The primary mode of heat transfer in water-cooled walls is radiation, accounting for over 80%. The heat transfer process consists of three steps:

Radiative heat transfer: In the furnace, high-temperature flames and flue gases (1000–1800℃) directly radiate heat in the form of electromagnetic waves to the outer surface of the water-cooled wall tubes.
Heat conduction: Heat is conducted through the metal pipe wall from the outer wall to the inner wall.
Convection heat transfer: Water or a water-steam mixture inside the tube absorbs heat through convection.
