Energy Study of A Gas-Fired Turbo-Generator
MetadataShow full item record
As far as energy utilization is concerned, the performance of a gas turbine-generator combination, depends on some key factors among which are; engine features, methods of utilizing heat energy associated with exhaust gases, fuel characteristics, variations in ambient conditions and variation of electric load. The present work is intended to evaluate specific heat consumption and specific fuel consumption of a 44 MW turbo-generator unit, at Ras Abu-Fontas Power and Water Station, in view of likely changes in ambient conditions of Qatar. The study also covers the effect of load changes on specific heat consumption and component efficiencies. The method used for performance evaluation is herein explained; necessary on-site measurements are identified and procedures used in the analysis are outlined. Validation of results is confirmed through comparison between calculated turbine inlet temperatures and measured values. Excellent agreement between these temperature values is shown to exist. Causes of energy loss are also discussed.
