The hot water boiler is a thermal energy supply equipment that meets the national environmental protection requirements. Widely used in food, printing and dyeing, chemical, pharmaceutical and other industries. As a mechanical device, good maintenance can extend the life of the equipment, so be sure to know the name of each part, the name and location of each term in the maintenance.
First, let’s look at the definition of the heating surface of a hot water boiler:
The hot surface of the hot water boiler refers to the interface that absorbs heat from the heat release medium and transmits it to the heat medium, including the convection heating surface and the radiation heating surface.
A heating surface that mainly absorbs heat from a heat release medium by a radiation heat exchange method, and mainly receives a heat receiving surface from a heat release medium by a heat transfer method. Such as water wall tubes, furnaces, etc.
Convective heating surface
A heated surface that absorbs heat from a high-temperature flue gas in a convective heat transfer manner generally refers to a heated surface through which the flue gas passes, such as a flue, a convection tube bundle, and the like.
