and condenser scale reduces efficiency in boiler and cooling tower operations,
because all forms of scale possess a low degree of heat conductivity.
The presence of scale is like spreading a thin film of insulation
across the path of heat transfer, thus reducing boiler and condenser
rate of heat transfer may be reduced as much as 15% by the presence of scale.
In a 200 hp. boiler, a 15% loss in heat transmission increases fuel
costs as much as $120,000 a year based on a 10-hour day, 260-day year.
more important than heat loss is the effect scale has in causing boiler metal
to overheat. This condition
results in tube failure. If sufficient scale is formed, the insulating
qualities of the scale can cause the tubes to heat to more than 900°F/482°C.
This is usually the maximum temperature that is considered safe for
boiler tubes. Costly repairs and
boiler downtime are the result of such a condition.
high boiler water pressures and temperatures, there is less temperature
difference between the boiler water temperature and the failing temperature of
the metal. Consequently, tube
failures result at higher boiler water pressures with scale of considerably
less thickness. This condition
explains the need for close control of boiler water conditions in high
pressure boiler operation.
