Sistema de monitoreo de emisiones electrodinámico certificado

QAL 991

Instrumento de medición de polvo certificado QAL1 para un monitoreo preciso de emisiones en bajas concentraciones provenientes de procesos industriales con filtros de mangas y filtros de cartucho.

El QAL 991 es un sistema de control continuo de emisiones, certificado para polvo, diseñado para cumplir y superar la norma CEN EN 14181 / EN 13284-2. Particularmente adecuado para monitorear las emisiones de procesos industriales regulados por la Directiva europea sobre incineración de residuos (WID) y la Directiva sobre grandes centrales eléctricas de combustión (LCPD), el QAL 991 también se prueba en otros procesos industriales controlados con filtros de bolsa de alto rendimiento. El instrumento cuenta con la certificación QAL1 especificada en EN 15267-3, tanto bajo MCERTS como 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)
