Abstract
The present invention relates to a process and a device for the combustion of sulphur and/or sulphur-containing compounds, via which a sufficient production of SO2-containing gases having a high SO2 concentration is made possible. The combustion preferably proceeds using a combustion gas which has an oxygen fraction at least as high as air, but preferably a higher fraction of oxygen. The process and the device should be suitable, in particular, for providing sulphur dioxide as a source for further production of sulphuric acid or highly concentrated SO3-containing gases. In addition, the device and the process should be suitable for oxidizing hydrogen-sulphide-containing gases, such as occur, for example, in the refinery industry, in high concentrations to SO2.
