1) The actual power consumption of equipment tested was significantly less than nameplate ratings, ranging from 14-36% of ratings.
2) The radiant portion of total heat gain ranged from 11-57%, depending on the equipment.
3) Nameplate power ratings should not be used for cooling load calculations as they tend to overestimate loads.
The demand of power is increasing exponentially results in installation of new stations whereas the sources of water are depreciating acutely. In future there may be a situation in which water sources may not cope up with this requirement.
Also the serious concerns of the regulatory authorities regarding usage of natural resources, definitely the norms will be further be tightened, which will curtail the freedom of usage of water in power plant.
In present scenario land acquisition is one of the toughest hurdles in plant installations which can be averted by locating stations in water scarce regions, by employing air cooled system which eliminates dependencies on water for CW.
Although dry cooling systems are costly technologies on techno-economic considerations, but foreseeing the future it is the need of hour to employ dry cooling system which offers possible solution for power plant installation eliminating the above mentioned challenges.
