Abstract
The present invention discloses a high-temperature fluid transporting pipeline with a heat exchange apparatus installed therein, a suitable heat exchange apparatus and a heat exchange method, wherein heat contained in a high-temperature fluid can be recovered during the transportation thereof. The heat exchange apparatus comprises a heat exchange body inserted into the high-temperature fluid transporting pipeline, and a heat-receiving fluid coil installed therein. The method of heat exchange is that the high-temperature fluid heats an auxiliary fluid in a heat exchange cavity via a heat exchange panel of the heat exchange body in contact therewith, and the heated auxiliary fluid then conducts the heat to a heat-receiving fluid in the heat-receiving fluid coil. As an example, the high-temperature fluid is flue gas generated by combustion, the heat exchange apparatus of the present invention is inserted into a flue gas transporting pipeline, the auxiliary fluid is 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 heat-receiving fluid coil.
