Abstract:

Shoubrah El-Khimah Power Plant was built in 1982. Its peak capacity is 1200 MW, generated by four units, three of them having one cooling water intake. The cooling water pumps suffer from severe cavitation. An extensive hydrographic survey has been conducted at the pumping station and at the adjacent Nile River. The data show that the river flow and consequently the approach flow conditions are the main source of the unfavorable flow characteristics inside the pump intake, leading to vortex formation and swirl at both the intake and the pump impellers. A temporary solution is to use stainless-steel impellers. The long-term solution is to modify the intake.
