SCR = Selective Catalytic Reduction for power plants and stationary diesel
System information:
We supply catalysts either in honeycomb- or platen design for different applications as high-dust SCR or tail-end SCR. The catalyst enables the reaction of the reagent 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 reagent in the flue gas, the agent is injected via an ammonia injection grid (AIG). 2 AIG-Technologies:
- liquid direct injection
- gaseous injection Systems
SCR Performance: NOx Emission reduction up to 95%, NH3 slip below 5mg/Nm³
Apart from the reagent supply, MAL DeNOx Systems Environmental Technology provides various types of ammonia vaporizers, dilution air heater and seal air fans as well as ammonia flow control units (AFCU). With the help of these systems, outstanding reduction rates and a low ammonia slip can be achieved.
MAL DeNOx Systems Environmental Technology provides turnkey systems specially developed for power plants and stationary diesel engines.
As a reactant, aqueous ammonia and urea solution (solution of urea granular) can be used. Our product range includes the following plant components:
- SCR Catalyst reactor housing
- Ammonia unloading equipment
- Reagent storage tanks
- Processing skids (AFCU)
- Mixing units
- Feed pumps
- Ammonia-Evaporators
- Injection lances or injection grids (AIG)
