Gas Reformer Furnace
Abstract: In this gas reformer furnace (1) a furnace main body (11) forms a flow path (100) wherethrough a pyrolysis gas supplied from a gasification furnace (81) flows. A fill layer holding section (2) is provided in the flow path (100) and holds a char fill layer (22) filled with char. In a space more to the upstream side than the char fill layer (22) in the flow path (100) a tar combusting unit (3) supplies an oxygen-containing gas to the pyrolysis gas thereby causing the tar contained in the pyrolysis gas to combust before the pyrolysis gas passes through the char fill layer (22). A steam ejection unit (4) ejects steam from an ejection port provided within the char fill layer (22). In this manner the concentration of tar contained in the pyrolysis gas can be reduced drastically. Fig 1.

Claims
1. A gas reforming furnace for reforming a pyrolysis gas supplied from a gasification furnace, comprising: a furnace body forming a flow path for the pyrolysis gas; a filled layer retainer provided in said flow path and retaining a char filled layer filled with char; a tar combustor that supplies an oxygen-containing gas to said pyrolysis gas in a space upstream of said char filled layer in said flow path to burn tar contained in said pyrolysis gas before said pyrolysis gas passes through said char filled layer; and a steam ejector that ejects steam from an ejection port provided inside said char filled layer or in proximity to said char filled layer.
2. The gas reforming furnace as claimed in claim 1, wherein said filled layer retainer includes a retaining member that has a plurality of holes and retains said char filled layer from underside.
3. The gas reforming furnace as claimed in claim 1 or 2, further comprising: a char supply part that supplies char to said filled layer retainer; a layer-thickness acquisition part that acquires a thickness of said char filled layer; and a controller that controls an amount of char supplied by said char supply part, on the basis of said thickness.
4. The gas reforming furnace as claimed in any one of claims 1 to 3, wherein a length of said tar combustor from a supply position of said oxygen-containing gas to a surface of said char filled layer in a direction of flow of said pyrolysis gas is greater than the thickness of said char filled layer.
5. The gas reforming furnace as claimed in any one of claims 1 to 4, wherein a temperature in a space downstream of said char filled layer in said flow path is lower than a temperature in said char filled layer.
Specification
I/We Claim:
1. A gas reforming furnace for reforming a pyrolysis gas supplied from a
gasification furnace, comprising:
a furnace body forming a flow path for the pyrolysis gas;
a filled layer retainer provided in said flow path and retaining a char filled layer filled with char;
a tar combustor that supplies an oxygen-containing gas to said pyrolysis gas in a space upstream of said char filled layer in said flow path to burn tar contained in said pyrolysis gas before said pyrolysis gas passes through said char filled layer; and
a steam ejector that ejects steam from an ejection port provided inside said char filled layer or in proximity to said char filled layer.
2. The gas reforming furnace as claimed in claim 1, wherein
said filled layer retainer includes a retaining member that has a plurality of holes and retains said char filled layer from underside.
3. The gas reforming furnace as claimed in claim 1 or 2, further
comprising:
a char supply part that supplies char to said filled layer retainer;
a layer-thickness acquisition part that acquires a thickness of said char filled layer; and
a controller that controls an amount of char supplied by said char supply part, on the basis of said thickness.
4. The gas reforming furnace as claimed in any one of claims 1 to 3,
wherein
a length of said tar combustor from a supply position of said oxygen-containing gas to a surface of said char filled layer in a direction of flow of said pyrolysis gas is greater than the thickness of said char filled layer.
5. The gas reforming furnace as claimed in any one of claims 1 to 4,
wherein
a temperature in a space downstream of said char filled layer in said flow path is lower than a temperature in said char filled layer.
