The importance of water in the cooling tower industry - Water (part 10)

WHAT ARE THE CONSEQUENCES OF A COOLING TOWER OPERATING AT LOW EFFICIENCY?

The tower is part of a system designed to dispose residual waste heat from the production plant or other primary system. The lower efficiency of the tower affects the performance of the primary plant with considerable waste of energy and, most of all, reduction or lack of production.

CONSTRUCTION OF A COOLING TOWER: TIPS ON ITS COMPONENTS AND THEIR USE.

As we saw, the cooling tower is an essential part of the plant system and, generally, it is separated from the primary plant system to which it drives.

The cooling tower is normally ignored until it goes into failure. Hence, the choice of components is of utmost importance.

Choose a tower made of stainless steel. Towers that need to be installed in heavy environments, such as chemical industries, choose polyester reinforced with glass fiber.
We have witnessed towers that have been operating for over 30 years, in these heavy environments, in perfectly stable structure.
Other useful tips and / or necessary will be exposed our next documentation work for publishing:

The importance of water in the cooling tower industry - Water (part 7)

Process plants that can be cooled with evaporation systems.
The importance of disposing quantity of energy.
Efficiency of the cooling system.

From what has been written on this subject, the disposal of heat from evaporative cooling towers use something in particular, that is, disposing large amounts of heat from the water by means of the air: two natural elements.
Heat disposal has, therefore, a relatively low cost.

To name a few examples where towers are used:
(a) disposing heat from the various refrigeration groups and city building air conditioning condensers.
(b) in industries such as oil refineries, chemical plants,
(c) in industrial process plants for the production of food products,
(d) in thermoelectric power plants,
(e) in geothermal systems.
(f) …
Obviously each type of installation has different requirements for heat disposal (amount of cooled water). Temperatures and their range must be designed appropriately and carefully, and, most of all, the air thermal characteristic data to be considered for cooling tower design.
Air data has to include temperature, humidity and altitude related to the location of the tower. These three values (temperature, humidity, altitude) are very important.
If the data is not chosen correctly, this can lead to the wrong tower sizing, up to three or four times higher, or lower, than the actual needs of the system.

If the tower sizing is higher than the correct value, this will lead to waste of material and, hence, higher cost of the system. On the other hand, if faulty sizing will lead to equipment that is not adequate to the system, hence, useless!

NERI Calculator

Calculator www.nericalc.com
When it comes to evaporative water cooling towers, whether you're are part of the design team or maintenance operations, NERI Calculator helps ensure that the functionality of the tower is optimal and efficient, hence, maintaining plant's productivity at maximum level.

Design
For maximum efficiency, in the design phase of the evaporative cooling tower project, NERI Calculator returns the optimal size of the tower needed to serve a predesigned plant system.

Maintenance
In normal maintenance operations, NERI Calculator verifies tower performance based on the actual tower data.

What are the risks of a poor functioning tower?
  • Tower driven system will not function correctly
  • Loss of productivity of the plant
  • Could cause heavy damage
  • Impact on the Environment
The cost of running a bad designed cooling tower could be high!
NERI Calculator covers two type of evaporative water cooling towers:
  • Counter-flow: a water cooling tower design where the air-flow is directly opposite of the water-flow.
  • Cross-flow: a water cooling tower system design in which the air-flow is directed perpendicular to the water-flow. Air flow enters one or more vertical faces of the cooling tower to meet the fill material.
If your tower is counter-flow, then try our NERI Calculator tool for free. When you sign up, we offer you a 1-day free trial of 50 calculations.
If your tower is cross-flow, then contact us and we'll do the calculations for you.
NERI Calculator is not only used for design purposes, but it's a tool to use always during on-going activities for monitoring and controlling cooling tower performance.

“Prevention is better than cure”
NERI Calculator will prevent damages resulting from a poorly functioning cooling tower, by verifying that the data is correct and/or has not been modified. Poor functioning cooling towers will have bad consequences not only on the cooling tower, but mostly on any production system served by the tower. All this damage and loss can be translated in huge economic loss!
