Description

Technical Field

[0002] A steam generator, also known as a steam heat source or boiler, is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam. The steam generator works by using the heat generated by a reactor power unit or fuel combustion to boil water, thereby producing steam.

[0003] Steam generators can be categorized by fuel type, including electromagnetic steam generators, electric steam generators, oil-fired steam generators, gas-fired steam generators, and biomass steam generators. They are widely used in various industries, such as food processing, textile printing and dyeing, chemical production, building materials production, power generation auxiliary equipment, and medical disinfection. In these applications, the stable steam provided by steam generators ensures smooth operation and guarantees product quality and safety.

[0004] Current steam generators generally use electric heating tubes or heating wires to heat water to produce steam. While this type of steam generator has a relatively simple structure and can essentially achieve the function of heating water to produce steam, it has a slow heating speed, low heating efficiency, average product quality, and insufficient steam production, resulting in low performance of steam-using devices, inconvenience for users, and a poor user experience. Furthermore, the large size of the electric heating tubes and heating wires results in a larger steam generator, hindering product miniaturization and failing to meet existing needs.
