prediction of sox–nox emission from a coal-fired cfb power

Prediction of SOx–NOx emission from a coal-fired CFB power

Firstly, there are limited studies centered on SOx emission prediction using machine learning for a coal-fired CFB boiler. The closest study in the literature is the ANN treatment of SO 2 emission using 45 input-output data pairs ( Krzywanski and Nowak, 2016 ).

Burner optimisation for NOx - IEA Clean Coal Centre

Jan 20, 2018 · Burner optimisation is usually the first method used to control NOx formation. Optimisation is achieved by modifying boiler-operating conditions. Excess air control, boiler fine tuning and balancing the fuel and air flow to the various burners are in use and continue to be investigated to achieve minimum NOx formation in the burner.
