    CECO Aarding - Selective Catalytic Reduction (SCR) for NOx Emissions

    As flue gases are combusted in gas turbines and process furnaces, nitrogen oxide (NOx) is formed. Our Selective Catalytic Reduction (SCR) system is a post-combustion NOx control technology, which injects an ammonia (NH3) based reagent into the flue stream to reduce NOx emissions by up to 95%. Our SCR designs are engineered to optimize efficiency, ...

  • Model SCR - Selective Catalytic Reduction for Power Plants and Stationary Diesel

    The catalyst enables the reaction of the reduction agent with the NOx formations of the flue gas already at lower flue gas temperatures (typically 200- 450°C). To ensure a homogeneous distribution of the reductant in the flue gas, the agent is injected via an ammonia injection grid. Apart from the reductant supply, M.A.L. Environmental ...

  • Model SNCR - Selective Non-Catalytic Reduction

    The classic technology for the reduction of NOx emissions is applied within the temperature range of 900°C to 1050°C of the flue gas. Dual compound lances are used to inject aqueous ammonia or urea solution within the ideal flue gas temperature window reducing NOx emissions. The reactant volume is adapted to the load condition and ...

  • Caldyn - NOx-reduction Systems

    Nitrogen oxides that cause pollution of the environment are converted to nitrogen and water by adding a reducing agent (urea solution or ammonia). With the SCR process the reducing agent is injected at comparatively low temperatures and the nitrogen oxides are reduced to molecular nitrogen using a catalyst. With the SNCR process the reducing agent ...

  • Selective Catalytic Reduction System (SCR)

    As with the SNCR process, SCR involves injecting either an ammonia or urea based reducing agent into the flue gas of a combustion source of an industrial source. The main difference with SCR is that a catalyst is used, which accelerates the chemical reaction and allows it to occur at lower temperatures. The potential operating temperature range of ...

  • Selective Non-Catalytic Reduction System (SNCR)

    The SNCR process involves injecting either an ammonia or urea based reducing agent into the flue gas of a industrial combustion source, where an optimum temperature window of between 850°C - 1050°C exists. The purpose of the reducing agent is to enable reduction of the NOx species. The resulting product of the chemical reaction is ...
