Fraction of heat radiated
Did you know?
WebThe F-factor is also known as the emissivity factor and is basically the fraction of heat generated by the flare flame that is radiated. This figure is calculated for each case and … WebMar 1, 2012 · The fraction of heat radiated is defined as: (1) F = Q r Q where Q = mH with m being the mass flowrate (kg s −1) and H being the net calorific value of the fuel (kJ kg −1 ). Hence if Qr can be measured, or inferred from measurements of incident radiation outside the fire, then F can be determined from experimental data.
