Indirect Dry Cooling
Indirect Dry Cooling (IDCT) systems have been used for over 50 years for various applications in the power industry. Active for more than three decades in the indirect dry cooling market, SPX Dry Cooling has supplied the largest indirect system presently in operation in the world.
“We supplied the biggest Indirect Dry Cooling System powering a 4.1 GW plant in South Africa”
Steam flowing from the turbine is condensed by cold cooling water in either a surface condenser or in a jet condenser. The heated cooling water is then pumped to the heat exchangers arranged vertically around the perimeter of the natural-draft cooling tower.
“Few rotating parts (no fan) translates into low maintenance and high availability.”
The IDCT is a dry cooling system whose major benefits are:
- Elimination of additional water usage from the condensing power cycle.
- Flexibility in power plant site selection.
- No visible plume.
- Steam flowing from the turbine is condensed by cold cooling water in either a surface condenser or in a jet condenser.
