Drift data from a large natural draft brackish water cooling tower and brackish water particulate scrubber
Drift data are presented which were acquired in PEPCO's Chalk Point Unit No. 3 fossil-fuel power plant natural draft cooling tower and Unit No. 3 scrubber stack at Aquasco, Maryland. Source data in the form of droplet size spectra and salt mass emission were acquired via an equal area traverse near the exit plane of the 400 foot tower and at the 420 foot level of the 712 foot stack. Results show that the drift fraction of the tower is within the manufacturer's guarantee when the tower circulating water flow rate is assumed to be the design value (260,000 gpm). Droplet spectra show that at least 83% of the tower drift mass emission is represented in droplets less than 240 micrometers in diameter. Results show further that the sodium mass emission and drift droplet mass median diameter of the stack are comparable to those from the cooling tower.
