Power plants case studies: Ball cleaning systems and Cooling tower water conditioning
Power plant: Zeneng Changxing, Zeneng provınce China
Condenser Ball cleaning systems. Year of installation: 2010
A system was installed at the condenser of a coal operated 300 mW unit at the Changxing plant. A second system using a ball cleaning system from a well known manufacturer was used as reference in a comparative performance study that lasted for 18 months.
Both condensers were cleaned and operated under the same conditions. Results of the study are as follows:
- Data collected showed that the unit using CQM’s ATCS system required 0.9 gram /kW of coal less than the other unit.
- Unlike the other condenser, cleaning factor was preserved, all tubes stayed clean, and no balls were lost at the unit using CQM’s ATCS system
- As the result of the better performance and clear savings, three additional units of CQM’s ATCS system were installed at Changxing, replacing the existing ball cleaning system.

Condenser Ball cleaning systems. Year of installation: 2005
An ATCS ball cleaning system was installed at the steam turbine condenser in 2005. Tubes are perfectly clean and the system works at satisfaction since the commissioning, as IREN ENERGIA Moncalieri Italy ATCS.
SRCT Large cooling towers
Power plant: Fengtai, China
SRCT systems for water conditioning. Year of installation: 2014
As a result of a successful pilot study at Taijo power plant, it was decided to treat the cooling water of the Fengtai power plant using CQM’s SRCT systems.
The project was commissioned in 2014. CQM prepared twenty interconnected systems in four containers. Each contained contains fice systems, a control room, electrical connections and the water inlet and outlets. The infrastructure was prepared at the power plant ahead of time. The containers were shipped, placed at their determined locations, connected to power, water and communications and started working.
20 SRCT systems are currently conditioning the water for two parabolic towers of 600 mW, 75,000 m3/hr cooling tower flow rate and a water reservoir of 130 meters of diameter each.
The systems were installed to stop the use of chemicals against biological fouling, corrosion and scale. The only chemical intervention to the towers is to balance the pH to 8.5.
Fengtai’s experts team commented at the acceptance meeting:
“This project completes the relevant test requirement of the original project application. In this project the following work has been completed: The water quality control by electrolysis approach in circulation water drainage quantity control, anti-scaling anti-corrosion and disinfection research. The economic benefit is obvious.”
The video below shows the installation of the systems and the inside of one of these containers.
