COOLING TOWER

COOLING TOWER :



A cooling tower removes heat from a process and rejects it to the atmosphere through the process of evaporation. In a typical application, water is pumped through a process or process machinery where it removes heat. The warm water is pumped outside to the cooling tower where it is distributed over a series of plastic sheets (fill) inside the cooling tower. An electrically powered fan moves air through the tower and causes a small portion of water to evaporate which cools the rest of the water left in the cooling tower. This process operates more efficiently and provides much cooler water temperatures than simple fan-cooled air coils.
Thermal Care offers cooling towers with corrosion resistant fiberglass exteriors and internal supports that are lightweight, require low maintenance, and are designed for years of dependable service. Our FC Series Cooling towers and FT Series Cooling Towers  can withstand the harsh conditions of industrial environments much better than traditional galavanized steel cooling towers and are the smart choice for industrial cooling towers.
A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed circuit dry cooling towers, rely solely on air to cool the working fluid to near the dry-bulb air temperature.
Common applications include cooling the circulating water used in oil refineries, petrochemical and other chemical plants, thermal power stations, nuclear power stations and HVAC systems for cooling buildings. The classification is based on the type of air induction into the tower: the main types of cooling towers are natural draft and induced draft cooling towers.
Cooling towers vary in size from small roof-top units to very large hyperboloid structures (as in the adjacent image) that can be up to 200 metres (660 ft) tall and 100 metres (330 ft) in diameter, or rectangular structures that can be over 40 metres (130 ft) tall and 80 metres (260 ft) long. The hyperboloid cooling towers are often associated with nuclear power plants,[1] although they are also used in some coal-fired plants and to some extent in some large chemical and other industrial plants. Although these large towers are very prominent, the vast majority of cooling towers are much smaller, including many units installed on or near buildings to discharge heat from air conditioning.

THEORITICAL YIELD VS ACTUAL YIELD

Image
THEORITICAL YIELD VS ACTUAL YIELD : Amounts of products calculated from the complete reaction of the limiting reagent are called  theoretical yields , whereas the amount actually produced of a product is the  actual yield . The ratio of  actual yield  to  theoretical yield  expressed in percentage is called the percentage  yield
