I am suppose to calculate the overall heat Flux through a modified Boiler pipe. when we calculate the heat flux we only consider energy transfer through convection? My question is that do we include radiation (in terms of internal emissivity ) while calculating over all heat Flux through a boiler pipe with Flue gas inside the boiler and tube surface temperature as 457 K.
