Abstract

Taking a large wet cooling tower of a 1 000 MW unit as the research object

a 3D numerical calculation model of the three-zone synergistic efficiency enhancement pattern was established based on partition water distribution

non-equidistant fillings layout and dry-wet hybrid rain zone

and the accuracy of model was validated. Meanwhile

researches were emphatically conducted on the effect of the three-zone synergistic efficiency enhancement pattern on the thermal and resistance performance of the wet cooling tower under variable operating conditions. Results show that the thermal and resistance performance of the three-zone synergistic cooling tower is significantly superior to that of the conventional cooling tower under variable operating conditions. Within the study range of circulating water flow rate

tower inlet water temperature

air dry-bulb temperature and air humidity

after adopting the three-zone synergistic efficiency enhancement pattern

the water temperature drop is increased by 0.63-0.72 K on average

the cooling efficiency is increased by 3.66-4.11 percentage points on average

the Merkel number is increased by 0.16-0.20 on average

and the ventilation rate is increased by 10.54%-10.91% on average.
