A method for generating synthesis gas by gasification of solid or liquid carbonaceous fuels with an oxygen-containing oxidizing agent in a reactor, wherein the synthesis gas is removed from the reactor overhead and the mineral ash/slag droplets produced during the reaction are removed from the reactor downwards in the direction of gravity, is intended to make it possible to use a markedly less expensive fire-tube boiler for heat removal instead of a radiant boiler. This is achieved in that the synthesis gas is passed uncooled over a hot gas filter (2) and subsequently for cooling through a fire-tube boiler (3), wherein the ash/slag particles separated off at the hot gas filter (2) are recirculated in the direction of gravity back to the gasification reactor (2).
