Cooling water pump (CWP) for biomass wasteCooling water pumps for biomass firing applications are typically horizontal axially split or end suction type. Vertical turbine type pumps are also available when required.
-
Cooling water pump (CWP) for gas-firedCooling water pumps (CWP) provide the 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 gas-fired combined-cycle power plants, the CWP are vertical column type. In small power plants, the CWP could also be horizontal axially split type.
