FIELD: turbines or turbomachines.
SUBSTANCE: invention relates to fuel feed system (20) for turbomachine. Supply system (20) comprises starter circuit (120), at least one first hydraulic resistance (124, 136) and blowdown circuit (130). Purging circuit (130) comprises pipeline (131), having opening (133) outside supply system (20). Purging circuit (130) is configured to create a blowdown air flow between nozzle (126) of starter and opening (133) through first hydraulic resistance (124, 136). Supply system (20) comprises means (141) for measuring pressure characteristic value, which is configured to measure characteristic pressure value (Pm) between nozzle (126) of starter and first hydraulic resistance (124, 136), when purging air flows between nozzle (126) of starter and first hydraulic resistance (124, 136).
EFFECT: disclosed is clogging control in blowdown circuit of starter nozzle for turbomachine.
