摘要： The present invention relates to a process for providing elemental sulphur from a sour gas comprising hydrogen sulphide and at least one oxidizable carbon compound, wherein the process comprises the steps of: a Claus process step, wherein the sour gas is oxidized in presence of a first oxidant stream with a oxygen content of at least 21 % (v/v), wherein a part of the hydrogen sulphide is converted to sulphur dioxide, the at least one carbon compound is at least partly converted to carbon monoxide, and the sulphur dioxide is reacted with the remaining hydrogen sulphide yielding elemental sulphur and a tail gas comprising carbon monoxide, and an incineration step, wherein the tail gas is oxidized in presence of a second oxidant stream, wherein the carbon monoxide is converted to carbon dioxide, and wherein the second oxidant stream is characterized by an oxygen content of at least 21 % (v/v).

摘要： The invention relates to a method for operating a burner used in the thermal step of a Claus process. The burner comprises at least one combustion air port, at least one oxygen port, and at least one fuel port. The oxidant flow is made up of an oxygen flow of technical pure oxygen with an oxygen concentration of at least 90 vol-%, preferably at least 99 vol-%, and if necessary of a second gas flow, and it is determined whether the oxygen flow is below a pre-set minimum flow and if the oxygen flow is below a pre-set minimum flow the air flow is split into a main air flow and a side air flow and the oxygen flow is combined with the side air flow creating an oxygen-enriched side air flow which is fed to the oxygen port.

摘要： The invention relates to a method for partial reduction of SO2, wherein a SO2 stream, an oxidant and a gaseous fuel are fed to a burner and reacted in a flame reaction. The burner comprises at least one supply opening for the SO2 stream, at least one supply opening for the oxidant and at least one supply opening for the gaseous fuel, and a burner head (1) with first injection sets (7, 8) and second injection sets (9). First injection sets (7, 8) are arranged in a first section (4) of the burner head (1) and second injection sets (9) are arranged in a second section (5) of the burner head (1). The stoichiometric ratio of SO2, fuel and oxidant supplied through the first injection sets (7, 8) is different from the stoichiometric ratio of SO2, fuel and oxidant supplied through the second injection sets (9).

摘要： The invention relates to a burner, particularly Low-NOx-burner, for generating a flame by combustion of a fuel, comprising: a tile (15, 15a, 15b) surrounding an opening (2, 2a, 2b) of the tile (15, 15a, 15b) extending along a burner axis (12), the tile (15, 15a, 15b) further comprising a front side (20) and a rear side (21) facing away from the front side (20), wherein the rear side (21) comprises an air inlet (10, 10a, 10b) connected to said opening for feeding air (A, A', A") into said opening (2, 2a, 2b), and wherein said front side (20) comprises a discharge outlet (9, 9a, 9b) connected to said opening (2, 2a, 2b) for discharging a flame (30) generated by the burner (1) into a surrounding area (S), and wherein the tile (15, 15a, 15b) further comprises an inside (22) facing said opening (2, 2a, 2b) as well as an outside (23) facing away from said opening (2, 2a, 2b). According to the invention the burner (1) further comprises at least one oxygen lance (5) extending along the burner axis (12) in a first recess (17) of said tile (15, 15a, 15b), the at least one oxygen lance (5) having an ejection nozzle (6) at an end region of the at least one oxygen lance (5) for ejecting oxygen (O), particularly such that the oxygen (O) is at first ejected into a colder flue gas region (31) surrounding the relatively hotter flame (30) generated by the burner (1). Further, the invention relates to a method for generating a flame (30).
