Secondary DeNOx Systems (SNCR and SCR)
The majority of combustion processes generate nitrogen oxides (NOx), which are subject to regulation under national legislation and particularly in accordance with BREF/BAT standards. For our customers, we implement secondary measures to reduce NOx concentrations in flue gases through Selective Non-Catalytic Reduction (SNCR) and Selective Catalytic Reduction (SCR).
We implement SNCR and SCR technologies across all combustion systems (sources of harmful emissions), from small CHP units to large granulation, fluidized bed, and grate boilers, accommodating all types of fuels (solid, liquid, and gaseous). We offer a complete turnkey solution, managing everything from the initial design to the successful completion of guarantee tests. Alternatively, we can supply individual technological components tailored to the customer’s specific requirements.
The steps and scope of our work include:
- Detailed analysis of the combustion system in question
- Advanced process modelling using CFD analysis
- Basic design of the secondary DeNOx measures
- Operational testing of SNCR technology with mobile testing equipment to identify the best achievable results, taking into account both investment and operating costs
- Detailed project implementation documentation
- Delivery of all equipment and technological components
- Preparation of operational and technical documentation
- Commissioning and optimisation of the technology’s operation
- Comprehensive testing and guarantee measurements
- Training the customer’s staff in the operation and maintenance of the equipment
- Warranty and post-warranty service
