00-15: Collapse of the Conesville 4B Seven Cell Mechanical Draft Cooling TowerEarly in the morning of July 12, 1998, one of the two seven cell mechanical draft cooling towers serving American Electric Power's (AEP) 780 MW Conesville Unit 4 suddenly collapsed into the cold water basin. Investigation into the cause of the catastrophic collapse and resulting methodology for evaluating the structural integrity of similar towers on the AEP System will be reviewed. Structural upgrades incorporated into the replacement tower design

the low noise demands had an impact on the selection on all other equipment like E-mothers and gearboxes

This paper correlates chiefly noise data measured at Exxon process plants into a prediction technique for estimating induced draft cooling tower noise in communities adjacent to a plant

energy consumption and the size or number of units required

The timely removal of such debris form the cooling towers is essential

This document serves as a guideline for techniques and instrumentation that can be used to measure airflow and other fan performance parameters on induced draft in situ heat rejection equipment having axial fans

due to its good corrosion resistance and heat transfer characteristics

The repack not only restored tower performance

This paper will present a study of an architectural louver enclosure and its influence on the performance of the tower when less than ideal clearances are achievable

In recent years there has been considerable debate on the merits of designing around lower nominal condenser water flow rates with a higher range in order to improve system lifecycle costs

Continuous diagnostic and control procedures have made marked improvement in cooling system operation
