GAS BURNER MICROCONTROLLER AUTOMATIC DEVICE Russian patent published in 2024 - IPC F23N5/20 

FIELD: power engineering.

SUBSTANCE: invention relates to control of burners. Gas burner microcontroller automatic device contains a flame sensor, the output of which is connected through a signal amplifier to the microcontroller input, to outputs of which a unit of transistor keys is connected, containing at least two transistor amplification cascades, operating in key mode, and with possibility to control signal lamp and ignition transformer, LED indicators. Coils of two electromagnetic relays of relay unit are connected to output circuits of transistor amplifying cascades, which by their contacts switch circuits of electromagnetic gas valve, signal lamp and ignition transformer. Transistor switch unit additionally controls signal lamp and ignition transformer. Microcontroller machine contains five LED indicators reflecting the state of the device. Power consuming elements of the device are supplied from a stabilized power supply unit, microprocessor program is executed with possibility to control operating parameters of combustion process with indication of device operation, signal amplifier from the flame sensor is configured with the possibility of rebuilding using the operating mode microcontroller software.

EFFECT: increased reliability of the device and improvement of its operational characteristics.
