Abstract
The invention relates to a partial oxidation reactor (POX reactor) having a warm-up burner for producing synthesis gas by partial oxidation of fluid carbon-containing fuels in the presence of an oxygen-containing oxidant and to a process for startup of the partial oxidation reactor According to the invention the preheating of the partial oxidation reactor is carried out via a dedicated warm-up burner which is introduced via one of the media channels of the POX burner without any need to deinstall the entire POX burner.
Claims11
A partial oxidation reactor having a warm-up burner for producing synthesis gas by partial oxidation of fluid carbon-containing fuels in the presence of an oxygen-containing oxidant, comprising:
- (a) a partial oxidation burner,
- (b) a reactor vessel gastightly connectable to the partial oxidation burner,
- (c) a warm-up burner gastightly connectable to the partial oxidation burner,
- wherein the partial oxidation burner comprises:
- (a1) conduits for separately supplying a fluid carbon-containing fuel, the oxygen-containing oxidant and a moderator,
- (a2) a central first feed channel which has a circular cross section,
- (a3) a second feed channel coaxially and concentrically surrounding the first feed channel, wherein an annular gap is formed between the outer wall of the first feed channel and the inner wall of the second feed channel, and
- (a4) at least one further feed channel coaxially and concentrically surrounding the first feed channel, wherein an annular gap is formed between the outer wall of the second feed channel and the inner wall of the further feed channel,
- (a5) wherein the outer wall of the outermost feed channel forms the burner outer wall of the partial oxidation burner,
- (a6) a first detachable connecting device for gastightly connecting the partial oxidation burner to the reactor vessel,
- wherein the warm-up burner comprises:
- (c1) conduits for separately supplying the carbon-containing fuel or a further fuel gas and the oxygen-containing oxidant,
- (c2) a burner outer wall of the warm-up burner having a second detachable connecting device for gastightly connecting the warm-up burner to a feed channel of the partial oxidation burner, and
- (c3) an ignition apparatus,
- wherein the first detachable connecting device and the second detachable connecting device are configured as flanges which each comprise at least one sealing element and a multiplicity of detachable securing elements, wherein:
- the at least one sealing element of the second detachable connecting device is smaller than the at least one sealing element of the first detachable connecting device, and
- the multiplicity of detachable connecting elements for the second detachable connecting device is smaller than the multiplicity of connecting elements for the first detachable connecting device.
