Patent ID: 8017088

Claim:
A fuel reformer comprising: a reactor body including a plurality of reaction substrates configured to generate thermal energy through an oxidation reaction of a first reactant including a fuel, the reactor body further being configured to generate a reforming gas through a reforming reaction of a second reactant including the fuel; and a preheating unit configured to ignite and burn the first reactant in order to preheat the reactor body, the preheating unit comprising: a housing enclosing the reactor body; and a burner disposed in the housing to ignite and burn the first reactant external to the reactor body, wherein the housing has: a first injection hole located adjacent to the burner and configured to supply the second reactant to the plurality of reaction substrates; and a second injection hole located adjacent to the burner and configured to supply the first reactant through the burner, and wherein the reactor body has: a third injection hole at a first side of the reactor body for injecting the burnt first reactant into the reactor body; and a discharge hole at a second side of the reactor body for discharging the oxidized first reactant, the second side facing oppositely away from the first side.
