98-15: The New Wet/Dry Cooling Tower Without Finned Tube Dry Section

NWD uses the multi purpose fill, which is consisted of all wet and wet/dry lanes. During the summer season, NWD can be used as all wet cooling tower by using wet/dry lanes as wet sections, and during plume abatement (winter) season, NWD can be used as wet/dry cooling tower by using wet/dry lanes as dry sections which are acting similar to finned tube dry sections. The design criteria of NWD had been established by the experiment and a prototype NWD was installed to confirm the result of the experiment and no plume was visible at the fan stack exit.
