18-15: Closing The Loop – Which Method is Best for Your SystemClosed loop cooling systems deliver many benefits compared to traditional open loop systems, such as reduced fouling, less risk of fluid contamination, lower maintenance, and increased system reliability and uptime. Several methods are used to close the cooling loop, including the use of an open circuit cooling tower coupled with a plate & frame heat exchanger or the use of a closed circuit cooling tower. This study examines the total installed cost

It is practically as simple to use as the present Merkel Theory

The pulsation force is a combination of the aerodynamically generated pressure difference between the upstream and downstream side of the fan blade and the velocity (under) pressure generated by the surface of the blade tip

crossflow mechanical draft cooling tower was analyzed

The helper towers are now in commercial operation and recent field drift testing has validated the results of the R&D program

high strength of carbon rovings and innovative "damped" shaft design let fan blades to withstand the most severe duty points and limit blade deformation

One of the primary goals of EPRI's Heat Waste and Water Management Program is to improve the ability of the utility industry to predict and test the performance of power plant cooling systems

Hurricane Rita came ashore just east of Orange Texas on September 24

their components must be tested individually in test cells designed to that effect

Hexavalent chromate can be removed from cooling tower blowdown by either reducing it chemically or electro­chemical1y1 •2 to the trivalent form or by ion exchange and reuse in the system

and the cooling water was recycled through a sidestream softener was studied

continues to increase

The purpose of this paper is to provide a better understanding of axial
