Neundorfer is the only precipitator company that produces its own flue gas conditioning systems using a whole system approach to understanding our customers’ needs and presenting alternative solutions. Neundorfer provides flue gas conditioning systems using SO3 or NH3 conditioning agents to improve dust resistivity and optimize electrostatic precipitator performance. The flue gas conditioning control system is integrated with the customer’s choice of programmable logic controller (PLC) and the Neundorfer Precipitator Optimization System (POS) to automatically fine-tune feed rates in order to:
- Use fuel switching or blending as part of an SO2 reduction strategy
- Improve precipitator performance and reliability, especially when changing fuels
- Reduce outlet emissions by improving dust collection and increasing efficiency through modified resistivity
- Provide optimized control algorithms to deliver just the right amount of conditioning agent required based on process and fuel changes
SO3 Conditioning
The addition of SO3 as a flue gas conditioning agent is necessary to achieve optimal dust resistivity and electrostatic precipitator performance when burning low sulfur fuels.

NH3 Conditioning
Ammonia (NH3) reacts in flue gas with SO3 and (less so) with SO2 to increase dust resistivity and enhance precipitator performance in order to:
- Enhance compliance by reducing re-entrainment potential and emissions
- Reduce energy and feedstock consumption for improved profitability
- Neundorfer can assist as well with regulatory issues that surround the use and reactivity of NH3 for flue gas conditioning.
