This Capstone Project will address the erosion phenomena on the impeller blades of the main cooling water pumps in Thermal Power Plant (TPP) “Kosova B”. These are vertical mixed flow pumps and are part of the cooling system that play an important role in TPP “Kosova B”. In this investigation I will study the line between the cooling tower basin and the pumps intake. This line includes the pipe with a 2220 [mm] diameter through which the water, from the cooling tower basin, goes into the pumps intake. In fact we have two lines where one is for unit B1 one and other is for unit B2. For this investigation I will analyze only one of them, because these two lines are physically the same. I am calling this line the “suction line”. This suction line is important for my investigation because it is characteristic of all vertical mixed flow pumps where the majority of failures result from the improper design of this line.
