HEATING BY RADIATION
   The most common applications adopt the heat transfer by direct contact or by convection. There are cases, however, in which peculiar process characteristics (rapid working cycle, necessity toheat moving objects, impossibility to seal the heating process inside a volume that is closed to the external environment) do not allow to use effectively the heating by conduction or convection.In these cases the most appropriate solution is to adopt a heat transfer by radiation.The heating by radiation allows to heat easily and quickly moving objects. The dimensional and manufacturing characteristics of the heat radiators allow the construction of “open” ovens, normallyinstalled around mobile surfaces (e.g. conveyor belts) inside which it is possible to reach in a short time the desired temperatures without presenting significant heat losses throughout the oveninlet and outlet sections.In addition, if the operational temperature is adequately selected, high specific power densities (higher than those typical of conduction or convection heating), can be obtained.
