Efficient gas turbine generator sets
Hilbert vertical vibration of the rotor when the spectrum shown in Figure 4, vibration response in more than 2 high-end components disappear. Rotor speed in the sub-critical operation, so that the crack normal and the angle between the change in balance, because the rotor rubbing coupling vibration, easily concealed crack and Rubs information, is not conducive to timely detection of the failure. 6 Conclusion In this paper, local wave frequency analysis on the crack and rubbing rotor vibration response of the coupled analysis shows that when the Hilbert spectrum can reflect the response of multiple nonlinear time-frequency characteristics of the rotor, not only clearly shows that the response of the various frequency components, but also accurately describes the time variation of instantaneous frequency components, reflecting the size of each component of the energy distribution over time, so it can also be used to monitor the development of early failure characteristics of the actual rotor system fault monitoring and diagnosis.

Efficient gas turbine generator sets (Drainage source editing), according to ((GasTurbineworla)> 20o2 number reported in March-April, the Netherlands ScheldeHeronBV developed H-1 gas turbine. Simplified water to air intercooler to reduce the gas turbine compressor between sections of the working fluid temperature, and increases the mass flow rate through the compressor and the compressor to reduce power consumption. made of one of the base load heat exchanger to provide 43% of electricity production thermal efficiency. in two separate parts of the combustion chamber operation, in the upstream combustion chamber ignite the fuel-driven gas generator turbine, the hot gas leaving the turbine, power turbine before entering the combustion in the second part of the re-heat, combined combustion-driven power turbine order. HeronH-1 Gas Turbine is a two-axis back to the middle of cold thermal gas turbine. It is characterized by the gas generator turbine driven by a single two-stage axial flow centrifugal compressor parts. runoff on the uniaxial free power turbine driven by reduction gear box generator. H-1 type gas turbine generator sets the output power of 1407kW 42.9% thermal efficiency, fuel consumption 0.086ks / s, the rotor inlet temperature is 861oC, pressure ratio of 8.78:1, the inlet air flow To 5.15ks / s, the exhaust temperature of 620oC.
