FUEL CELL POWER GENERATING EQUIPMENT AND PURGING METHOD OF INFLAMMABLE GAS IN FUEL CELL POWER GENERATING EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To surely supply air to a combustor even in such a case that a gas turbine has stopped at the time of purging of inflammable gas during the stoppage of a fuel cell power generating equipment.;SOLUTION: In the fuel cell power generating equipment, in which anode exhaust gas Gea of a fuel cell 3 housed in a pressure vessel 4 capable of introducing air Ac from a compressor 24 is supplied to a combustion chamber 1b of a reformer 1 and reforming of fuel gas Gf is made by heat of the anode exhaust gas Gea, a conduit 27 feeding the air Ac from the pressure vessel 4 to a gas turbine 21 side and an upstream side of an air preheater 23 of an air supply pipe 11 for feeding the air Ac preheated by the air preheater 23 to the combustor 12 are connected by a conduit 32 equipped with a shut-off valve 31.;COPYRIGHT: (C)2005,JPO&NCIPI
