The invention relates to a coal-fired boiler high-temperature area smoke temperature testing device based on short-term offline measured data. The coal-fired boiler high-temperature area 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,temporary thermocouple sets, a furnace top chamber, a ceiling superheater, a wall enclosure superheater and a data collector, wherein the furnace top chamber is located on the top of a horizontal flue, the ceiling superheater is located on the upper portion of a combustion chamber and the upper portion of the horizontal flue, and the wall enclosure superheater is located around the horizontal flue. The coal-fired boiler high-temperature area smoke temperature testing device has the beneficial effects that the cost is low, the defect that thermocouples cannot be used for a long time in a high-temperature environment i
