IMPROVED OPERATION METHOD OF COOLER FOR GAS TURBINE AND SUPPORT DEVICE

摘要

PURPOSE: A method for cooling a gas turbine and a support device is provided to smoothly and continuously operate the gas turbine and the support device by changing a supply line to prevent an area which does not satisfy the temperature standard of the gas turbine from being expanding. CONSTITUTION: A method for cooling a gas turbine and support device is provided to cool a gas turbine and a support device by including upper and lower cooling devices. The upper and lower cooling devices independently operate in a normal operating state. When the lower cooling device does not satisfy a temperature standard, cold air supplied through the upper cooling device flows into the lower cooling device through a fluid path conversion unit. The fluid path conversion unit is an opening and closing valve. The fluid path conversion unit is an automatic or manual damper device.
