BALL MONITOR
Keeping the correct number and size of cleaning balls in condenser tubes isessential for efficient power plant maintenance. As a leader in Condenser TubeCleaning Systems, TECHNOS has developed tools to guarantee betterfunctioning of equipment.
CUSTOMER BENEFITS
Increase condenser safety
Guarantee circulation of good balls in
the system
Records the state of the system to
guarantee performance of the
condenser
Life time extension of the condenser
Prevent waste of usable balls
WHAT HAPPENS WHEN BALLS ARE NOT
MONITORED ?
Leaving worn-out balls in circulation can have COSTLY
CONSEQUENCES: LOSS OF CONDENSER EFFICIENCY,
and therefore LOSS OF PRODUCTION and eventually
leading to the potential need to perform risky mechanical
or chemical cleaning on dirty tubes. Operators
periodically check the number and diameter of the
balls in circulation. However, relying on a manual
sieve with calibrated holes to identify worn-out
material is time consuming and often leads operators
to renew the complete ball load at routine intervals.
This can obviously lead to excessive ball consumption
and its associated costs.
HOW CAN THE BALL MONITOR HELP YOU ?
The TECHNOS Ball Monitor CONTINUOUSLY SORTS
AND REMOVES undersized balls and constantly monitors
the ball count to assure continuous cleaning of tubes. The
Ball Monitor can be used with the TECHNOS Continuous
Ball Feeding system for worry free maintenance.

BALL SORTER
SIZING THE EXTRACTION
THRESHOLD
The minimum diameter at
which the balls must be sorted
is defined by the inside diameter
of the condenser tubes. Although
it is fixed at the manufacturing
stage of the Ball Sorter, it can be
adjusted slightly to take into
account any possible change in
ball specification.
REMOVING SPENT BALLS
Once sorted, worn-out balls areprevented from returning into
the main ball recirculation circuit
and are stored inside a spent ball
basket. This basket must be
emptied periodically by opening
the drain valve.
PROPERTIES AND QUALITIES
- Ageing will not affect its
performance
- Adjustments are easily made by
means of a variable orifice plate
- The Ball Sorter is autonomous
BALL COUNTER
The Ball Counter continuously
monitors the number of balls
in circulation and activates an
alarm when their number falls
below a pre-set value.
PROPERTIES AND QUALITIES
A light barrier of 40 I.R.
beams screens a glass pipe
section fitted on the ball-
recycling circuit. All recycled
water flows through this glass
pipe and each ball in
circulation is counted as it
crosses the light barrier while
debris and air bubbles pass
through unrecorded.
A programmable logic
controller receives information
from the light barrier and a
high-speed entry device
records the number of ball
passages within a measured
period.
Software calculates the
number of balls in
circulation based on the ball
circuit configuration and its
nominal operating
characteristics. The Ball
Counter must be calibrated
during commissioning of the
equipment.
