الملخص

The cooling system of gas turbines is regarded as an important andbasic system that affects the efficiency of the gas turbines units. The gasturbine units 5, 6 and 7 at Garri-2 Power Station are examples of the gasturbine units that are greatly affected by the cooling system.Since their installation in 2001, these units suffered from lowefficiency of the system used (fin-fan air cooler), as it depends on theambient temperature in the process of heat exchange. This leads to therise of the temperature of the lube oil, used in bearings lubrication, duringthe period from March to September. The temperature of the lube oil mayreach 79°C during this period which causes a drop in the efficiency andautomatic stop of the gas turbine unit.The objective of this research is to investigate the feasibility ofimproving the efficiency of the cooling system in gas turbine units 5, 6and 7 by utilization of the surplus cooling capacity of the station coolingtowers.To meet the objective of this research, calculations were carried out todetermine the surplus cooling capacity. The calculations showed thatthere was a surplus cooling that could be used in cooling gas turbineunits. The necessary calculations were made to select a heat exchanger tobe used in cooling gas turbine units. Also an economic study wasconducted to determine the feasibility of this modification.The study showed that the cooling system of the gas turbine unitswould become more efficient by incorporating a heat exchanger in thesystem to utilize the surplus cooling capacity of the cooling towers. Thecost this modification in could be recovered in not more than 17 monthswith an annual saving to equivalent 285845.76 SDG.
