FUEL REFORMING REACTOR AND METHOD FOR MANUFACTURE THEREOF

摘要

A fuel reforming reactor for reforming a hydrocarbon fuel into a gas rich in hydrogen, characterized in that a chromium oxide layer is formed on at least a part of the surface of an steel material constituting the reforming reactor; and a method for manufacturing the fuel reforming reactor. The reforming reactor is free from the generation of red scales through the steam oxidation of the surface of the steel material constituting the reforming reactor, even when it is exposed to a low oxygen concentration and/or high steam concentration atmosphere at a high temperature, has high heat resistance, is light in weight, exhibits high reliability and a long useful life, and can be manufactured at a low cost with ease by using the method according to the invention, and thus is of great utility value in industry.
