92-12: Alkaline Phosphate - A New Direction for Phosphate Cooling WaterStringent environmental restrictions on chromate, and now on zinc, are forcing many plants to investigate alternative cooling water treatment technologies. A newly developed alkaline phosphate program operates in the same pH region as current alkaline zinc technologies. The alkaline phosphate program has broad calcium (80 1200 ppm as CaaCO3) and "M" alkalinity (100 350 ppm as CaCO3) application ranges. The new program provides excellent mild steel and

and "vibration" will apply to induced motion in mechanical components

the Southern California Gas Company replaced existing open cooling towers with "wet" Fin-Fan coolers

a comprehensive reliability study was made to ascertain the ability of the present 42-year-old recirculating water system to meet the anticipated load demand through the year 2010

but may not have the understanding they need of different motor types

Two methods which have been tested are chemical treatment with a phosphonate- polyacrylate blend and water softening

Circulating water-cooling to Cattenom nuclear plant (PWR 44 1300 MWe) is provided by four natural draft crossflow cooling towers

and efficiency changes will be presented

it is possible to prevent windmilling and provide secondary benefits that reduce installation and maintenance costs

maintenance and operational flexibility were a few of the many issues involved in the planning and implementation of this project

damage or design issues of the tower’s components on power generation

providing the knowledge to manipulate film chemistry for performance
