Beschreibung
Zusammenfassung:	The invention discloses a method and a device for controlling MFT (Main Fuel Trip). The device comprises an OR gate, wherein a combustion flame loss signal and a power supply loss signal are used as input signals of the OR gate, and an output end of the OR gate is connected with all-flame loss MFT of a boiler. According to the method and the device, disclosed by the invention, main protection control logic of the all-flame loss MFT can be more reliable, a mis-operation action caused by an abnormal situation of a power supply can be avoided, and thus the normal production operation of a power station can be ensured.
