The invention discloses a high-temperature fluid conveying pipeline internally provided with heat exchange equipment, the applicable heat exchange equipment and a heat exchange method. Heat in high-temperature fluid can be recycled in the conveying process of the high-temperature fluid. The heat exchange equipment comprises a heat exchange body inserted into the high-temperature fluid conveying pipeline and a heated fluid coil pipe installed in the heat exchange body. According to the heat exchange method, the high-temperature fluid heats the auxiliary fluid in a heat exchange containing cavity through a heat exchange panel of the heat exchange body making contact with the high-temperature fluid, and the heated auxiliary fluid conducts heat to heated fluid in the heated fluid coil pipe. Asan example, the high-temperature fluid is flue gas generated after combustion, the heat exchange equipment is inserted into a flue gas conveying pipeline, the auxiliary fluid is inert gas such as air, and the air indirectly heated by the high-temperature flue gas conducts heat to fuel and / or oxygen-enriched gas (serving as an oxidizing agent / combustion improver) flowing in the heated fluid coil pipe.
Description
technical field [0001] The invention relates to the field of high-temperature fluid heat recovery, especially recovering heat from hot flue gas of a glass melting furnace for heating fuel and / or oxygen-enriched gas. Background technique [0002] Protecting the environment, saving energy, land and costs are the concerns of modern industrial development. Various technological processes such as metallurgy, glass melting, and chemical production require a large amount of energy, and at the same time produce products or by-products that contain a large amount of heat energy. For example, the flue gas or water vapor produced during the combustion process, and the synthesis gas and water vapor produced by the reforming reaction of natural gas are all high-temperature fluids that contain a large amount of heat energy. If the heat energy in these high-temperature fluids cannot be recovered, it will cause a great waste of energy and production efficiency. [0003] Taking the product...
