6.3.1 Debris filter
Coastal power station condensers are more vulnerable to the intake of debris such as mussels, fish, wood, plastic and fibrous materials, than inland power station condensers. One solution to prevent the blockage of condenser tubes is the installation of a debris filter in the CW inlet side of the condenser.
All particles in the cooling water larger than 10 mm are kept in the filter and rinsed away through the debris discharge. Throttling of the filter inlet isolating valve causes a change in flow direction near the screen, creating a rinsing effect. The discharge water quantity
