Drift elimination

Drift is entrained water in the tower discharge vapors. Drift loss is a function of the drift-eliminator design, which typically varies between 0.1 and 0.2 percent of the water supphed to the tower. New developments in eliminator design make it possible to reduce drift loss well below 0.1 percent. [Pg.1165]

Some manufacturers of internal cooling tower components, specifically fill material and drift eliminators, have products produced from less easily ignited plastic that have been tested by a nationally recognized testing laboratory and determined to have sufficient fire resistance or reduced flame spread ratings that when, and only when, used in an otherwise noncombustible cooling tower, do not require fixed automatic fire protection.

The total volume of air required has a direct bearing on the required area of drift eliminators. Thus, it is indirectly related to the tower size itself. [Pg.136]

A large capacity sea-water cooling tower is designed with a drift eliminator to drastically reduce the drift carry-over. The drift carry-over from the tower has in fact been reduced to only an order of 6 to 7 X 107 of the quantity of sea-water circulated for cooling, or is as low as 1/2000 or less as compared with 0.2% in the conventional fresh-water cooling tower. The present paper gives an outline of the service results of this cooling tower. 5 refs, cited. [Pg.285]

The timber used in this type of cooling tower is commonly pressure-treated redwood, Douglas fir, and other wood species, the preservative being chromated copper arsenate or, more usually today, acid copper chromate. Despite the wood preservative, it is not uncommon to find wood decay and biological fouling of the plenum area and drift eliminators. [Pg.11]

The makeup water requirement is, in turn, the sum of the evaporation rate plus water losses. Water losses are drift or windage (which, in modern cooling towers, is minimized by efficient drift eliminators), deliberate bleed or purge of water (normally to maintain cycles of concentration within a specified range), and any leaks. Thus for any reasonably accurate calculation concerning the quantity and costs of chemical treatment, it is essential to have factual information on the makeup and/or evaporation rate of a cooling system and also on the cycles of concentration, in addition to various water analyses.
