1. A method for using a high-temperature fluid in a transporting pipeline to heat a heat-receiving fluid, comprising:
a) providing a heat exchange apparatus, the heat exchange apparatus comprising a heat exchange body located completely within the transporting pipeline, and a heat-receiving fluid inlet pipeline, a heat-receiving fluid outlet pipeline, an auxiliary fluid inlet pipeline and an auxiliary fluid outlet pipeline, which all extend out of a casing of the transporting pipeline; the heat exchange body comprises a heat exchange cavity enclosed by a heat exchange panel, and a heat-receiving fluid coil is installed in the heat exchange cavity;
wherein an installation hole is provided in the casing of the transporting pipeline, the heat exchange body of the heat exchange apparatus is inserted into the interior of the transporting pipeline through the installation hole, a gap between the heat exchange apparatus and the installation hole is sealed using a sealing refractory material, and a supporting structure is further included outside the transporting pipeline for the purpose of supporting the heat exchange apparatus, and
b) providing a heat-receiving fluid and an auxiliary fluid, wherein the heat-receiving fluid flows in the heat-receiving fluid coil, the auxiliary fluid flows or is stationary in the heat exchange cavity, and the heat-receiving fluid is heated by the high-temperature fluid through heat conduction by the auxiliary fluid and heat radiation by the heat exchange panel.
