  • Patent number: 9822003
    Abstract: A process and an apparatus for molten slag gasification of solid fuels in a molten slag gasifier with increased output, an increased range of solid fuels that can be used and improved gas quality. The process is conducted such that, by means of a molten slag gasifier comprising a feed of the coarse-grained solid fuels and comprising a gas takeoff, both at the head of the molten slag gasifier, comprising a slag bath and comprising a slag bath takeoff at the bottom of the molten slag gasifier, comprising a feed for first gasifying means by means of gasifying means nozzles above the slag bath, comprising a filling of the fixed bed above the slag bath, in addition to the first gasifying means a second gasifying means are injected by way of at least one gasifying means nozzle that reaches into the upper region of the fixed bed.
