Sistema elettrodinamico certificato di monitoraggio emissioni

QAL 991

Strumento di misurazione polvere certificato QAL1 per un accurato monitoraggio emissioni in basse concentrazioni da processi industriali con filtri a maniche e filtri a cartuccia.

Il QAL 991 è un sistema per il controllo delle emissioni in continuo, certificato per le polveri, progettato per soddisfare e superare lo standard CEN EN 14181 / EN 13284-2. Particolarmente adatto al monitoraggio delle emissioni da processi industriali regolamentati dalla direttiva europea sull’incenerimento dei rifiuti (WID) e dalla direttiva sulle grandi centrali a combustione (LCPD), il QAL 991 è anche collaudato in altri processi industriali controllati con filtri a manica ad alta efficienza. Lo strumento possiede la certificazione QAL1 specificata nella norma EN 15267-3, sia sotto MCERTS che TUV.

  • Robust design unaffected by product build-up on the sensor rod
  • No additional services such as air purge required, providing lower cost of ownership
  • Simple maintenance no requirement for specialist service personnel
  • Complies with standards EN 13284-2, EN 14181 and EN 15267-3 and applications with Emission Limit Values (ELVs) of 7.5 mg/m3 (Incineration) and 15 mg/m3 (co-incineration)
  • Automatic recording of drift checks (zero and span) to satisfy QAL3 requirements
  • Networking of sensor channels and providing multiple inputs for external devices such as temperature, pressure and 02 normalisation
  • Stacks after bag filters, cartridge filters, cyclones, electrostatic precipitators, no filtration
  • Variable velocities within range 5 – 25 m/s (typical bag filter velocity ranges)
  • Non-condensing / dry flue gases
    Typical Applications:

  • Incineration
  • Metals (eg Steel/Aluminium)
  • Minerals (eg Cement/Gypsum)
  • Chemicals (eg Detergent/Carbon Black)
  • Power Generation Plant (eg Coal/Biomass)
