CONTROL SYSTEM FOR ADJUSTMENT OF IGNITION FLAME OF DEVICE POWERED BY COMBUSTIBLE GAS Russian patent published in 2022 - IPC F23N1/00 F23N5/02 

FIELD: engine building.

SUBSTANCE: control system for adjustment of ignition flame of a device powered by combustible gas is proposed. Gas-powered device (200) contains ignition burner (1) for generation of ignition flame, main burner (2) for generation of main flame, and valve node (300), which contains auxiliary valve (3), which is placed upstream from ignition burner (1) to provide a possibility of/to interrupt gas flowing towards ignition burner (1), and main valve (4), which is placed upstream from main burner (2) to provide a possibility of/to interrupt gas flowing towards main burner (2). A state of valve node (300) is transferring between an off state, in which auxiliary valve (3) is closed, an ignition state, in which auxiliary valve (3) is open, and main valve (4) is non-working to provide a possibility of gas flowing towards main burner (2), and an on state, in which auxiliary valve (3) is open, and main valve (4) is working to provide a possibility of gas flowing towards mentioned main burner (2). Control system (100) contains detection device (19) adapted for detection of at least the ignition state of valve node (300) and formation of a state signal, which is the detected state of valve node (300), and control unit (20) containing timer (24). Control unit (20) is functionally connected to detection device (19) to receive the state signal and to actuator (10) for auxiliary valve (3) to close the mentioned valve. Control unit (20) is configured to start mentioned timer (24), when the state signal received by detection device (19) is the ignition state, and to actuate actuator (10) for auxiliary valve (3) to close the mentioned valve, when time measured by timer (24) reaches a preset limit, thereby extinguishing ignition flame.

EFFECT: obtainment of a control system for adjustment of ignition flame of a device powered by combustible gas.
