[0002] A boiler is an energy conversion device primarily used to convert the chemical or electrical energy in the input fuel into thermal energy, thereby generating steam, high-temperature water, or an organic heat carrier with specific parameters. The boiler is the pressurized component that holds water and steam, heating, vaporizing, and separating the water. The furnace is the site where fuel combustion or other heat release occurs, and includes the combustion equipment, combustion chamber, and heat-releasing flue. The boiler and furnace perform the heat transfer process, and the interface between heat release and heat absorption is called the heating surface.
