84-09: Cold Weather Operation of Mechanical Draft Cooling Towers Fire Protection

84-09: Cold Weather Operation of Mechanical Draft Cooling Towers Fire ProtectionAnnually, millions of dollars are spent in repairing ice damaged cooling towers. Most of this damage could have been avoided had reasonable cold weather operating procedures been in effect. This paper presents a guideline for the development and implementation of cold weather operating procedures for evaporative cooling towers. Emphasis is placed on the preparation of the tower and its operating personnel for winter operating conditions. The theory of

longer periods of run time and reduce under-deposit corrosion

and formation of horrendous amounts of foam until it was found that these troubles could be minimized by pre-treatment with lime

Stagnant water films have 8

Legionella testing is required and chlorine residual control ranges are specified

In order to do this

retention of drift on foliage

Preventing microbial growth in recirculating cooling systems is crucial to maintain productivity at your site and extend the life of your capital assets

allowed comparison of product features and application variables on an equal basis

plant personnel are looking at cooling tower blowdown recycle and recovery as a method to conserve water

Such layout provides recirculation effect

selection of critical parameters and performance standards

The paper gives the guides lines of the fill design in relation with the fouling and the scaling resistance
