Air Cooled Condensers:
Application and Innovative Designs for
Today's Power Plants
2
The utilization of Air Cooled Condensers inpower plants has increased exponentiallyaround the world over the last 15 years.Previously, the use of Dry Cooling for powerplant applications was typically used when therewas a limited supply of available water for thesteam cycle condensation. Currently, Air CooledCondensers are justified based on new plantevaluation factors including the availability andactual cost of water, environmental impact (drift,plume, blow down, water treatment chemicals,Legionella risk, etc.) flexibility in site selection,and a reduced time period for securing air andwater environmental permits.
SPX, a world leader in cooling technologiesfor power plants, will review the current trends intoday’s Dry Cooling power market, and alsodescribe in detail three unique state-of-the-artproblem solving Air Cooled Condenser (ACC)designs for both small and large power plants.
Abstract
The innovative ACC designs will include:
An advanced design and project executionplan for a Dry Cooled 500 MW Combined CyclePower Plant (CCPP). This project consisted of anew modularisation concept for an Air CooledCondenser barged over 500 km and erected inNew York City, saving both millions of dollars insite erection costs and many months of siteerection time compared to traditional methods ofACC execution. This project description willcover the key challenges, the innovativesolutions and the various steps of the project.Details of the different phases of constructionwill illustrate today’s largest and most advancedmodularisation and preassembly of an AirCooled Condenser ever executed worldwide.
A new unique modularised ACC designconcept—Hexacool ®—optimised for smallbiomass incineration plants. This revolutionaryconcept provides many advantages includinglow noise emissions, lower material costs and aquicker / lower cost site erection.

REASONS
• Environmental regulations for water saving
• Environmental regulations, limiting the temperature increase in
rivers and seaside
• Local regulations favoring equipment without a plume discharge
• Flexibility in the selection of the power plant site
• Life expectancy exceeding power plant life
• Shorter lead-time for power plants permits
Dry Cooling for Power PlantsA Rapidly Growing Market
The valuation of these advantages can offset the additional
Capital Cost of Dry compared to Wet Cooling
