The combustion monitoring system in utility boilers generally consists of equipment for analyzing O{sub 2}, NO{sub x} and dust in flue gas at the boiler exit. The burner flame diagnostic system developed in this research is comprised of optical probes, optical fibers connecting the burners to a multispectrometer through an optical scanner for multiple burners of the boiler and computer for evaluating flame behavior, so as to serve precise spectroscopic analysis. This research began with a small size test furnace in order to derive combustion evaluation indices, thus successfully leading to theoretical expression in application to a large scale utility boiler. A ploto-type system was mounted on a 350 MW boiler with test result that clearly demonstrate this system to be effective for precise evaluation of individual burners of the boiler.
