COOLING TOWERS INTRODUCTION
Forced draft cooling towers are specially designed to handle zinc sulphate solutions or highly corrosive liquids. They are equipped with distribution in highly resistant material.
The machines and processes of industry, as well as those devoted to human comfort and well being generated tremendous amounts of heat, which must be continuously, dissipated if those machines and processes are to continue to operate efficiency. Although this heat is usually transferred to a cool, flowing volume of water, final rejection is always to the atmosphere and, invariably, is accomplished by some form of heat exchanger.
The natural process of evaporation makes them very effective heat transfer mediums, although somewhat inefficient due to their limited surface area and their total dependence upon random winds.
Forced  draft  cooling  towers  are  very  similar  to  induced  draft  cooling  towers.    The  primary
difference is that the air is blown in at the bottom of the tower and exits at the top. Forced draft
cooling towers are the forerunner to induced draft cooling towers.   Water distribution problems
and recirculation difficulties discourage the use of forced draft cooling towers.
The cooling tower with plume abatement (also called hybrid or wet/dry) is an evaporative cooling tower combined with a dry heat exchanger, used to abate the cooling tower plume. This is the best available solution where local constraints are such that the presence of plume is not accepted in normal conditions (along motorways, airports, close to residential areas).
Plume abatement can be offered with mechanical draft cooling tower (cells) as well as with fan assisted natural draft
