AET SNCR DeNOx System

Increasingly stricter legal requirements for NOx emissions, as well increased costs in connection with discharge, has led to an increasing number of companies investing in NOx reduction systems.

The SNCR deNOx system specifically developed by AET incorporates a number of well-proven solution which together ensure a highly reliable system with a very long lifespan and with a minimum of maintenance and operating downtime.

 

Features:

  • Flexible for both urea and ammonia with a simple rebuild ensures streamlined production which needs few spare parts.
  • The system is flexible and can be used without rebuild for changed fuel properties or performance.
  • Compact design ensures a fast overview of the instrumental read-out, which decreases the risk of operating errors.
  • Heaters in urea tank are mounted in horizontal "pocket" to allow heaters to be replaced during operation.
  • Double filters with differential pressure monitoring enables filters to be cleaned or replaced during operation
  • Urea pump with magnetic coupling, i.e. without shaft seal, eliminates the risk of leaks at the shaft.
  • All conduits are stainless which prevents corrosion.
  • Quick couplings on lance and hose connections resulting in fast removal/replacement.
  • Simple dismantling of spray nozzle making it quick and easy to clean lance connectors.

To make sure that the chemical reaction takes place optimally in the furnace room, the lances must have the correct location in the furnace room. This applies to both temperature as well as the allocation of urea over the whole cross section of the furnace room. To ensure this, AET utilises the company’s substantial experience of designing biomass-fired boilers for a wide range of different fuels. This also ensures that the use of reducing agents and deonat is minimised thus resulting in lower operating costs as well as reduced impact on the environment.

 

In summary: Well-proven quality throughout the plant design.
