摘要（英）：

The invention relates to a device using a flue gas waste heat heating cold-air blowing system and a use method of the device. The device comprises boiler tail high-temperature flue gas, an air preheating assembly, a flue gas waste heat heating cold-air blowing assembly, a control system assembly and a dust remover. The boiler tail high-temperature flue gas is connected with the air preheating assembly through a boiler tail flue. The air preheating assembly is connected with the flue gas waste heat heating cold-air blowing assembly through a flue gas transmission pipeline. The flue gas waste heat heating cold-air blowing assembly is connected with the dust remover through a flue gas recycle pipe. The control system assembly is connected with the air preheating assembly and the flue gas waste heat heating cold-air blowing assembly. The flue gas waste heat heating cold-air blowing assembly is further connected with the air preheating assembly through an air preheating air supply pipeline. The device and the use method have the beneficial effects of being simple in structure, reasonable in design, convenient to operate, reliable in performance, high in automation degree, low in daily maintenance and overhaul cost, capable of saving energy, environment-friendly, and the like.
