“COOLING TOWERS”
ANDREW HOWELL – XCEL ENERGY
BIO: Andrew Howell is a Senior System Chemist for Xcel Energy, and has worked for the company and its predecessors since 1982. His work has included a variety of chemistry-related problem solving investigations, frequently involving corrosion and related concerns. He has B.A. and M.S. degrees in Chemistry from the University of Missouri-Columbia, and a Ph.D. in Applied Chemistry with a minor in Metallurgical Engineering from the Colorado School of Mines.
ABSTRACT: Several technologies are available for condensing steam in power plants. Increasing difficulty with obtaining adequate cooling water supply for new generating units has required some plant designs to use dry or hybrid (wet + dry) cooling systems. While necessary in some cases, these options have significant downsides that must be considered in planning for construction and operation.
DANIEL CICERO - NALCO
ABSTRACT: Every power plant wants to be a good corporate citizen of the community in which it resides. Every power plant wants to minimize its environmental impact. Those desires must be balanced with the needs of the community for low-cost power. This presentation will discuss three cases where power plants achieved that balance. In one case, using water chemistry modeling allowed a plant to reduce withdrawals from a stressed waterway. In another, changing water chemistry reduced the impact of the power plant on the local community. In a third, the ability to respond to changing water quality reduced water costs and demands on the local water supply.
TRENT GATHRIGHT - OVIVO
BIO: Trent T. Gathright, Sales & Marketing Manager, Cooling Water Products, Ovivo is a native of Houston, Texas has served 34 years in the field of mechanical water filtration for cooling water intakes and condenser protection. His experience with screening plant equipment includes design, manufacturing, rebuilding, installation and research & development. He commonly assists EPC & A/E firms with cooling water system designs and upgrades. Research includes underwater studies of fish behavior when encountering rotating screening devices leading to the development of hydraulically stabilized screening elements to increase survivability of juvenile fishes, (EPRI Proceedings, March 1988). This is commonly known as the S.I.M.P.L.E.® design, and is recognized as BTA for 316(b). Other developments include a patent for a “Retractable Traversing Trash Rake” (RTTR) for adaptability to existing structures to mitigate loss of cooling water at the primary intake. These are currently installed at multiple nuclear power stations. Mr. Gathright is currently employed by Ovivo USA, serving as the Sales & Marketing Manager in the Energy Group for Cooling Water Products.
ABSTRACT: Cooling Water Issues
Numerous factors affect power plant cooling water at both once-through and closed cycle types. Various methods have been developed to deal with debris at both type plants including indigenous debris, foreign blown in material and element disintegration. Pending 316(b) may also affect how make-up water intakes are handled. Ovivo will briefly address different type screens and 316(b) alternatives.
