Abstract :
Based on a flame-image processing technology, a real-time combustion-monitoring system with 3-D temperature reconstruction and visualization installed in a coal-fired furnace of a power plant was reported. A dozen of flame detectors with charge-coupled-device cameras were mounted along the height of the furnace to capture multiple digital flame images. A radiation energy signal (RES) was obtained from the flame images according to Wien´s law of radiation. A series of in situ experiments have been done, and the results showed that the flame temperature distribution and the RES are sensitive to change in the combustion of the boiler and can be used to improve the combustion control in practical application.
