| 摘要 |
The invention relates to a process for operating a plant for the gasification of solid fuels, gasification burners being used which have a primary oxygen feed channel coaxial with the burner axis, a surrounding annular fuel feed channel and, surrounding the latter, an annular secondary oxygen feed channel, the fly dust precipitated from the crude gas being introduced into the axis of at least one fuel/reactant jet, being introduced by the latter into the primary reaction zone of the gasification reactor and being fused in this zone. A primary oxygen/secondary oxygen mass ratio of 1:1 to 1:4, preferably 1:1 to 1:3, is intended to be used here. |
