Benefit:

• Save NOx and slip compliance

• Reduced spray amount and reduced slip

• NOx and slip limits compliance

• Reduced primary NOx

• Reduced NOx peaks

• Less temperature tilts

• Fast adaptation to coal quality changes

• Better measurement, better control

Features:

• Step 1: Combustion Optimisation for primary NOx reduction
• Step 2: Optimising control of SNCR (Powitec SNCR or 3^rd party) 

• Integration of additional sensors (PiT FluxStylus, PiT Indicator and/or PiT VibraSensor)

• On-line CFD every 15 seconds: 3-D determination of flue gas temperature, mass flow and speed

• Automatic feature selection and extraction (significance ranking)‏ of existing process data

• Automatic model generation (regression, neuronal networks, probabilistic nets, Gray-Box-Models)‏

• Set point integration into the DCS/PCS

• Advanced signal processing on acoustic measurements

• Modular system: Upgradeable to Boiler-Optimiser
