PURPOSE:To provide the combustion control system, capable of combusting fuel without producing a black smoke, by controlling combustion-air flow and fuel flow appropriately through provision of various control means constituted by an oxygen- density detector, means for detecting the density of carbon monoxide, regulator, signal selecting means, regulating and controlling unit, etc. CONSTITUTION:The first control means is constituted by the oxygen-density detector 2 and the first regulator 3 and the second control means is constituted by the second regulator 5 and means 4 for detecting the density of carbon monoxide. Further, regulating and controlling unit 7 is used as the third control means. Signal selector 6 is used as signal selecting means which selects either one of the first control signal S2 and the second control signal S4 and gives it to the unit 7 as set signal S5. This signal selector 6 is designed to select either one of the two control signals S2, S4 having a higher signal level. |
