Abstract
In a process for producing elemental sulfur by combustion of hydrogen sulfide or a hydrogen-sulfide-containing gas, in particular a Claus process, the hydrogen sulfide or the hydrogen-sulfide-containing gas undergoes partial combustion by using a first device in the form of a burner to which usually air is added as an oxidizing agent and which is connected to the combustion chamber. The hydrogen sulfide or the hydrogen-sulfide-containing gas undergoes further combustion by means of a second device in form of at least one nozzle which is also connected to the combustion chamber and through which oxygen or an oxygen containing gas is fed into the combustion chamber, as a result of which the hydrogen sulfide or the hydrogen-sulfide-containing gas is subjected to afterburning and is then fed to a waste-heat boiler and thereafter to one or more reactors.
