The invention discloses a subsequent flue gas system combined arrangement structure for six outlets of a dust remover and induced draft fans in two rows. The structure comprises double rows of the induced draft fans connected with the six outlets of the dust remover, desulfurization absorption towers correspondingly connected with the double rows of induced draft fans, and chimneys connected with the desulfurization absorption towers, wherein the center lines of the double rows of induced draft fans, the desulfurization absorption towers and the chimneys connected in sequence are located on the same plane; the desulfurization absorption towers and the chimneys are vertically arranged side by side closely; the double rows of induced draft fans are transversely arranged at the outer sides of the desulfurization absorption towers side by side; the desulfurization absorption towers are arranged between the double rows of induced draft fans and the chimneys; and outlets of the double rows of induced draft fans are all aligned to the desulfurization absorption towers. All pieces of equipment behind the dust remover are arranged in a linear space in a combined manner, so that the equipment arrangement is more compact, the floor occupancy is reduced, and the flue connecting length is shortened.
