估计具有排气再循环的燃气涡轮的燃烧当量比的系统和方法
摘要：
一种系统包括排气再循环(EGR)燃气涡轮系统，该EGR燃气涡轮系统包括被配置为接收并燃烧燃料和氧化剂的燃烧器以及由来自燃烧器的燃烧产物驱动的涡轮以及由来自燃烧器的燃烧产物驱动的涡轮。EGR燃气涡轮系统进一步包括流体地耦连到涡轮和燃烧器的排气再循环部，其中该排气再循环部被配置为吸入来自涡轮的排气并且将排气的至少一部分再循环到燃烧器作为稀释剂。该EGR燃气涡轮系统还包括控制系统，该控制系统包括一个或多个处理器，所述处理器被配置为接收表示排气的排气流量成分的第一信号并且接收表示稀释剂的稀释剂流量成分的第二信号。
摘要（英）：

A system includes an exhaust gas recirculation (EGR) gas turbine system which includes a combustor configured to receive and combust a fuel with an oxidant and a turbine driven by combustion productsfrom the combustor and a turbine driven by combustion products from the combustor. The EGR gas turbine system further includes an exhaust gas recirculation section fluidly coupled to the turbine and to the combustor, wherein the exhaust gas recirculation section is configured to intake an exhaust gas from the turbine and to recirculate at least a portion of the exhaust gas to the combustor as a diluent. The EGR gas turbine system additionally includes a control system, comprising one or more processors configured to receive a first signal representative of an exhaust flow composition of the exhaust gas and to receive a second signal representative of a diluent flow composition of the diluent.
