03-01: Why Every Air Cooled Steam Condenser Needs A Cooling Tower Sidestream SofteningThis technical paper will review the basic types of cooling systems utilized by utility power plants, and explain the reasons why it is advantageous to include a cooling tower in many dry cooling applications. A system where a cooling tower is used in conjunction with an air cooled steam condenser is called a parallel condensing system. This type of system utilizes three traditional types of heat exchangers: a cooling tower, an air cooled steam
