A process for the generation of a syngas in an entrained-flow gasification process includes a solid, carbon-containing fuel which is introduced via burners into a reactor which also supplies the oxygen for gasification. The fuel is introduced on a burner level where the burners are arranged concentrically around the reaction chamber or in the head area. The syngas obtained is discharged from the reaction chamber via a discharge nozzle, so that the syngas is passed into a collecting chamber for cooling by addition of low-temperature gaseous, vaporous or liquid cooling agents. A quench chamber is provided between the reactor and the collecting chamber. Additional burner levels are in the quench chamber via which a fuel material of renewable fuels or biofuels is introduced into the syngas, so that the heat enthalpy of the syngas can be utilized for the endothermic gasification reaction of the biological raw material. An apparatus for this generation of synthesis gas includes several burner levels, the renewable fuel being supplied to the gasification chamber with or without water vapor or oxygen and the enthalpy of the hot syngas being utilized for the gasification of the renewable fuel.
