What is a water wall?

A water wall is a set of tubes that contains boiler water and absorbs heat. In boiler systems, water walls are used to improve efficiency and help to manage the heat transfer process. The design typically involves tubes filled with water that are positioned in areas where heat from combustion can be absorbed. This enhances the overall boiler performance by ensuring that more heat is utilized in generating steam, leading to improved energy efficiency. The water inside the tubes is heated directly, allowing it to be transformed into steam further along in the system, which is essential in various industrial applications. This mechanism is vital for maintaining optimal operating conditions in a boiler.
