Biomass is identified as one of the major renewable energy sources for electrical power generation. Heavy duty gas turbine engines are preferred for clean and efficient power generation. An extensive literature survey reveals that the governor droop setting of the heavy duty gas turbines varies from 2 percentage to 10 percentage. But it needs to be optimized for analyzing the dynamic response o...

There is a strong incentive for gas turbine operators to minimize and control performance degradation, as this directly affects profitability. The area of gas turbine recoverable and non-recoverable performance degradation will be comprehensively treated in this tutorial. Deterioration mechanisms including compressor and turbine fouling, erosion, increased clearances, and seal distress will be ...

A gas turbine inlet filtration system is important for successful operation. The filtration system minimizes the occurrence of foreign object damage, erosion, fouling, and corrosion. The selection of the inlet filtration system is a challenging process which involved choosing multiple filtration stages based on the desired performance of the gas turbine and the local operating environment. This...

Power enhancement technologies for gas turbines such as inlet fogging, interstage water injection, saturation cooling, inlet chillers, and combustor injection are being used by end users without evaluating the potentially negative effects these devices may have on the operational integrity of the gas turbine. Specifically, the effect of these add-on devices, off-design operating conditions, non...

In this paper combined Brayton–Rankine cycle was mathematically simulated. In the Matlab program package an adequate numerical procedure has been developed to determine the maximum thermal efficiency of the combined cycle limited by the temperature of exhaust gases at the entrance of the gas turbine and the temperature of the condensation of water vapour in the steam condenser. Furthermore, add...

R & D Journal of the South African Institution of Mechanical Engineering 2014, 30, 55-67 http://www.saimeche.org.za (open access) © SAIMechE All rights reserved. 55 A variety of working fluid thermodynamic property models are applied in gas turbine performance simulations, potentially giving rise to significant discrepancies in performance prediction. Literature indicates that little attention ...

Gas turbines play an important role in supplying power for the country especially in peak electricity load. The main disadvantages are the turbines, they produce large changes are a result of climate change. However, in times of peak electricity grid and at the same time warm months, can produce gas turbines under the effect of ambient temperature, the amount of reduced considerably. The method...

The combined cycle gas turbine integrates the Brayton cycle as topping cycle and the steam turbine Rankine cycle as bottoming cycle in order to achieve higher thermal efficiency and proper utilization of energy by minimizing the energy loss to a minimum. In this work, the effect of various operating parameters such as maximum temperature and pressure of Rankine cycle, turbine inlet temperature ...
