Dual Source Water Supply Facilitates Power Plant Start-Upby Henry C. Hunt, Hydro Group Inc, Ranney Div, Westerville, OH, USA,
Abstract: The make-up cooling water supply for a four unit coal-fired steam turbine generating station required a peak demand of 28,000 gallons per minute (62. 4 cubic feet per second). Following hydrogeological testing, a radial Collector well was designed and constructed to provide an initial 7000 gpm (15. 6 cfs) supply. In order to meet the water supply needs for all four units, a surface water intake system was designed. Environmental evaluations were completed and a surface water system constructed to withdraw water from the adjacent river through a passive intake screen assembly submerged offshore in the river channel to provide the total, four unit, plant water supply.
