Water Cooling Tower – Cooling Water Systems are an essential part of process operations for many industries and public buildings. There are four problems commonly associated with water systems; corrosion, scale, fouling and microbiological contamination.

Clearwater products have been specifically designed to optimise system performance, cleanliness and heat exchange efficiency. Clearwater is the acknowledged leader in stable halogen treatment technology.

Regulatory requirements (ACOP L8) specify that cooling towers need to be controlled in order to prevent the proliferation of legionella bacteria. Legionnaires disease has become a major health and safety issue. Clearwater have the knowledge and experience to ensure that our clients comply with Government legislation

Square Cooling Tower

Square Shaped Cooling Tower[/caption]Square shape cooling tower is a design in which the air flow is directed perpendicular to the water flow (see diagram below). Air flow enters one or more vertical faces of the cooling tower to meet the fill material. Water flows (perpendicular to the air) through the fill by gravity. the air flow is directly opposite to the water flow (see diagram below).

Air flow first enters an open area beneath the fill media, and is then drawn up vertically. The water is sprayed through pressurized nozzles near the top of the tower, and then flows downward through the fill, opposite to the air flow. The cool water absorbs heat from the hot process streams which need to be cooled or condensed, and the absorbed heat warms the circulating water. The warm water returns to the top of the cooling tower and trickles downward over the fill material inside the tower.

Square shape cooling tower contacts ambient air rising up through the tower either by natural draft or by forced draft using large fans in the tower. That contact causes a small amount of the water to be lost as windage (W) and some of the water (E) to evaporate. This method works on the principle that continuous particle removal will keep the system clean. Manufacturers typically package side-stream filters on a skid, complete with a pump and controls. For high flow systems, this method is cost-effective. Properly sizing a side-stream filtration system is critical to obtain satisfactory filter performance.

Natural Draft Cooling Tower

By | Cooling Tower | No Comments

“Natural Draft Cooling Tower” Natural contacts ambient air rising up through the tower either by forced draft using large fans in the tower. Natural draft is utilizes a tall chimney. Warm, moist air naturally rises due to the density differential compared to the dry, cooler outside air. Warm moist air is less dense than drier air at the same pressure.

This moist air buoyancy produces an upwards, current of air through the tower.Natural that appears like a natural draft setup, though airflow is assisted by a fan.This association is misleading, as the same kind of cooling towers are often used at large coal-fired power plants as well. Conversely, not all nuclear power plants have cooling towers, and some instead cool their heat exchangers with lake, river or ocean water.

The heat required to evaporate the water is derived from the water itself, which cools the water back to the original basin water temperature and the water is then ready to recirculate. Natural cooling towers have become the design standard for all natural-draft cooling towers because of their structural strength and minimum usage of material. The hyperboloid shape also aids in accelerating the upward convective air flow, improving cooling efficiency. These designs are popularly associated with nuclear power plants. That contact causes a small amount of the water to be lost as windage (W) and some of the water to evaporate.
