Century Dictionary and Cyclopedia
- n. A device for cooling the water used in a steam-condenser or refrigerating-plant. It consists of a series of drip-pans placed one above the other in a water-tight tower, in combination with an air-blast. The hot water from the condenser is pumped into the uppermost pan, and falls from it in a shower to the next pan, and from this to the next, and so on until it reaches the reservoir below. A fan delivers a large volume of air under moderate pressure to the tower near its base, the air rising through the falling water and escaping through blinds at the top of the tower. The water passing through the tower is cooled from 15° to 30°, and can then be again used in the condenser.
- n. Attributive form of cooling tower
“As the eponymous movie from 2000 chronicled, hexavalent chromium dissolved from cooling-tower wastewater at a Pacific Gas & Electric facility leached into the groundwater beneath the town of Hinkley”
“Disadvantages: almost all heat gets released to ocean, which may not be allowed; consumes some energy to pump water from ocean (I don't know how this compares to cooling-tower power-consumption, but I think it's usually less).”
“From a visually damaging cooling-tower collapse in 2007 to a report last month of leaking radioactive tritium, compounded by misinformation the company gave to legislators, sometimes under oath, about the pipes involved in that leak, the odds of Vermont Yankee's winning permission to keep operating went from strong to dim.”
“As time ticks on, a series of problems at the plant - including a much-publicized cooling-tower collapse in 2007 and incorrect testimony from plant officials about underground pipes that surfaced just last week - have emboldened critics and dimmed the plant's hopes of winning a favorable vote.”
“The company began storing cooling-tower water in unlined ponds, assuring residents that the hexavalent chromium added to the water to prevent rust was safe for consumption.”
“Under the agreement, the company's thermal-equipment and services segment will design and supply a cooling-tower system at the Huaneng Qinling Power Plant.”
“You could be in the sales hub of a cooling-tower manufacturer in Akron or a claims-processing center in Hartford or some far-flung auditing gulag of the IRS.”
“Disadvantages: salt will cake on spray nozzles in the cooling towers, which is a major operational issue; salt concentration will rise and salt will precipitate in the cooling-tower pool and in other places if the concentration becomes too high; keeping the concentration down means maintaining cooling-water blowdown-flow (back to ocean, presumably) high enough, meaning that more water must be drawn from ocean (environmental impact); however, keeping the concentration low enough ensures that the concentration in the water released back to ocean won't be much higher than that in the ocean; higher capital cost than WSAC units; takes more space (bigger footprint) than that of same-capacity WSAC unit; CONSUMES SIGNIFICANT ENERGY, which is needed to blow cooling air up cooling towers.”
