COMBUSTION DEVICE, REFORMER, FUEL CELL POWER GENERATION SYSTEM, AND OPERATING METHOD OF REFORMER

摘要

PROBLEM TO BE SOLVED: To provide a combustion device carrying out safe combustion by detecting an ignition failure and a misfire even when burning fuel which hardly generates ions during combustion.

SOLUTION: The combustion device 10 comprises: a hydrogen-containing gas supply pipe 11 formed with a hydrogen-containing gas supply port 11h for leading out hydrogen-containing gas Gh; a fuel supply pipe 12 formed with a fuel supply port 12h for supplying hydrocarbon fuel Gc to the outer peripheral part of the hydrogen-containing gas supply pipe 11; and a temperature detecting means 18 detecting the temperature of flames formed when the hydrogen-containing gas Gh is burnt and when the hydrocarbon fuel Gc is burnt. The presence of flames formed in the combustion of the hydrogen-containing gas Gh hardly generating ions, is thereby detected by the temperature detecting means. A fuel cell power generation system comprising a reformer is constructed by installing this combustion device 10 at the reformer.
