Tower Location

Cooling Towers. The cooling tower location relative to the prevailing wind direction should be such that the wind hits the short side or the side perpendicular to the inlet louvers. This helps balance the air flow to the two inlet sides. 

Unlike the Odeillo installation, previously described, where a held of heliostats finally focus their energy to a small aperture by way of a huge parabolic reflector, in the solar tower approach, the energy from each mirror is directed to a central receiving tower, located high above the field, as... 

The cooling tower location with regard to its proximity to a susceptible population. 

Location of the RO system relative to the cooling towers is a concern. In most facilities, the RO is not located near the major cooling towers. There may be a small, local tower located nearby, but discharging to this tower may be difficult as the RO reject could be a major portion of the make-up flow to the tower. Pipelines must be run from the RO to the major cooling towers to allow discharge of the RO reject to these towers. 

In many cases, the vapor rate changes over the length of the tower, and the theoretical diameter based on the allowable vapor velocity varies. Occasionally, two different diameters are used for different sections of one tower. Cost considerations, however, usually make it impractical to vary the diameter, and the constant diameter should be based on the tower location where allowable velocity and throughput rates require the largest diameter. 

The meteorological sensors are mounted at the top of a 7 m tower, located in a clearing 40 m south of Spruce Tree House. The sensors are thus about 5 m above the elevation of the test walls, and just above the forest canopy within the canyon. The exposure of the instruments was chosen to reflect accurately the specific environment experienced by the test walls and Spruce Tree House. The non-intensive experiments are located in the same clearing, on a separate mast about 2.5 m tall. In addition, temperature transducers and surface time-of-wetness sensors have been mounted on the test walls. These parameters are also recorded on digital tape. 

FIGURE 8 Changes in nonmethane hydrocarbon (isoprene) emissions predicted to accompany a shift from savanna grassland to a savanna woodland at the La Copita site in southern Texas (based on Guenther et al, 1999). Predictions from a coupled succession-NMHC emission model are compared with values measured from flux towers. The measured values shown for the historic landscape are from a tower located in a savanna grassland landscape with low woody cover. 

Tower location relative to the prevailing wind direction to minimise contamination problems from dust, gases and other airborne components that may occur. 

Solar One - A solar thermal electric central reciever power plant ("power tower") located in Barstow, California, and completed in 1981. The Solar One had a design capacity of 10,000 peak kilowatts, and was composed of a receiver located on the top of a tower surrounded by a field of reflectors. The concentrated sunlight created steam to drive a steam turbine and electric generator located on the ground.

Wind field measurements were made with 19 stations using two-axis cup-and-vane anemometers (Met-One) located 2 m above the ground. These were positioned both upwind and downwind from the release point. Meteorological boundary layer measurements were made on a 20-m tower located 130 m upwind of the spill point and 25 m off the centerline of the test grid. This tower was installed with five levels of 1000 Cl platinum RTD mounted in aspirated solar shields at heights of 1, 2, 4, 8, and 16 m. In addition there were three Gill bi-vane anemometers installed at 1, 4, and 16 m to measure atmospheric turbulence. An additional 15 bi-vane anemometers were installed at heights of 1, 5, and 11 m on five towers located downwind of the spill point. The bivane data were not provided by LLNL to WRI, but some of the data are provided as plots in the Falcon Data Report (Brown et al., 1990). 

The downwind instrumentation grid of multiple levels of sensors was defined by three arrays, at 50, 150, and 250 m from the downwind end of the vapor barrier fence. On these downwind array towers Type K thermocouples were positioned at four heights on the 50-and 150-m arrays and three heights on the 250-m array, to measure cloud temperature as it moved downwind. The exeeption to this was the tower located on the centerline of the 150-m array, which had four levels of RTD sensors rather than thermocouples. Between tests 3 and 4, two towers and their associated instrumentation were moved from the 50-m array and added to the 150-m array to increase the width of the 150-m array. This was done based on the wider than anticipated clouds created during the first three experiments.

Heat picked up by the water on the shell side of the heat exchanger loop is dumped to the secondary system sump tank. The cooling tower loop then draws its suction from the sump tank and pumps the heated water through a cooling tower located on the roof of the console area. Finally, the cooled water is returned to the sump tank to restart the cooling cycle. 

The first investigated historic building is a bell tower (Fig. 1), about 37.0 m high and built in stonework masonry (Gentile and Saisi 2013). The tower - located in the small town of Arcisate (northern Italy) - has a square cross section, with sides of 5.8 m, and is connected to the church Chiesa Collegiata on the East side and partly on the South side. The church, dedicated to St. Vittore, dates back to the fifteenth century and replaced a more ancient church, built in the fourth century and modified in the eleventh century. Probably the tower foundation dates back to the late Roman age, as well.
