The wrong APCD leads to frequent shutdowns and failed emission tests. Start with particle and gas characterization.
Key points
- Cyclone separators for larger particulates and as pre-cleaners.
- Baghouse filters for fine dust with controlled temperature and moisture.
- Wet scrubbers for certain gases/fumes (with wastewater handling).
- ESPs for large flows and consistent particulate profiles.
- Maintenance planning: pressure drop, cleaning cycles, and spares.
Pair APCD selection with correct stack design and monitoring points for reliable testing.
