97-12: Maximizing Fan Performance Miscellaneous

97-12: Maximizing Fan Performance MiscellaneousMaximum fan performance usually means maximum airflow for minimum horsepower, but it also means maximum service life and sometimes minimum noise. This paper describes the many points to consider beginning with selection of an optimum operating point and many factors concerning the fans operating environment. This includes tip clearance, obstruction to airflow, vibration, blade loading, resonant frequency concerns and other important parameters.

EDF made tests on thermal performances thanks to Mistral Test facility and installed pieces of different types of packing in weighing machines onsite

This includes tip clearance

Coupon corrosivities measured

The model was used to understand the main phenomenon leading to ice transport and accumulation

cooling water discharges are being studied for potential reuse applications

The cleaning involved structural modifications of nine (9) of the eleven (11) cells and a diversion of 100

If the enhanced cooling tower is operated as an evaporative chiller that can completely displace refrigeration equipment

This paper will discuss the analysis of these waters and instrumentation that allows careful monitoring to be achieved

a number of sediment control vanes previously placed in front of the intake will be removed to facilitate downstream ice transport
