THERMAL EFFICIENCY IMPROVED FUEL REFORMER USING INTERNAL HEAT EXCHANGING STRUCTURE

摘要

The present invention relates to a concentric tube fuel reformer for producing hydrogen-rich reformed gas by inducing a reaction on a reforming catalyst by mixing hydrocarbons such as natural gas, city gas, LPG and naphtha and steam, and more particularly, The present invention relates to a fuel reformer that improves thermal efficiency by installing a structure for improving heat exchange between a reforming reaction raw material and a generated reformed gas discharged after the reaction so that the reaction raw material preheats and cools the generated reformed gas effectively.;In the present invention, the reforming catalyst layer is formed by an internal structure which effectively recovers heat from the generated reformed gas to the reaction raw material with the effect of reducing heat loss due to the reduction of the surface temperature of the upper part of the fuel reformer by improving the internal heat exchange between the supplied reactant and the generated reformed gas. By effectively preheating the reaction raw material until the introduction, it is possible to reduce the amount of fuel to be supplied from the burner, thereby improving the thermal efficiency of the fuel reformer.;Hydrogen Production, Hydrocarbons, Steam Reforming, Fuel Reformers
