Abstract
Abstract Process and burner for the gasification of a finely divided solid fuel. An annulus of finely divided solid fuel is supplied to a reactor space via an annular outlet channel (12) of a burner. the burner being further provided with a plurality of outlet passages (10) for supplying a plurality of high velocity oxygen jets into the reactor space in such a manner as to intersect the annulus of finely divided solid fuel.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
89 words
Process for the gasification of a finely divided solid fuel, comprising supplying finely divided solid fuel as an annulus into a reactor space and introducing oxygen or an oxygen containing gas into said reactor space, allowing the oxygen or oxygen containing gas to react with the finely divided solid fuel for gasification of the latter, wherein at least part of the oxygen or oxygen containing gas is introduced into the reactor space as a plurality of high velocity jets arranged to intersect the annulus of finely divided solid fuel.
Claim 2
Dependent Claim
89 words
Process for the gasification of a finely divided solid fuel, comprising supplying finely divided solid fuel as an annulus into a reactor space and introducing oxygen or an oxygen containing gas into said reactor space, allowing the oxygen or oxygen containing gas to react with the finely divided solid fuel for gasification of the latter, wherein at least part of the oxygen or oxygen containing gas is introduced into the reactor space as a plurality of high velocity jets arranged to intersect the annulus of finely divided solid fuel.
Claim 3
Dependent Claim
24 words
Process as claimed in claim 1, in which the high velocity jets are uniformly distributed relative to the annulus of finely divided solid fuel.
Claim 4
Dependent Claim
28 words
Process as claimed in claim 1 or 2, in which the high velocity jets are arranged to intersect the annulus of finely divided solid fuel from the outside.
Claim 5
Dependent Claim
49 words
Process as claimed in claim 1 or 2, in which the high velocity jets are grouped in pairs, the jets of each pair being arranged at opposite sides inside and outside of the annulus of finely divided solid fuel and positioned as to intersect one another in said annulus.
Claim 6
Dependent Claim
39 words
Process as claimed in any one of the claims 1-4, in which part of the oxygen or oxygen containing gas is supplied to the reactor space as a core centrally arranged within the annulus of finely divided solid fuel.
Claim 7
Dependent Claim
46 words
Process as claimed in any one of the claims 1-5, in which part of the oxygen or oxygen containing gas is supplied to the reactor space as an annulus with low velocity surrounding the arrangement of finely divided solid fuel annulus and high velocity oxygen jets.
Claim 8
Dependent Claim
55 words
Burner for the gasification of a finely divided solid fuel, comprising an annular outlet channel (12) for finely divided solid fuel and a plurality of outlet passages (10) for oxygen or an oxygen containing gas, the axes of said outlet passages being arranged to intersect the extension of the annular outlet channel in downstream direction.
Claim 9
Dependent Claim
55 words
Burner for the gasification of a finely divided solid fuel, comprising an annular outlet channel (12) for finely divided solid fuel and a plurality of outlet passages (10) for oxygen or an oxygen containing gas, the axes of said outlet passages being arranged to intersect the extension of the annular outlet channel in downstream direction.
Claim 10
Dependent Claim
27 words
Burner as claimed in claim 7, in which the outlet passages for oxygen or oxygen containing gas are uniformly distributed with respect to the annular outlet channel.
Claim 11
Dependent Claim
20 words
Burner as claimed in claim 7 or 8, in which the outlet passages are arranged around the annular outlet channel.
Claim 12
Dependent Claim
54 words
Burner as claimed in claim 7 or 8, in which the outlet passages are grouped in pairs, the outlet passages of each group being arranged at opposite sides inside and outside of the annular outlet channel and having their axes arranged to intersect one another substantially in the extension of the annular outlet channel.
