what are the heat transfer mode in a boiler system?
Most boilers utilize radiation, conduction and convection as the modes of heat transfer. Radiation from the burner flame, conduction and convection from the hot gases to heat the boiler tubes and conduction and convection to heat and boil the water. If there is a boiler feed water or combustion preheater, they would utilize conduction and convection.
