DURAG D-R 320

General Details

Scattered Light Monitor

The new scatter light dust monitor detects low to medium dust concentrations in dry flue and process gas.

Continuous emission Monitoring, e.g:

  • On incineration plants generally
  • On plants according to IED 2010 / 75 / EC LCPD / 13. BlmschV
  • On waste, hazardous waste and sewage sludge incineration plants
  • On cement manufacturing plants
  • On power plants with gas, oil, coal or co-firing
  • On plants for the incineration of biomass

 

Overview

 

  • Continuous measurement of dust concentration
  • Easy installation on a standard flange
  • Easy startup without adjustment
  • Automatic background light compensation without light trap
  • Convenient operation, remote access possible
  • Automatic control functions
  • Integrated purge air regulation and purge air control
  • Long service intervals
  • Compliant with EN 15267
  • Data transfer via Modbus compliant with VDI 4201-3
