Continuous measurement of dust concentrations in wet gas applications

Extractive dust measurement for wet gas applications, blast furnaces, and fine particulate monitoring

DURAG

When process conditions are not suitable for in situ dust measurement, an extractive dust monitoring system provides a reliable alternative. This is particularly beneficial for wet gas applications or when continuous access to the analyzer for inspection and maintenance is required.

For continuous dust monitoring in wet gas applications, DURAG offers an extractive system that uses an isokinetic sampling probe to continuously extract a representative gas sample. The dust concentration is then measured using a light scattering monitor.

For blast furnace applications, DURAG also offers a dedicated analyzer based on beta attenuation technology for accurate dust concentration measurements. This measurement principle is equally well suited for ambient fine particulate (PM) monitoring.

• Continuous dust monitoring in wet gas applications

• Representative sampling using an isokinetic probe

• Choice of light scattering or beta attenuation measurement technology

• Option for laboratory analysis of dust composition and heavy metals

• Analyzer remains easily accessible outside the process for inspection and maintenance
