Abstract
Abstract Disclosed is a reactor for gasifying coal including a vortex burner. Helical ribs are arranged in the inner combustion gas supplying conduit of the burner to impart a spiral trajectory to the gas and also the coal-water suspension which suspension is supplied in the annular space between the inner conduit and an outer concentric conduit. Means are provided for adjustably supporting the ribs inside the inner conduit. In addition, other rib supporting arrangements and also burner structure for supplying the coal-water slurry centrally are disclosed.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
156 words
A reactor for coal gasification wherein partial oxidation of a solid material containing carbon in the presence of water produces a carbon monoxide and hydrogen containing gas, comprising a vortex burner connected to said reactor having an inner cylindrical conduit for admission of oxygen or combustive air and an outer concentric cylindrical conduit cooperating with said inner conduit to define an annulus for receipt of said solid material and water, and generally inwardly projecting guide means comprising helical ribs inclined relative to the longitudinal axis of the inner conduit and disposed within said inner conduit for establishing generally spiral motion to said oxygen or combustive air as it moves through said inner conduit wherein said ribs are at one end connected by articulation with said inner conduit and are glidingly supported at the other end in a recess of an annular nut which nut is adjustably connected to said inner conduit at the inner periphery thereof.
Claim 2
Dependent Claim
156 words
A reactor for coal gasification wherein partial oxidation of a solid material containing carbon in the presence of water produces a carbon monoxide and hydrogen containing gas, comprising a vortex burner connected to said reactor having an inner cylindrical conduit for admission of oxygen or combustive air and an outer concentric cylindrical conduit cooperating with said inner conduit to define an annulus for receipt of said solid material and water, and generally inwardly projecting guide means comprising helical ribs inclined relative to the longitudinal axis of the inner conduit and disposed within said inner conduit for establishing generally spiral motion to said oxygen or combustive air as it moves through said inner conduit wherein said ribs are at one end connected by articulation with said inner conduit and are glidingly supported at the other end in a recess of an annular nut which nut is adjustably connected to said inner conduit at the inner periphery thereof.

Claim 12
Dependent Claim
44 words
The reactor of claim 10 characterized by a cylindrical orifice in the conical tip of the conduit for oxygen or the conduit for combustive air, the length of which is equal to one-third to two-thirds of the orifice diameter of the outer conduit tip.
Claim 13
Dependent Claim
34 words
