Abstract

The invention provides an adjustable inlet guide blade of a gas compressor of a gas turbine. The adjustable inlet guide blade is characterized by comprising a rotating shaft, a middle circular disc and a blade body, wherein a sealing groove is formed in the circumferential face of the circular disc, and an O-shaped ring is arranged in the sealing groove; one end of the rotating shaft is connected with the middle circular disc, a connector is arranged at the other end of the rotating shaft, a fixing hole is formed in the connector, the fixing hole is formed in the axial direction of the rotating shaft, and a pin connecting hole is formed in the circumferential face of the connector and penetrates through the fixing hole; and one end of each blade body is fixedly connected with the side, away from the rotating shaft, of the circular disc, the sectional area of the blade body is gradually reduced from the blade root to the blade top, and the section comprises the following parameters of section blade height L, chord length b, mounting angle beta, maximum thickness T, leading edge thickness t1, trailing edge thickness t2, inlet mounting angle beta1 and outlet mounting angle beta2. According to the adjustable inlet guide blade of the gas compressor of the gas turbine, the safety and reliability of the gas compressor of the gas turbine can be improved, and the operation efficiency of the gas turbine is improved.

Description

technical field [0001] The invention relates to the technical field of gas turbine working fluid flow control, in particular to an adjustable inlet guide vane of a gas turbine compressor. Background technique [0002] During the operation of the gas turbine, there are various operating conditions such as increasing speed, increasing load, full load and shutting down. It is necessary to adjust the angle of the adjustable inlet guide vane (IGV) to adjust the intake flow and airflow angle to match various operating conditions. needs, so as to achieve the purpose of protecting the safe operation of the unit and improving the operating efficiency. [0003] For example, document CN111622843A discloses a gas turbine operating method and a gas turbine, which is composed of a compressor, a combustor, a turbine, a generator, and a control device. According to the metal temperature of the compressor as the state parameter and the vane vibration stress value as an index, the opening de...
