Particulate CEM for wet gas streams

QAL 182 WS

QAL1 approved ProScatter™ particulate CEM for the extractive sampling and measurement of particulate in saturated wet gas streams

Continuous Particulate Monitoring for saturated wet stack applications typically found after wet scrubbers, wet electrostatic precipitators and wet flue gas desulphurisation plant

QAL1 certified against EN 15267-3 to meet EN 14181 and other International standards

  • Extractive sampling system configurable for fixed velocity or isokinetic variable flow rate sampling
  • Continuous Particulate Monitoring for saturated wet stack applications typically found after wet FGDs or filtration systems that produce a wet/condensing flue gas (wet ESPs/scrubbers)
  • Meets QAL1 and other International standards
  • Heated sample lines to maintain sample temperature and prevent the formation of condensation
  • Forward Scatter measurement technique with automatic zero and span (upscale) checks
  • Easy to use intuitive multi-lingual menu with large display for improved user interface complete with on-board diagnostics and multiple analogue and digital communication outputs
  • Small sample chamber and use of advanced polymers – prevents particulate adhesion, condensation and crystal formation. Reduced maintenance for the end user
Stacks with saturated wet flue gas, typically after wet flue gas desulphurisation plant, wet collectors, etc
Typical Applications:
  • Power Generation Plant eg Coal/Biomass
  • Incineration
  • Metals eg Steel/Aluminium
  • Minerals eg Cement/Gypsum
  • Chemicals eg Detergent / Carbon Black
  • Fertiliser
  • Pulp and Paper
