Membrane wall is a special type of boiler heating surface, primarily designed to absorb and convert heat within the boiler.
The membrane wall is composed of a series of membranes, with air or water sandwiched between them, forming a thin air or water film. When high-temperature flue gas passes through these membranes, heat is transferred from the flue gas to the air or water, causing their temperature to rise, thereby achieving heat absorption and conversion.
Membrane walls offer advantages such as compact structure, excellent heat transfer, and ease of cleaning and maintenance. Additionally, the manufacturing and installation of membrane walls must be conducted according to specific circumstances to ensure their safe and reliable operation.
In summary, the membrane wall is one of the critical heating surfaces in boilers, serving to absorb and convert heat within the boiler, thereby enhancing the overall efficiency of the power system.
