Study on Trash Bars and Its Debris-Cleaning Technical Status in Water Intakes of Power Station

Abstract

Trash bars and its debris-cleaning technical status in water intakes of water resources, hydropower engineering, heat-engine plant and nuclear power station have been analyzed. It’s shows that problems such as vibration, broken, blocking, corrosion and poor cleaning efficiency exist extensively in the daily use of trash bars, which bringing great hidden danger to the security and steady operation of power station. Therefore, the structure, weld process, debris-cleaning type, through-bars velocity and head loss of trash bars should be optimized based on the detailed analysis of technical features of the trash bars and combining the power station site characteristics, reflecting the best technology available(BTA) for pointing out the research trend of trash bars and its debris-cleaning technology.
