Specifically, the surface of the flue 3 facing the tower body 1 is attached to the outer peripheral surface of the tower body 1, and the plurality of flue gas outlets 32 are formed in the surface of the flue 3 facing the tower body 1. For example, the flue comprises an inner plate body and an outer plate body, the inner plate body is attached to the outer circumferential surface of the tower body 1, and the flue gas outlet 32 is formed in the inner plate body.
In some embodiments, the flue 3 comprises a plurality of sub-flues, each sub-flue having a flue gas inlet 31 and a flue gas outlet 32.
