The invention discloses a recovering device for afterheat of garbage incineration furnace, which is implemented to cooperate with the main furnace body and the fume passage connected to the main furnace body; an evaporator, a superheater and an economizer are arranged in the fume passage, wherein a heat exchanger is also arranged in the fume passage; the heat exchanger at the tail of the fume passage recovers the heat energy of the fume at the outlet of a afterheat furnace, so that the temperature of the fume at the outlet of the afterheat furnace decreases and is controlled more efficiently, fume discharge loss of the afterheat furnace is reduced, and the heat efficiency of the afterheat furnace is enhanced; water spray on the fume for lowering temperature is unnecessary, thus saving quantities of water resource; and meanwhile a water spray device independently arranged for lowering temperature is not required, thus simplifying fume processing system technique, improving reliability of the fume processing system and prolonging the service life of the fume processing system equipment. |
