Uch Power Station is a 586 MW combined cycle station (ISO rating) with a 3 x GE frame 9E gas turbine generators, 3 x Heat Recovery Steam Generators and a C7 Steam Turbine Generator situated in Baluchistan province of Pakistan. The turbine generators are hydrogen cooled and each generator has four 4 coolers. The cooler uses closed cooling water for the cooling of hydrogen.

In summer months, the closed cooling water temperature at generator cooler inlet remains approx. 43~44 °C and it causes the generator cold gas alarm to be enunciated whereas the design temperature is 36 °C with flow of 1215 gallons/min.

In view of above problem, could you please offer us some localized solution for our turbine generator.
