TP26-25 Axial Flow Fan Design for Large Cooling Towers Utility Industry

TP26-25 Axial Flow Fan Design for Large Cooling Towers Utility IndustryThe design of axial flow fans for large cooling towers comes with unique challenges due to their large size, high airflow needs, and the demanding environments in which they operate. These fans face operating conditions that go far beyond those of smaller industrial fansall while maintaining high efficiency. This paper outlines the mechanical design and engineering of a rugged, high performance aluminum axial fan that meets these demands.

The discussion will be limited to an open recirculation cooling water system

Variable frequency drives (VFD) were added in 2003

Mechanical Draft

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

000 and a Scope 3 CO2 reduction of 1

How do you determine "end points" where scale inhibition is lost

cooling ranges and approaches

Controlled cavitation however can yield to beneficial outcomes when applied to water treatment for cooling towers

The advanced test methods have developed foundational data that show this cooling system treatment program’s ability to prevent scale and corrosion across wide pH/alkalinity ranges in the presence of high chloride and high sulfate

Since that presentation

This paper presents laboratory and field data that describes the very successful application of a new microbiocide for control and removal of persistent and heavy algal growths
