Abstract

Disclosed herein is an apparatus for generating hydrogen by steam reforming. The apparatus comprises: a casing having provided in the central portion thereof a combustion section for producing high-temperature reaction heat; a flame guide provided such that it forms the outer wall of the combustion section while a space is provided outside thereof; a plurality of catalytic tubes arranged concentrically with respect to the combustion section in the space outside the flame guide; a feed supply manifold disposed at one side of the inside of the casing so as to distribute a feed supplied from the outside of the apparatus to each of the catalytic tubes; a reformate manifold connected with one end of each of the catalytic tubes so as to discharge a reformate obtained by the reforming reaction to the outside of the apparatus; and a support member which consists of an inner ring plate formed at one side of the inside of the casing and an outer ring plate disposed concentrically around the outer circumference of the inner ring plate and which has formed at the boundary between the inner and outer ring plates tube holes into which one end of each of the catalytic tubes is inserted. In the hydrogen generating apparatus, the structure of the support member supporting the plurality of catalytic tubes is simply divided into the inner ring plate and the outer ring plate, such that the expansion and shrinkage of the support member by thermal stress can be efficiently compensated for. As a result, deformation and breakdown of the support member caused by thermal stress can be prevented, thus improving the overall durability and stability of the hydrogen generating apparatus.

Description

technical field [0001] The present invention relates to a device for generating hydrogen by steam reforming, which continuously supplies hydrogen through a steam reforming reaction of natural gas or hydrocarbons. More particularly, the present invention relates to an apparatus for generating hydrogen using steam reforming, in which a support member for supporting a catalyst tube where a high-temperature reforming reaction occurs has an improved structure and increased durability, thereby ensuring stable performance and reliability. Background technique [0002] In recent years, due to the gradual increase in energy consumption with the development of technological innovation, the shortage of fossil fuel reserves and environmental pollution problems need to be solved urgently. At the same time, people's interest in hydrogen energy using clean hydrogen fuel as an energy carrier is also increasing. However, in the process of producing hydrogen from alternative energy sources (...
