Fouling and Scaling of the Condenser Tubes happens to cause a major impact on a condenser’s overall performance, which will eventually result in the loss of Power Generation. GEA BGR Condenser Online Tube Cleaning System is installed to facilitate continuous cleaning of the Condenser Tubes with the Power Plant in operation. Condenser Online Cleaning is carried out by passing slightly oversized Sponge Rubber Balls across the condenser tubes. A condenser tube cleaning system is a closed recirculating loop through which the Schmitz Cleaning Balls are injected into the condenser Cooling water. The cleaning balls passthrough the tubes to keep the tube free of scaling formation. The ball strainer located downstream of the condenser collects the cleaning balls and reinjects them through a ball recirculating pump skid with an injection nozzle installed on the condenser cooling water inlet pipes. Understanding the growing significance and with the utmost care for the environment, these cleaning balls are prevented from getting out of the closed-loop system and ensuring ball collection ratio is designed to maximum.
