Working Principle

Heat Transfer Process:

The hot fluid (such as coolant or condensate) from the steam turbine flows through the dry cooler’s tubes.

Ambient air is drawn over the tubes, allowing heat to be transferred from the fluid to the air.

Temperature Regulation:

The cooled fluid returns to the steam turbine system, maintaining optimal operating temperatures and improving efficiency.
