Condenser Tube Cleaning Systems (CTCS)
Our Features:
- World Class Technology
CTCS are backed by Fengqing’s exclusive tube cleaning technology. We have seven global leading patents. - Very High Ball Recovery
Fengqing’s patented technology allows very high ball recovery (collecting rate≧98%) and self-cleaning of the collecting area - Perfect Sealing
Self-latching mechanism design allows a perfect sealing of the grids and guarantees no escaping of cleaning balls from the circuit. - High Efficiency
Balls are immediately collected and reinjected in the condenser inlet. Balls do not remain in the collecting area waiting to find the ball inlet -
Optimal DesignSturdy design and rigid frame construction of the collecting grids.
Our Mechanism:
Cleaning of internal tube surface is accomplished by continuous circulation of sponge rubber balls with sizes slightly larger than the tube diameter. These sponge rubber balls are injected into the cooling water inlet header. The water flow carries these balls into the inlet water boxes, then through the tubes and finally into the ball strainer located at the cooling water outlet header.
Why Shall We Clean the Tubes?
Condenser tube cleaning is necessary as raw water induces different types of fouling which affects the inside of condenser tubes.
- Settling of suspended materials like silt, mud, slime
- Biological fouling due to the presence of bacteria / marine organisms in water
- Crystallization of soluble elements
- Formation of seashell colonies
Fouling can lead to the following results:
1.Corrosion under deposit
2.Corrosion created by the destruction of protective film inside the tubes
3.Reduction in the heat transfer capacity of the condensers
1.Corrosion under deposit
2.Corrosion created by the destruction of protective film inside the tubes
3.Reduction in the heat transfer capacity of the condensers
The efficiency of heat transfer in the condensers of steam turbines has a direct effect on the power generation. Experience has shown that a reduction of 1 mbar in the condenser vacuum of a 900 MW power unit leads to a final loss of about 1 MW of power output. An uncleaned condenser can easily lose over 10 mbar vacuum. In such a case the use of a CTCS will increase the power output by more than 10 MW. Hence it is extremely important to maintain the tubes of the condenser as clean as possible using highly efficient and reliable equipment.Sponge rubber balls are manufactured in our own plant. First grade natural rubber is used and blended with other material which gives them the final quality. Balls having different hardness and sizes are provided depending on the specific application.
Fengqing also supplies very good quality cleaning balls along with the CTCS; Improved cleaning efficiency; Preserved integrity of protective tube film; Maximised ball life.
