Do power and industrial plants have auxiliary cooling water systems?

In previous parts of this series, we examined many issues related to primary cooling water treatment at power and industrial plants. However, most large plants have a number of closed water systems that provide auxiliary cooling to such equipment as pump bearings, lube oil coolers, generator hydrogen coolers and so forth. Figure 1.

Do new power plants use once-through cooling?

This type of system is currently widespread in the eastern US Very few new power plants use once-through cooling, however, because of the disruptions such systems cause to local ecosystems from the significant water withdrawals involved and because of the increased difficulty in siting power plants near available water sources.

What is a once-through cooling system?

Once-through systems were initially the most popular because of their simplicity, low cost, and the possibility of siting power plants in places with abundant supplies of cooling water.

Does a closed water system provide auxiliary cooling?

However, most large plants have a number of closed water systems that provide auxiliary cooling to such equipment as pump bearings, lube oil coolers, generator hydrogen coolers and so forth.
