Abstract
A system of product gas collecting conduits for a steam reformer, containing a plurality of reaction tubes within a reformer housing, for the production of synthesis gas, comprising: a) a product gas collecting conduit arranged outside the reformer housing of the steam reformer, b) several port tubes arranged along the length of the conduit for connecting one reaction tube each to the product gas collecting conduit, c) at least one windshield for the protection of the product gas collecting conduit against wind and draft.
Claims18
A system of product gas collecting conduits for a steam reformer, containing a plurality of reaction tubes within a reformer housing, for the production of synthesis gas, the system comprising:
- a) a product gas collecting conduit arranged outside the reformer housing of the steam reformer and exposed to the ambient air, containing a jacket tube and an inner tube extending concentrically along an entire length of the product gas collecting conduit, wherein the space between inner tube and jacket tube is filled with insulating material;
- b) several, at least one first and one last, port tubes arranged along the length of the product gas collecting conduit for connecting one reaction tube each to the product gas collecting conduit;
- and
- c) a windshield, wherein the windshield is designed and arranged such that the windshield protects the product gas collecting conduit against wind and draft at least on a part of the length and the circumference of the product gas collecting conduit.

- a) a product gas collecting conduit arranged outside the reformer housing of the steam reformer and exposed to the ambient air, the product gas collecting conduit containing a jacket tube and an inner tube extending concentrically along an entire length of the product gas collecting conduit, wherein the space between inner tube and jacket tube is filled with insulating material;
- b) several, at least one first and one last, port tubes arranged along the length of the product gas collecting conduit for connecting one reaction tube each to the product gas collecting conduit;
- and
- c) a windshield that is configured to reduce convection heat transfer from the product gas collecting conduit that is attributable to wind and draft at least on a part of the length and the circumference of the product gas collecting conduit.
