Deposition characteristics of magnesium silicate and calcium carbonate on a heated surface in cooling tower water using city water as make-up was investigated. Flow velocity, bulk temperature and calcium hardness were maintained constant at 5.3 ft/ sec, 95°F and 150 ppm as CaCO₃ respectively whereas surface temperature varied from 105°F...
The fouling of cooling tower water was investigated as
a function of heater surface temperature and water quality.
In particular, the effects on fouling of the addition of
calcium in excess of the amounts required for saturation
were examined.
First, the average bulk water temperature was 97 ± 1
degree...
Scaling characteristics of calcium carbonate on a heated surface
in a deluged dry cooling system were investigated. Bulk temperature
of the deluge water was maintained constant at 90°F. Air flow velocity was maintained constant at 181 cfm., and deluge water flow was
maintained at the minimum level that provided thorough...
A computer assisted design model, developed for
undergraduate students to teach the basic principles of
humidification design, is developed and presented.
Beginning with the development of the differential
equations, the conversion to numerical code is presented,
followed by a series of applications to mechanical draft
in cooling towers, natural draft...
