Technical Description
This invention is an online optical instrument that continuously measures fly ash concentration in industrial stacks, even in the presence of high moisture or droplets. It uses a polarized green laser and multi-angle scattering detection to separate fly ash from water aerosol, enabling accurate, real-time particulate emission monitoring in wet stacks where conventional opacity systems give erroneous readings.
Problems Addressed
- Moisture Interference
- Inaccurate PM Readings
- Wet-Stack Limitations
- CEMS Inefficiency
- High-Velocity Errors
- Sampling/Dilution Errors
Tech Features
- Moisture-Independent Optics
