89-09: Modification of the Induce Draft Cooling Tower at Cross GeneratingResearch Cottrell constructed the concrete induced draft cooling tower at Cross Generating Station in 1984. The initial performance test indicated a major tower deficiency. The subsequent performance tests I '85 '87 indicated a drastic degradation in performance. The tower was upgraded in April '88 during the scheduled plant outage of three weeks. The major modification included replacing the existing fill (approx. 180,000 cubic feet), nozzle

in essence

Determinations have been made at room temperature and at the temperature at which the samples were exposed

This paper traces the history of these fill designs while providing guidelines as to the proper fill selection

This is the continuation of the detailed independent evaluation of microbiological

corrosion coupons

A critical topic that continues to be discussed at CTI meetings is the need for water conservation across a broad spectrum of industries and municipal applications

Where to look for

plant health and safety considerations and availability of ancillary mechanical treatment systems

In a scenario of reducing the supply of water to industry

sometimes referred to as Propeller fans

Further power reductions may be realized as a result of lower cascade flow losses and improved airfoil insensitivity to roughness effects

Proper fan air flow testing
