Particulate Matter Emission Monitoring Solution

Figure 1 - Mainstream Technical Roadmap

● SCR denitrification technology: denitrification efficiency ≥90%

● High-efficiency dust removal technology: dust removal efficiency ≥99.8%

● High-efficiency desulfurization with synergistic mercury control: desulfurization efficiency≥99%, mercury removal ≥80%

● Wet electrostatic deep removal: PM2.5 removal efficiency ≥90%

1. Low-concentration, high-humidity operating conditions impose higher requirements on instruments; existing smoke/dust monitors struggle to meet the requirements.
2. Differences in particle size and color of dust particulate matter cause conventional opticalinstruments to be unable to accurately measure on-site concentrations.
3. Large weighing comparison errors and slow value output for particulate matter, lack of real-timedetection means on-site, making effective supervision difficult.

The Dust Concentration Measuring Instrument (Ultra-Low) adopts the forward scattering method for measurement. Through full-path high-temperature extraction and isokinetic sampling, it avoids the influence of high-humidity water vapor on measurement. It can be used for continuous online monitoring of particulate matter under high-humidity, low-concentration conditions, and is particularly suitable for measuring low-concentration dust in flue gas after wet desulfurization and wet dust removal in coal-fired boilers.
