[0002] At present, a steam generator, also known as a steam heat source machine (commonly known as a boiler), is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. For a steam generator that uses fuel, flue gas is usually generated during its operation, and the flue gas will have a certain temperature. In traditional steam generator technologies, a heat exchange structure is usually provided on the exhaust pipeline of the steam generator to absorb the heat in the flue gas. However, in related technologies, the heat exchange structure provided on the exhaust pipeline is relatively simple as a whole, and only heat exchange plates are simply provided for heat exchange, resulting in poor heat exchange effect, and the speed of flue gas discharge will be relatively fast, and a large amount of heat energy in the flue gas will be directly discharged, thus wasting a large amount of heat energy.
