In a combustion system to transfer heat at high temperature in heaters comprising a radiant box where the fuel is fired, the combustion air, available at ambient temperature or after preheating using an external source of heat or the sensible heat of the flue gas of the heater itself, is sent to one or more external adiabatic burners where a partial combustion is performed before said combustion air is introduced into the radiant box to be mixed with the fuel. |
