专利汇可以提供Shield tube supports专利检索，专利查询，专利分析的服务。并且An improved support is disclosed for furnace shield tubes, which are located between the radiant and convection sections of industrial furnaces, and which, since they are exposed to radiant heat, are subject to significant weakening. In the preferred embodiment, a hollow pipe serves as a beam support for the shield tubes, the support being extensively insulated to minimize radiant heat input and being cooled by air passing inside it as induced by natural draft available from the furnace. Air from outside the furnace is drawn into the hollow support, cools it and passes out into the furnace stack above the convection section. The support beam is cooled by air while the supports on which the shield tubes rest are cooled by conduction, either into the air cooled support or into the shield tubes. Contact of the supports with radiant energy is avoided.，下面是Shield tube supports专利的具体信息内容。

权利要求

1. A method of supporting furnace tubes exposed to high temperatures at which metal support beams for said tubes are subject to creep failure comprising: a. providing an air passageway through each of said support beams; b. admitting cool ambient air to one end of said passageways of (a) and flowing said air therethrough thereby increasing its temperature; c. removing said heated air of (b) from the passageway of (a) and discharging it into the furnace at a location having negative pressure relative to the pressure of said ambient air; d. insulating each of said tube support beams to limit heat input to said supports sufficient to allow the operating temperature of said support beams to be reduced by air passing through said passageways of (a) to below the temperature at which creep failure occurs, e. supporting said furnace tubes on pairs of metal supports welded to said beams, one of said supports being within said insulation of (d) and supporting a tube immediately adjacent said insulation and the second of said supports supporting a second tube disposed further away from said passageway and being welded to said first support and outside said insulation of (d).

2. A support structure for furnace tubes exposed to high temperatures in a furnace having radiant and convection sections and where metal support beams for said tubes are subject to creep failure comprising: a. an elongated air-cooled support beam having a passageway therethrough with one end of said passageway open to cool ambient air outside the furnace and the other end communicating with a location within the furnace having a negative pressure relative to the pressure of said ambient air; b. insulation completely surrounding said support beam of (a) where said beam is exposed to high temperatures within the furnace, said insulation having sufficient resistance to heat transfer to permit the support beam to operate below the temperature at which creep failure occurs; c. at least one pair of metal supports attached to said support beam of (a) for holding an associated pair of furnaCe tubes, the first of said supports being welded to said beam and completely covered by said insulation of (b) for supporting the first of said furnace tubes, the second of said supports being welded to said first support for supporting said second furnace tube further away from said support beam of (a).

3. The support structure of claim 2 wherein said second support of (c) is insulated against heat input from the furnace.

4. The support structure of claim 2 wherein said first support of (c) is T-shaped and attached at the base of the T to said support beam.

5. The support structure of claim 2 wherein said second support of (c) is Y-shaped and attached at the base of the Y to the crossbar of said T-shaped support.

6. The support structure of claim 2 wherein said support beam of (a) comprises a hollow cylindrical tube fabricated of a metal having high temperature creep resistance.

7. The support structure of claim 2 wherein said furnace tubes are horizontal shield tubes disposed between said radiant and convection sections.

8. The support structure of claim 7 wherein said shield tubes are supported by a plurality of said support beams extending normal to the axes of said furnace tubes and supported near the ends of said beams by the furnace structure, whereby the support beams are subject to bending load by said shield tubes.

9. The support structure of claim 2 wherein said furnace location of negative pressure is subsequent to the convection section.

10. The method of claim 1 further comprising sensing the temperature of the air exiting said passageway of (a) as indicative of the heat limiting ability of said insulation.
