A Study of Combustion Management by Flame Image Monitoring for Pulverized Coal Firing Boilers of Thermal Power Plant

The flame image processing and it's analysis system bas been developed for optimal coal firing of thermal power plant, especially for reducing NOx and safe operation. We aimed at gaining the relationship between burner flame image, emissions of NOx and unburned carbon in furnace by utilizing t'1e flame image processing methods. And the relationship determines quantitatively the conditions of combustion on the individual burners. The test was conducted on Samchonpo thermal power plant #4 unit of 560MW which bas 24 burners. The system simplified the burner adjustment works in accordance with the real time trending of flame behavior like NOx profiles and unburned carbon profiles for individual burners.
