Abstract
Measuring devices and measuring method focusing on the exit flue gas temperature for a 660-MW ultra-supercritical boiler were studied and applied. Based on the concrete outlet structure of a 660-MW power plant boiler furnace, the design of the structure and the special thermocouples for high-temperature flue gas temperature measurement were carried out, and a real-time continuous measurement method of the large utility boiler’s high-temperature flue gas temperature was achieved. This method revises the underestimated measurement caused by the cold-wall radiation. The flue gas temperature variation with the change of flue gas flow has been analyzed according to the research results. The real-time continuous measurement of high-temperature flue gas temperature of large power station boiler could verify the validity of design data and is also an important basis for operation monitoring, which provides the criterion for the optimization of boiler combustion and the life assessment of the boiler tubes.
