Boilers are mainly used in industrial production, commercial hot water supply, residential water use and other scenarios. A boiler is mainly composed of a pot and a furnace. The hot water or steam generated by the boiler can directly provide the heat energy needed by industrial production and domestic water.

According to the purpose of the boiler, it can be roughly divided into: domestic boiler (daily water consumption and heating); Industrial boilers (mostly used in textile mills, food factories, clothing factories and other places to provide steam to help production); Power plant boiler (used for power generation in power plants)
