<p>The invention relates to a process and a device for fixed-bed pressure gasification of solid fuels having an increased performance and also a widened usage spectrum of solid fuels. For this purpose, the process is conducted in such a manner that, using a fixed-bed pressure gasifier with a feed of the coarse-grain solid fuels and with a gas take off, both at the top of the fixed-bed pressure gasifier, with a rotary grid and with ash discharge at the bottom of the fixed-bed pressure gasifier, with an adjustable feed for first gasification agent for a non-slagging gasification using the rotary grid of the fixed-bed pressure gasifier, wherein critical minimum values for the steam-oxygen ratio can be set, having a heap of the fixed bed above the rotary grid, in addition to the first gasification agents fed using the rotary grid, second gasification agents for a slagging gasification are injected via at least one gasification agent nozzle extending into the upper region of the fixed-bed heap.</p> |
