摘要： An on-line water wash system for a compressor having a bellmouth casing with a region of known high velocity inlet airflow and a number of rotating blades. The water wash system may include a number of water nozzles positioned within the bellmouth casing about the region of known high velocity inlet airflow and a stream of water droplets. The stream of water droplets is targeted by the water nozzles so as to avoid the bellmouth casing and the rotating blades.

摘要： A combustor for a gas turbine includes a main fuel injector for receiving compressor discharge air and mixing the air with fuel for flow to a downstream catalytic section. The main fuel injector includes an array of venturis each having an inlet, a throat and a diffuser. A main fuel supply plenum between forward and aft plates supplies fuel to secondary annular plenums having openings for supplying fuel into the inlets of the venturis upstream of the throats. The diffusers transition from a circular cross-section at the throat to multiple discrete angularly related side walls at the diffuser exits without substantial gaps therebetween. With this arrangement, uniform flow distribution of the fuel/air, velocity and temperature is provided at the catalyst inlet.

摘要： A wet compression system for a gas turbine compressor having a bellmouth that includes a plurality of nozzles for spraying a fine spray of liquid disposed within an aft section of the bellmouth. The aft section of the bellmouth may include a downstream half of the bellmouth, and the nozzles may be connected to a plurality of struts, each of the struts comprising a structural member that connects an inner diameter casing of the bellmouth to an outer diameter casing of the bellmouth. In some embodiments, the nozzles may be positioned on a leading edge of at least one of the struts and a minimum clearance of at least approximately 0.2 m may be maintained between the nozzles and the inner diameter casing of the bellmouth. In other embodiments, the nozzles may be positioned on a trailing edge of at least one of the struts and a minimum clearance of at least approximately 0.05 m may be maintained between the nozzles and the inner diameter casing of the bellmouth.

摘要翻译： 一种用于具有喇叭口的燃气涡轮压缩机的湿式压缩系统，所述喇叭口包括用于喷射布置在所述喇叭口的后部的液体的细微喷雾的多个喷嘴。 喇叭口的后部可以包括喇叭口的下游一半，并且喷嘴可以连接到多个支柱，每个支柱包括将喇叭口的内径壳体连接到外径壳体的结构构件 喇嘛 在一些实施例中，喷嘴可以位于至少一个支柱的前缘上，并且可以在喷嘴和喇叭口的内径壳之间保持至少约0.2m的最小间隙。 在其他实施例中，喷嘴可以定位在至少一个支柱的后缘上，并且可以在喷嘴和喇叭口的内径壳体之间保持至少约0.05μm的最小间隙。

摘要： A combustor for a gas turbine includes a main fuel injector for receiving compressor discharge air and mixing the air with fuel for flow to a downstream catalytic section. The main fuel injector includes an array of venturis each having an inlet, a throat and a diffuser. A main fuel supply plenum between forward and aft plates supplies fuel to secondary annular plenums having openings for supplying fuel into the inlets of the venturis upstream of the throats. Each diffuser transitions from a circular cross-section at the throat to multiple discrete angularly related side walls at the diffuser exit. Gaps between circumferentially and radially spaced diffusers at their exits are eliminated. With this arrangement, uniform flow distribution of the fuel/air, velocity and temperature is provided at the catalyst inlet.
