Abstract: A method for operating a gas turbine power plant, and a gas turbine power plant in which fresh air is delivered to a compressor inlet and is accelerated in the compressor inlet and a recirculated first exhaust gas substream is delivered into a region of the compressor inlet in which the fresh air is accelerated to an extent such that the difference between total pressure and static pressure in the fresh air is greater than or equal to a pressure difference which is required in order to suck a target mass flow of the recirculated first exhaust gas substream into the compressor inlet.

Abstract: What is described is a method for operating a gas turbine power plant, in which fresh air is delivered to a compressor inlet and is accelerated in the compressor inlet and a recirculated first exhaust gas substream is delivered into a region of the compressor inlet in which the fresh air is accelerated to an extent such that the difference between total pressure and static pressure in the fresh air is greater than or equal to a pressure difference which is required in order to suck a target mass flow of the recirculated first exhaust gas substream into the compressor inlet. What is described, further, is a gas turbine power plant with a gas turbine, the compressor inlet of which is divided into two sectors which the flow duct of the compressor adjoins, a feeder for fresh air being connected to the first sector and a recirculation line for recirculating the first exhaust gas substream being connected to the second sector, and the second sector reaching so close to the compressor that, when the gas turbine is in operation, the static pressure at the outlet of the second sector is so low that the difference between total pressure and static pressure is greater than or equal to a pressure difference which is required in order to suck a target mass flow of the recirculated first exhaust gas substream into the compressor inlet.

Abstract translation: 所描述的是一种用于操作燃气轮机发电厂的方法，其中新鲜空气被输送到压缩机入口并在压缩机入口中被加速，并且再循环的第一废气子流被输送到压缩机入口的区域，其中 新鲜空气被加速到使得新鲜空气中的总压力与静压之差大于或等于为了将再循环的第一排气气流的目标质量流吸入到空气中所需的压力差的程度 压缩机入口。 此外，还描述了一种具有燃气轮机的燃气轮机发电厂，其压缩机入口被分成压缩机的流动管道邻接的两个扇区，用于新鲜空气的进料器连接到第一扇区，再循环 用于再循环连接到第二扇区的第一废气子流线，并且第二扇区达到如此靠近压缩机，当燃气轮机运行时，第二扇区出口处的静压力如此之低，使得 总压力和静压之间的差异大于或等于为了将再循环的第一排气气流的目标质量流吸入压缩机入口所需的压力差。
