Gasification burner for an installation for the gasification of fine-grain to powdery solid fuels, which has a gasification reactor, having a first central guide channel (1) for primary oxidising agents, a surrounding annular fuel channel (2) for the fuels which are introduced with a carrier gas, a second annular guide channel (3), surrounding the annular fuel channel (2), for secondary oxidising agent, and with cooling channels (4) and, optionally, at least one annular moderator-gas channel (5). A plurality of gasification burners send their fuel/reactant jet into the gasification reactor. The fuel/reactant jets form, in the gasification reactor, a high- temperature primary reaction zone. A crude gas is drawn off from the gasification reactor. A tubular injection lance (6), which is supplied with oxidising agent, is arranged in the first supply channel. A flow of fine dust and carrier gas can be injected by the injection lance (6) into the core of the fuel/reactant jet. <IMAGE>
