Determination of flow throttling conditions in a system used to transport water from cooling towers to turbine condensers

Water from cooling towers is transported to condensers via a system including screens that are to arrest mechanical impurities and not let them pass into condensate pumps. These screens, when clogged, often cause throttling the water flowing to condensers, hence, interference in power unit operation. Thus, it is of importance to allow for the screen clogging extent monitoring from the power unit control room in order to adapt periodical cleaning frequency to the actual needs. The authors who provided solution to this problem have used an original answer allowing one to observe the system in operation and flow conditions of water stream from cooling towers to condensers and also permitting possible decision taking about cleaning the screens installed in the system [1, 2].
