description The invention discloses a flue gas waste heat recovery system of a large flue of a sintering machine. The waste heat recovery system comprises a large flue near the tail of the sintering machine, wherein the large flue is internally provided with a valve, a bypass flue of the large flue is arranged near the large flue, the bypass flue is internally provided with a heat exchanger, the bypass flue between the heat exchanger and the large flue is provided with control valves, and the heat exchanger is provided with a water inlet pipe and a water outlet steam pipe. According to the invention, by controlling the amount of the flue gas of the large flue and the bypass flue, the flue gas heat amount of the large flue of the sintering machine can be adequately recovered, the lowest temperature of the flue gas of the large flue can be ensured as well, so that dew formation of flue gas can be avoided. The waste heat recovery system disclosed by the invention has the advantages of simple structure and controlling, econo
