Fuel reforming apparatus and electric power generating system having the same

摘要

A cylindrical fuel reforming apparatus covered with an insulating layer 16 comprises a fuel flow passage 1 and a catalyst bed 3. A cooling jacket 10 is supplied with air. Gas, preferably methane, from inlet pipe 6 and air 7 are partially combusted and steam from pipe 11 is swirled by a swirling device 22 upstream of the catalyst. The resulting hydrogen enriched unburned gas 13 is burned in a gas turbine which drives a electric power generator. Exhaust gas from burner is delivered to an exhaust heat recovery boiler containing water. Steam is thus generated and fed back to the reformer, thereby enabling heat to be recovered.
