A cuilin touer is a heat rejection device that rejects waste heat tae the atmosphere through the cuilin of a watter stream tae a lower temperature. Cuilin touers may either use the evaporation o watter tae remove process heat an cool the workin fluid tae near the wet-bulb air temperature or, in the case o closed circuit dry cuilin touers, rely solely on air tae cuil the workin fluid tae near the dry-bulb air temperature.
Common applications include cuilin the circulating watter used in ile refineries, petrochemical an other chemical plants, thermal pouer stations an HVAC systems for cuilin biggins. The classification is based on the teep o air induction in tae the touer. The main teeps o cuilin touers are natural draft an induced draft cuilin touers.
Cuilin touers vary in size from small roof-top units tae very muckle hyperboloid structures (as in the adjacent image) that can be up tae 200 metre (660 ft) tall an 100 metre (330 ft) in diameter, or rectangular structures that can be over 40 metre (130 ft) tall an 80 metre (260 ft) long. The hyperboloid cuilin touers are often associated with nuclear pouer stations, although they are also used in some coal-fired plants an in some muckle chemical an other industrial plants. Although these muckle touers are very prominent, the vast majority o cuilin touers are much smaller, including many units installed on or near biggins tae discharge heat from air condeetionin.
