Medidor de polvo para humos por debajo del punto de rocío

QAL 182 WS

Medidor de polvo por difracción con certificado QAL1 para el monitoreo de polvo extractivo en humos húmedos saturados.

Monitoreo continuo de partículas para aplicaciones de chimeneas húmedas saturadas, que generalmente se encuentran después de depuradores húmedos, precipitadores electrostáticos húmedos y sistemas de desulfuración de gases de combustión húmedos.

Certificado QAL1 según EN 15267-3 (prueba de idoneidad alemana) para cumplir con EN 14181 y otras normas internacionales

  • 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
