    • A system for operating a combustor in a non-Premix mode of operation includes a combustor comprising a plurality of primary fuel nozzles annularly arranged around a center fuel nozzle, a fuel supply system that is fluidly coupled to the plurality of primary fuel nozzles and the center fuel nozzle, a steam injection system that is fluidly coupled to the fuel supply system and to at least one of the plurality of primary fuel nozzles or the center fuel nozzle and a controller. The controller is electronically coupled to the fuel supply system and the steam injection system. The controller is programmed to initiate the steam injection system to inject a flow of superheated steam into a flow of fuel from the fuel supply system upstream from at least one of the plurality of primary fuel nozzles or the center fuel nozzle during a non-Premix mode of operation of the combustor.
    • 用于在非预混合操作模式下操作燃烧器的系统包括:燃烧器,包括围绕中心燃料喷嘴环形排列的多个主要燃料喷嘴;燃料供应系统,其流体地联接到多个主要燃料喷嘴和中心 燃料喷嘴,流体耦合到燃料供应系统和多个主燃料喷嘴或中心燃料喷嘴中的至少一个的控制器的蒸汽喷射系统。 控制器电连接到燃料供应系统和蒸汽喷射系统。 控制器被编程为启动蒸汽喷射系统,以在非预混模式期间将过热蒸汽流喷射到来自多个主燃料喷嘴或中心燃料喷嘴中的至少一个上游的燃料供应系统的燃料流中 的燃烧器的操作。
