Hi Olivier,

Assuming that you are interested in the heat transfer to the furnace walls then you can simply report total and radiant heat to walls (Report >Fluxes). In a furnace, the bulk temp will be some 1500 degC reaching peaks of some 1800-1900 degC, therefore the majority (>70%) of heat release will be radiant.
