Two mechanisms, aerosol indirect heating and radiative heating, are used as the first step of aerosol desolvation, for heating the aerosol.
Unfortunately, the equivalence between electrical heating and radiative heating cannot be obtained on the obvious way.
Considering the detailed furnace geometric parameters and the multi-zone heating manner, the radiative heat flux is calculated by a simplified zone method.
Comparisons are drawn between heat and radiative formulations.
The change of particle temperature during devolatilization is determined from the energy balance of particles governed by convective, latent heat and radiative heat transfer as follows [17, 18].
Thermal radiative heat flux reduces the heat transfer rate but the opposite tendency is seen for mass transfer rate.
In the absence of any medium, radiative heat transfer is the dominant heat transfer mode.
They had a machine that emitted radiative heat at 1,800 degrees Fahrenheit without convective heat, and they started placing different flammable materials in front of it.
The effects of relating parameters on the directional behavior of radiative heating and the heating efficiency are analyzed.
Also, the level of dilution of the combustion air influences significantly the rate of radiative heat transfer and the ratio of radiative to convective heat transfer rate.
