Dry Coolers For Gas Turbine Power Plants

Dry Coolers for Gas Turbine Power Plants

A dry cooler is a common type of heat sink used in power plant applications to reduce the heat generated by power generation equipment (e.g. gas turbines, steam turbines, etc.).

The following is an example of a dry cooler in a power plant application.

Project Name: Gas Turbine Power Plant Dry Cooler Upgrade Project

Background: The power plant is located in a country where, due to increased environmental regulations and energy efficiency requirements, the plant decided to upgrade the existing wet cooling system to a dry cooler system in order to reduce the use of water and increase the efficiency of power generation.

Dry Coole Design Parameters:
Gas turbine power: 200 MW
Cooling airflow: 200,000 m³/h
Design temperature drop: 15°C
Number of turbines: 10
Type of dry cooler: Vertical dry cooler
Fan type: EC fan with inverter control
Floor space: 2000 square metres

Project Feedback: The dry cooler system has performed very well in practice. Compared to traditional wet cooling systems, the dry cooler system reduces dependence on water resources, lowers maintenance costs, and improves the reliability of the plant. The dry cooler system is also more resilient to both dry and humid climatic conditions, reducing system fluctuations due to climate change.
