Cooling water pump for coal- and oil-fired | Sulzer
Cooling water pumps (CWP) provide fresh water to cool the exhaust steam in the condenser and pump it back to the wet cooling tower or the outlet of open cooling system. The major characteristic of the CWP is their high flow. In medium to large size coal- and oil-fired power plants, the CWP are vertical column type. In small coal and oil captive power plants, the CWP could also be horizontal ...

Effective optimization, monitoring, and maintenance of cooling equipment could deliver substantial electricity savings of up to 20% 7 (700 TWh), particularly if equipment has not been maintained for a long time,
Water cooling - Wikipedia
Water cooling is a method of heat removal from components and industrial equipment. Water may be a more efficient heat transfer fluid where air cooling is ineffective. In most occupied climates water offers the thermal conductivity advantages of a liquid with unusually high specific heat capacity and the option of evaporative cooling. Low cost often allows rejection as waste after a single use ...
