Abstract:
ON January 31, 1993, the north side of the No. 4A mechanical
draft-cooling tower serving Columbus Southern Power's Conesville
Unit 4 collapsed; forcing the 800 MW coal fired generating unit
out of service. The cause of catastrophic structural failure,
tower reconstruction program and considerations for preventing
similar failures in the future will be reviewed.

Abstract:
The major feasibility issues concerning the applicability of
Mechanical Draft Seawater Cooling Towers for large-scale
petrochemical development in the hot-humid Arabian Peninsula
(Gulf) region were investigated. Issues addressed were tower
thermal performance, permissible hot and cold-water
temperatures, scaling and bio-fouling, drift and impact on
corrosion, environmental impacts, O&M concerns, and
life-cycle costs. It was found that seawater cooling towers can
satisfy the cooling needs of large-scale petrochemical
development in the hot humid Gulf region, without significant
problems. Cost of cooling was found to be less than the
conventional once-through system normally used. Based on the
findings of this study, plans are underway to double the size of
one of the largest petrochemical complexes in the world, located
in the region. The findings of this study constitute a major
step forward for the cooling technologies industry.

Cooling Tower Basin Evaluation and Repair

Abstract:
Mechanical draft cooling towers are critical fixed assets that need to be maintained and remain in service in order to cool various plant operations and systems. Essentially, the cooling tower basin in mechanical draft technology serves a two-fold purpose, one as containment for the cooling water and two as the foundation for supporting overlaying "fill" structures. Almost all of these basin structures are constructed of conventionally reinforced concrete, either partially or totally placed below grade. Their service environment subjects them to various aggressive deterioration mechanisms including embedded metal corrosion, original construction defects, environmental degradation (i.e. freeze-thaw, algae growth, etc.) as well as chemical attack resulting in erosion and structural section loss. Since these structures contain process water and function as support foundations, the existing condition of these structures should be evaluated regularly and repairs performed should conditions warrant, on a timely basis. Evaluation techniques exist, both non-destructive (NDT) and semi-destructive (SDT), which can serve as tools in assessing in-site conditions, either on or offline. Additionally, the paper will highlight case histories of cooling tower basin evaluations and subsequent repair program implementation.
