Technical Field

[0001] The utility model relates to the technical field of steam boilers, in particular to a steam boiler based on water circulation. Background Art

[0002] A steam boiler is a device that produces steam by heating water. These devices are commonly used in heating systems, industrial production, and power generation. Steam boilers usually consist of a fuel supply system, a burner, a boiler body (including a kettle and pipes), and a control system. When water is heated to produce steam, the steam is used in various applications, such as driving machinery or providing heat energy.

[0003] The condensed water produced by steam usually has residual temperature. When the steam cools and becomes liquid, it releases heat, which means that the condensed water still has a certain residual temperature. The condensed water produced by the recovered steam and the added water are not mixed and directly enter the steam boiler, which will affect the heating, which may cause uneven temperature and reduce heating efficiency.
