示燃烧装置(12)中的燃烧稳定性的至少一个第三信息项; 基于第一信息项从多个预定义的边界曲线对(100A,100B; ...)中选择用于燃料分割设置的预定义的一对最小和最大边界曲线(100A,100B; ...) 第二信息项,限定对于第二信息项值的范围允许的燃料分割设置的频带的最小和最大边界曲线(100A,100B; ...) - 基于所述第三信息项确定所选择的一对最小和最大边界曲线(100A,100B; ...)内的燃料分配设定值(101),其中所确定的燃料分配设定值(101)可用于调整 用于燃烧装置(12)的燃料分配设置。
