Abstract

A flame image processing and its analysis system were developed for optimal coal firing of thermal power plant, especially for reducing NOx and safe operations. The aim of this study is gaining a relationship between burner flame image, emission of NOx and loss on ignition (LOI) in furnace by utilizing the flame image processing methods. The relationship determines quantitatively the combustion conditions on the individual burners. The system consists of a computer located typically in the control room and several optical receivers installed in the observation ports near the each coal nozzle. Optical receiver signals were connected to a computer via a frame grabber card. The test was conducted on Samchonpo thermal power plant #4 unit (560MW) of KEPCO which has 24 burners. The system simplified the burner adjustments in accordance with the real time trending of flame behavior like NOx profiles and LOI profiles for individual burners. The system monitors the distribution of these key combustion parameters and displays them in bar graphs and trend charts. This enables operators and engineers to make the informed and targeted burner and boiler adjustments.
