Title:
湿り圧縮を用いてガスタービンの動力を増大させる方法と装置
Document Type and Number:
Japanese Patent JP2005511947
Kind Code:
A
Abstract:
A gas turbine unit and method of operation thereof are disclosed. A very quick and easily controllable augmentation or reduction of shaft power produced by the gas turbine unit, in particular of large gas turbine units exhibiting a pressure ratio larger than 15 bar, is achieved by providing at least one liquid droplet injection device on the upstream side of the compressor for injecting liquid into the stream of intake air. The injection device allows the addition of liquid mass flow in the form of liquid droplets corresponding to the desired increase of shaft power. The amount of water mass flow corresponding to the desired increase or decrease of shaft power output is added or reduced in a substantially stepless manner immediately within a time interval determined by design characteristics of the injection device. Water mass flow is preferentially injected substantially across the entire cross-section of the intake air guide.
