摘要： The present invention discloses a transporting pipeline 25 for a high-temperature fluid with a heat exchange apparatus installed therein, a suitable heat exchange apparatus and a heat exchange method, wherein heat contained in the high-temperature fluid can be recovered during the transportation thereof, the heat exchange apparatus comprising a heat exchange body 1 inserted into the transporting pipeline 25, and a coil 8 for a heat-receiving fluid installed therein, whereby the high-temperature fluid heats an auxiliary fluid in a heat exchange cavity 7 via a heat exchange panel 6 of the heat exchange body 1 in contact therewith, and the heated auxiliary fluid then conducts the heat to the heat-receiving fluid in the coil 8, whereby the high-temperature fluid may be flue gas generated by combustion, the heat exchange apparatus of the present invention being inserted into a flue gas transporting pipeline 25, the auxiliary fluid may be an inert gas such as air, and the air heated indirectly by the high-temperature flue gas conducts heat to fuel and/or oxygen-enriched gas (serving as an oxidant/combustion aid) flowing in the coil 8.
