Possible performance enhancement of small gas turbine power plants through the application of thermoacoustic systems is examined. The thermoacoustic subsystem is powered only by the waste heat of the gas turbine. Two different gas turbine configurations are considered: a Thermoacoustic refrigerator assisted gas turbine (TRG) and a Combined thermoacoustic heat pump and refrigeration assisted gas ...

In this paper, the first and second laws of thermodynamics have been utilised to evaluate the performance of intercooled reheat regenerative gas turbine cogeneration plant. The effects of overall pressure ratio, cycle temperature ratio, pressure losses, and process steam pressure on energetic and exergetic efficiencies have been investigated. The results indicate that most of the exergy ...

Problem Two large gas turbines (approximately 25m x 12m x 10m) were installed in an industrial area nearby an office building. The gas turbines generate a tonal noise component at around 2700Hz caused by the inlet channel blades pass frequency. This tone imposes a more stringent noise requirement on the supplier, forcing noise reducing actions being made on the turbine. Measurements and noise ...

In this study, the effects of gas turbine inlet air-cooling by evaporative technique on work output and thermal end exergy efficiency were analysed. These analyses are performed with the use of per unit volumetric flow, which is fixed regardless of atmospheric air conditions. In addition, a simple and effective model is developed for the economic analysis of evaporative cooling. As a case study, ...

The performance of a 1000 kW gas-turbine cogeneration system was evaluated in terms of performance measures, such as net power, exergy efficiency of the system, and the unit costs of electricity and steam. The efficiencies of some components that have a significant affect on the performance were taken as physical variables. Sensitivity was evaluated by introducing parameters, defined as the ratio ...

A backward Lagrangian Monte Carlo modelling is proposed to calculate by post–processing the PDF of the thermo–chemical parameters of complex turbulent reactive flows simulated with a simple turbulent combustion model. PDF's of minor species such as pollutant species (NOx, soot, unburnt hydrocarbons...) can be easily obtained as long as these species have no significant influence on the main ...

In the present work, gas turbine cycles are modified with steam injection between the combustion chamber exit and the gas turbine inlet. Heat recovery steam generators, utilising the exhaust gases, provide these cycles with the injected steam at saturated vapour. The irreversibility of the different composing units of the cycles and the variation of gas properties owing to steam injection as well ...

Unexpected failures, loss of production, higher maintenance costs and down time associated with the failures of equipment are major problems in any plant. Adopting the risk-based maintenance (RBM) approach helps in designing an alternative strategy to minimise the loss resulting from these breakdowns or failures. The methodology consists of four modules: system definition, risk assessment, risk ...
