FIELD: industrial furnaces of power stations. SUBSTANCE: method of automatic combustion control consists in reduction of definite concentration of free oxygen till preset concentration of carbon monoxide in waste gases is exceeded. Then definite concentration of free oxygen rises and after reduction of concentration of carbon monoxide, concentration of free oxygen reduces again. System includes programmer with definite program for changing definite concentration of free oxygen in waste gases depending on ratio of present concentration of carbon monoxide and preset concentration of carbon monoxide. EFFECT: optimization of combustion process. 5 cl, 2 dwg
