摘要：
A foraminous burner liner for a gas abatement system has a hollow body defined by a wall that has a plurality of interconnected concentric layers. Each layer of the wall has a regular openwork mesh, and the regular openwork mesh of each layer is out of phase with one or more adjacent layers. The wall has sufficient layers so that the wall is optically opaque when viewed externally in any radially inward direction normal to the wall. A single layer of the foraminous burner liner is shown in Figure 5 and a ten-layer foraminous burner liner is shown in Figure 7. The invention creates a foraminous burner liner without a join-line and thus creates a burner liner with predictable burner properties. The liner may be made by additive manufacturing and may be made from a high temperature oxidation resistant alloy.

wherein each layer of the wall comprises a substantially regular openwork mesh; wherein the substantially regular openwork mesh of each layer is configured such that it isout of phasewith one or more adjacent layers, and whereinthe wall comprises sufficient layers arranged such that the wall is optically opaque when viewed externally in any radially inward direction normal to the wall.
2. A foraminous burner linerfor a gas abatement system, said bumer liner comprising a hollow body defined by a wall, said wall comprising a plurality of interconnected layers, wherein a layer comprises at least one right-handed substantially helical strut coupled to at least one left-handed substantially helical strut.
3. The foraminous burner liner according to claim 2 wherein a layer is configured such that itis out of phase with one or more adjacent layers, and preferably wherein the wall comprises sufficient layers arranged such that the wall is optically opaque when viewed externally in any radially inward direction normal to the wall.
4. The foraminous burner liner according to either of claims 1 or 3, wherein the wall comprises a greater number of layers than required to achieve optical opacity, preferably at least twice the number of layers required to achieve optical opacity, more preferably at least three times the number of layers required to achieve optical opacity.
5. The foraminous burner liner according to any preceding claim, wherein the wall comprises from about 3 to about 20 layers, preferably from about 4 to about 9 layers.
6. The foraminous burner liner according to any preceding claim, wherein a right- handed substantially helical strut and a left-handed substantially helical strut of each layer each complete more than one complete helix turns.
/; The foraminous burner liner according to claim 6, wherein a substantially helical strut of each layer intersects with and is integrally formed with a substantially helical strut of an adjacent layer.
8. The foraminous burner liner according to any of claims 1 to 6, wherein each layer comprises a plurality of circumferentially spaced right-handed substantially helical struts coupled to a plurality of circumferentially spaced left-handed substantially helical struts.
9. The foraminous burner liner according to claim 8 when dependent on claims 1 to 5 wherein each substantially helical strut completes a part of a helix turn, preferably less than one helix turn.
10. The foraminous burner liner according to claim 8 when dependent on claims 1 to 5, or claim 9, wherein one or more radially extending spacers couple a first layer to an adjacent layer.
11. The foraminous burner liner according to claim 10, wherein a radially extending spacer is in the form a longitudinally extending stave.
12. The foraminous burner liner according to any preceding claim, wherein the plurality of interconnected layers are concentrically arranged.
13. The foraminous burner liner according to any preceding claim, wherein the hollow body is substantially tubular or frustoconical.
14. The foraminous burner liner according to any preceding claim, wherein an outermost layer of the wall is coupled to a perforated sheet defining an outer surface of the foraminous burner liner, preferably wherein perforations of the sheet are substantially aligned with openings in the outermost layer of the wall.
15. An additive manufactured foraminous burner liner according to any preceding claim, preferably wherein the burner liner is manufactured using powder bed fusion.
