Flame Image Analysis Systems for Combustion Conditions Monitoring

Flame Image Analysis Systems for Combustion Conditions Monitoring

The flame image processing and analysis systems have been developed for optimal coal firing of thermal power plant, especially for low NOx and safe operation. We aimed at gaining the relationship between burner flame image and emissions of NOx and unburned carbon in furnace by utilizing the flame image processing methods, through which this system quantitatively determines the conditions of combustion on the individual burners. For the first step of development, its possibility test was undertaken with bench furnace. The test proceeded to the second step with pilot furnace, thraufh which the system was observed to be effective for evaluating the combustion conditions monitoring and burner maintenance.
