）が供給されていることは３つまでもない。Next, the operation will be explained. When starting the fuel cell power generation device, first, preheating combustion is performed using a conventional fuel, such as city gas (13A). That is, combustion air (201) is introduced into the air chamber (B) from an air source, such as a blower, and then the pilot burner (4) is introduced by the discharge electrode (51).
1), city gas fuel (401) and combustion air (
By introducing the pilot burner (41)
) ignites. A pilot flame (403) is generated by ignition of the pilot burner (41), and by applying a voltage between the pilot burner (41) and the flame detection electrode (52) inserted into the pilot flame (403), the flame is generated. A current flows through it, and ignition is detected based on the current value, confirming ignition. When ignition is confirmed, the fuel chamber (A
) City gas (13A) for preheating is introduced into the fuel pipe (1
10), diffuses and mixes with the combustion air ejected from the air nozzle (210), and ignites when it comes into contact with the pilot flame (403), forming a combustion flame (102) on the main burner and reforming. Preheat the furnace (C). Thereafter, when the reformer (C) reaches a predetermined temperature, the introduction of city gas (13^) into the fuel chamber (A) is stopped. After the preheating is completed, the preheating combustion stops, and the raw material gas +11□0 is introduced into the reforming reaction tube (903) shown in Fig. 4, and the H2-enriched reformed gas is introduced into the power generation cell (902) to start power generation. do. Unconsumed after power generation 8. The cell off-gas (101) containing the fuel is again supplied to the reforming combustor (9O4), passes from the fuel chamber (^) through the fuel pipe (110), and burns the low-calorie off-gas in the main tank. At this time, combustion air (201
) are supplied in no more than three cases.

流値により着火検出を行っている。By the way, while the battery off-gas (ioi) is returning to the fuel chamber (A), if the main burner is not ignited or the load suddenly changes, the balance between the fuel gas flowing to the power generation cell (902) and the power generation load may change. - Sometimes extremely low-calorie battery off-gas (LOI) returns, causing the main burner to misfire. Therefore, it is necessary to keep the pilot burner (4I) in the ignited state at all times, and
There is a need for sufficiently high reliability of ignition confirmation. To confirm the ignition of the pilot burner (41), a flame detection electrode inserted into the pilot flame (403): (52
) and the pilot burner (41),
Detect the current flowing during that time 1. Ignition detection is performed based on the current value compared with a set value.
