FIELD: burner control systems. SUBSTANCE: device has load condition setting unit 1, load speed control unit 2, excitation signal shaping unit 3, and load control unit 4. Load condition setting unit 1 is built up of three variable resistors 5-7, six fixed resistors 8-13. Unit 3 has buffer device 14, four resistors 15,16,20,21, power supply 17, light- emitting element 18, and optocouple light-emitting element 19. Unit 4 has a.c. voltage source 22, electron pump 23, two diodes 24,25, blower motor 26, light detector 27, optocouple light-detecting element 28, and capacitor 29. EFFECT: improved efficiency of device and method for burner control due to production of optimal quantity of heat. 5 cl, 5 dwg
