The utility model relates to a coal-fired boiler high-temperature zone smoke temperature testing device based on short-term off-line measured data. The coal-fired boiler high-temperature zone smoke temperature testing device comprises a boiler, a platen superheater, a high-temperature superheater, a high-temperature reheater, a low-temperature superheater, a low-temperature reheater, a coal economizer, a temporary thermocouple group, a furnace top small chamber, a ceiling superheater, a wall superheater and a data acquisition instrument. Wherein the furnace top small chamber is positioned at the top of the horizontal flue, the ceiling superheater is positioned at the upper parts of the hearth and the horizontal flue, and the wall enclosure superheater is positioned at the periphery of thehorizontal flue. The utility model has the beneficial effects that the cost is low, the defect that the thermocouple can not be used for a long time in a high-temperature environment is overcome, onlyone batch of thermocouple
