ANCR® – Adaptive Non-Catalytic Reduction

System information and characteristics:

This new technology for reducing NOx emissions presents itself as the further development of the well-known SNCR-technique for industrial applications. The system makes use of the ideal reaction temperature range of the flue gas, ranging from 850 °C to 1050 °C.

This System is using static or electrical actuated injection lances to follow the ideal temperature window of the flue gas to ensure a highly effective denitrification. The flue gas temperature distribution is detected by in-situ gas temperature sensors (pyrometers & thermo-couples) which are activating injection lances in the optimum gas temperature window. 

The ANCR® injection lances are designed to use a urea-solution and/or aqueous ammonia (NH4OH) controlling the position and the direction of the spray to achieve the most efficient NOx reduction. This system is capable to adapt itself automatically to changing process parameters like kiln / boiler load  or different fuel characteristics.

Your ANCR® benefits:

  • up to -75% NOx emission reduction
  • lowest NH3 slip
  • reduced reagent consumption (lower OPEX)
  • cost-effective CAPEX
