CONTROL FOR CATALYTIC COMBUSTOR

摘要

A fuel injector ( 11 ) supplies liquid fuel to a catalytic combustor ( 9 ) of a fuel reforming device during startup of a fuel reforming device. A controller sets the injection amount (Qf) for liquid fuel to a first injection amount (Qf 1 ) during a predetermined time (t 1 ) after starting fuel injection. After the predetermined time, the injection amount (Qf) is set to a second injection amount (Qf 2 ) which is larger than the first injection amount (Qf 1 ). When the elapsed time after starting fuel injection is smaller than a value (t 1 ), the discharged amount of uncombusted fuel is reduced by setting the injection amount (Qf) to a minimum injection amount (Qf 1 ) which allows ignition and combustion in the catalyst.
