Frequently Asked Questions
What is the ideal droplet size for dust suppression?
For respirable dust (PM10), droplets of 10-50μm are most effective. Ultrasonic nozzles (1-10μm) are best for dry fog applications.
How does dry fog differ from conventional misting?
Dry fog produces ultra-fine droplets (1-10μm) that capture dust without wetting materials. Conventional misting uses larger droplets that can cause material wetting.
What droplet size is most effective for coal dust?
For coal dust (10–100μm), droplets of 50–200μm are optimal. Larger droplets capture coarse particles, while fine mist (10–50μm) captures respirable dust.
Can dry fog nozzles be used outdoors?
Yes, but wind can affect dispersion. For outdoor use, install wind shields or use higher pressure to increase droplet velocity.
How do I prevent nozzle freezing in winter?
Use heated enclosures, trace heating, or air‑assisted nozzles that purge water after use. Alternatively, use dry fog systems that use minimal water.
What is the typical water pressure for dust suppression?
For full cone nozzles, 2–7 bar. For air atomizing, 0.7–4 bar liquid plus 2–6 bar air. Ultrasonic nozzles operate at low pressure (<3 bar).
