TP24-13 An Overview of Mechanical Loads on Cooling Fans in Different ApplicationsCooling fans used in cooling towers (CTs), air cooled condensers (ACCs) and air cooled heat exchangers (ACHEs) are typically produced in a diameter range of 1. 524 m (60 inches) to 12. 192 m (40 feet). During operation, these fans experience a variety of mechanical loads influenced by the aerodynamic duty, rotational speed and inlet air flow conditions.

Description of the fouling factor changes observed during winter and summer chlorination outages and are compared to fouling factors measured during a pilot-scale deposition study

This has prompted a detailed review of the traditional microbiological treatment applications in numerous cooling tower water systems in all types of industry systems to see if there are any reasons that Legionella Bacteria could still be present

This paper presents the overall design of the test rig and initial results

and delamination—without the need for scaffolding or shutdowns

to help optimize chemical treatment

This chemical treatment method results in consistent chemical release

Nowaday the concept of pollution is involving new aspects of our life and the target given to the industry are getting more and more stringent: noise is one of the most important aspects of the modern pollution

all process water streams and utility water streams must be identified and their contaminants must be characterized

including investigation of potential potable water sources

Within the next few years this gap should be closed by CTI and ASME

by preventing treatment program upsets

case histories will also be presented to illustrate the effect some of these technologies have in sound sensitive applications
