Medidor de polvo para humos por debajo del punto de rocío

STACK 181 WS

Medidor de polvo por difracción óptica (ProScatter™) que cumple con US-EPA PS11 para la extracción y medición de polvo en humos saturados

  • 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)
  • US EPA PS11 capable as a PM–CPMS or PM–CEMS
  • Extractive sampling system configurable for fixed velocity or isokinetic variable flow rate sampling
  • Heated sample lines to maintain sample temperature and prevent the formation of condensation
  • Forward Scatter measurement technique with automatic zero and span (upscale) checks that fully challenge the system to satisfy daily drift check requirements
  • Easy to use intuitive multi-lingual text driven menu and display for improved user interface complete with on-board data logging for increased level of security of data
  • 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
