By means of a method and a system for heating and partial oxidation of not separately pre-heated, pre-reformed steam/natural gas mixture for an NH3 synthesis gas, whereby energy is supplied to the gas stream (raw synthesis gas), in the direction of flow, after a primary reformer, a solution is to be created, with which soot formation is to be prevented as much as possible, whereby the possibility of the addition of variable amounts, for example of N2 and O2 or mixtures thereof, is also supposed to be possible. This is achieved, according to the method, in that the energy is supplied directly after the primary reformer, by way of at least one pore burner positioned in the gas discharge line of the primary reformer.
