The convection pass of a boiler is characterized by the mode of energy transfer from the hot flue gas to water or steam, which is primarily via convective heat transfer. On waste-to-energy boilers the flue gas temperature (at the entrance to the convection pass) is typically below 625 °C, which makes it possible to put heating surfaces inside
