PURPOSE:To quicken countermeasure to an abnormality and restoration from a trouble by a method wherein a variable resistor unit is connected to a combustion condition sensor and first decision, whether the combustion condition is discontinuous or normal, as well as the second decision, whether the combustion is lacking oxygen or normal, are decided by changing the value of resistance of the variable resistor unit. CONSTITUTION:A resistor control means 22C opens the point (a) thereof and first deciding means 22A compares the differential pressure of the combustion condition sensor 10 and the resistor 9 of the variable resistor unit 89 with a preset a voltage by inputting the differential pressure from a point (b). When it is lower than the set voltage, the combustion condition is decided that it is discontinuous and when it is higher, the combustion condition is decided that it is normal. Next, the resistor control means 22C grounds the point (a) thereof and the second deciding means 22B compares the differential pressure of the combustion condition sensor 10 and the parallel resultant resistance of the resistors 9, 8 with a preset voltage by inputting the differential pressure from the point (b). When it is lower than the set voltage, the combustion condition is decided that it is normal but when it is higher than the set voltage, it is decided that oxygen is lacked. These two kinds of input conditions are made alternately and the dicisions are effected alternately. |

PURPOSE:To prevent a secondary disaster, by detecting automatically a state of repair work while an independent stopcock is being kept forgotton to tighten up. CONSTITUTION:At the time when an independent stopcock 73a is forgotten to tighten up, a signal treatment circuit 74 works by detecting that a pipeline 19 has become lower than predetermined pressure by a pressure detector 71 when a main stopcock 20 is opened and a solenoid valve 72 is interrupted. As the pressure in the pipeline 19 becomes a predetermined level due to a matter that the solenoid valve 72 and the main stopcock 21 are made open by applying separately a pulse signal to the signal treatment circuit 74 after elimination of a cause of disorder such as discovery of a matter that the individual stopcock 73a has been forgotten to tighten up after interruption of the main stopcock 21, it is eliminated that the solenoid valve 72 becomes workable. With this construction, secondary disaster due to a leak from the individual stopcock 73 after repair work of the main stopcock 21 can be prevented. |

PURPOSE:To enable a proper control over combustion and improve safety and reliability without being influenced by a turned-ON or a turned-OFF condition of suction by a method wherein a holding circuit for holding a detected condition when the sensor detects an operation of an energization fan at once is provided. CONSTITUTION:An air pressure switch 9 is turned on by a pneumatic pressure suctioned when a purging is performed in advance by a fan 2, a relay 23 is operated to close a contact point 23a and to form a self-holding circuit. Further, by closing of contact point 23b, a solenoid valve 5 is released by a driving circuit 24, fuel is supplied to a combustion part 4 and a pulse operated combustion is started by an ignition electrode 6a. Then, the operation of the fan 2 is stopped, the air pressure switch 9 repeats its turned-on or turned-off condition as the flap valve 3 is opened or closed, and a supplying of fuel under an operation of the solenoid valve 5 can be continued with a self-holding of the relay 23. When a fire sensor 10 detects a stopped operation or a misfire at the combustion part 4, a clear contact point 22 is released and then the self-holding circuit for the relay 23 is reset. |

PURPOSE:To prevent production of self-oscillation even during operation at a low flow rate, by a method wherein a volume resonant frequency, determined by the volume of a pipeline on the outlet side running from the outlet of a pressure regulating device such as proportional control valves to resistor having pores, coincides with the self- oscillating frequency of the pressure regulating device. CONSTITUTION:With relation to burner nozzle 7, a resistor 12 having pores is located in a pipeline 11 on the outlet on the output side. A relation between the pores and the volume of a pipeline running from the outlet of a pressure regulating device 1 to a resistor 12 forms a volume resonant frequency which coincides with the self-oscillating frequency of the pressure regulating device 1. When primary vibration such as disturbance occurs to the valve part of the pressure regulating device 1, the influence produces a pressure wave, which is propagated within the line 11 on the outlet side and produces a reflecting wave at the resistor 12 due to a change in a sectional area and returns to the upper stream side. In which case, a frequency component, centering around the volume resonant frequency determined by the pores in the resistor 12 and the volume of the line on the outlet side, conducts reciprocating movement at the pore part and produces heat energy to be dissipated, and is almost kept from being contained in a reflecting component. This enables prevention of oscillation of the pressure regulating device 1. |

PURPOSE:To normally provide a highly precise air-fuel ratio irrespective of a change in an atmosphere temperature, by a method wherein the pressure receiving part of a differential pressure detector is structure such that two elastic diaphragms in an approximately identical shape are located coaxially and axially reversely to each other. CONSTITUTION:When the 0 point of a differential pressure detector 10 is adjusted at a temperatur t0 deg.C, if a temperature rise DELTAt occurs, a rubber diaphragm 20 and a rubber diaphragm 21 are thermally expanded, beads 20B and 21B are decreased in radius of curvature and increased in an internal stress, and the central parts are going to be moved respectively downward and upward. The diaphragms are axially equal in the size and reverse in a direction, whereby they are mutually offset and do not come out, a core 26 is prevented from displacement, and the middle point is also prevented from deivation. This permits provision of a normally high-precise air-fuel ratio irrespective of a charge in an atmospheric temperature. |
