摘要： PURPOSE: To prevent fuel supply from uselessly stopping each gusty wind to improve convenience by momentarily inhibiting stoppage of fuel supply to continue combustion even if a fan is controlled in an up-mode and CO concentration exceeds an allowable value when gas quantity detected is smaller than a threshold. CONSTITUTION: When gusty wind blows in, wind velocity detected by a wind velocity sensor 6 rapidly decreases. Also, when gusty wind blows in, combustion air is not adequately fed by a fan 2 to make a combustion condition at a burner 1 worse, so that CO concentration in exhaust gas momentarily increases with a little time lag. Since an increase in CO concentration at this time is momentary, human organism is not affected thereby. A momentary retention means 7 judges blowing-in of gusty wind when wind velocity sensed by the wind velocity sensor 6 lowers below a threshold, and cancels information of CO concentration to temporarily retain stoppage of gas supply even when the fan 2 is controlled in an up-mode and the CO concentration exceeds an allowable value.

摘要： PURPOSE: To provide a combustor capable of safely dealing with live gas leakage of fuel gas. CONSTITUTION: There is provided a contact combustion type CO sensor 20 having a CO detection device. The CO sensor 20 is constructed as one capable of detection of hydrocarbon(CmHn) by raising the temperature of the CO detection device. After combustion interruption decision means 24 decides a combustor to interrupt a combustion operation, sensor temperature adjustment means 25 raises the temperature of the CO detection device of the CO sensor 20 to enable the detection of CmHn concentration. When the CmHn detected concentration in an apparatus detected by the CO sensor 20 reaches a combustion obstruction reference concentration, a dangerous combustion obstruction unit 44 obstructs starting of the next combustion operation, while when the CmHn detected concentration is less than the combustion obstruction reference concentration but exceeds safe concentration, a CmHn exhaust operation control unit 45 rotates a combustion fan 5 for exhaustion of CmHn. There is further provided a CmHn safety device 38 for preparing the next combustion operation.

摘要： PURPOSE: To provide a combustion apparatus capable of dealing with both of production of CO gas and leakage of live gas of fuel gas. CONSTITUTION: Temperature of a CO sensor 20 for detecting CO concentration in waste gas is controlled to a temperature where CO gas and hydrocarbon(HC) can be detected whereby the CO sensor 20 can detect both of the CO gas and the HC. An HC/CO discrimination unit 26 incorporates therein a detection signal from the CO sensor 20 and a discrimination signal between combustion operation and interruption operation of an apparatus from a combustion discrimination unit 24, and decides the detection signal of the CO sensor 20 during the combustion operation to be a CO concentration detection signal while deciding that during interruption of combustion to be an HC concentration detection signal. When the HC detection signal is outputted exceeding a reference value, gas leakage safety means 43 interrupts a gas leakage safety valve 44 interposed in a fuel gas introduction part to the apparatus.

摘要： PURPOSE: To attain a clean combustion in which a less amount of production of nitrogen oxide and CO gas in produced. CONSTITUTION: A burner device 4 for a hot water feeding device is formed such that a lean burner for injecting pre-mixed gas of a low concentration and a rich burner for injecting pre-mixed gas of a high concentration are arranged while being adjacent to each other. A gas discharging side of a main body 2 of a combustion equipment is provided with a CO sensor 13 and a hydrocarbon(CHn) sensor 23 so as to detect a CO gas concentration and CHn concentration in the discharged gas. When the CO gas concentration becomes not less than a present CO concentration, a rotation of a combustion fan 5 is decreased after the CHn concentration reaches the pre-set reference CHn, and in turn when the CHn concentration does not reach the pre-set reference CHn, the rotation of the combustion fan 5 is increased. An amount of air supplied from the combustion fan 5 to the burner device 4 is controlled under this controlling operation so as to prevent a CO concentration in the discharged gas from exceeding a reference CO concentration.

摘要： PROBLEM TO BE SOLVED: To provide a hot air heater for releasing air into a room after burning fuel with room air and diluting combustion exhaust gas with the air and its control method, securing fresh air consistently in the room during heating operation. SOLUTION: The hot air heater comprises a detecting element 14 for outputting voltage corresponding to the temperature of flames 12 from a gas burner 10 at a predetermined position, to the flames 12 whose temperature is lower as the concentration of oxygen in air supplied to the gas burner 10 for burning fuel is lower. Furthermore, it has a control part 24 for outputting a command which issues a first warning for promoting the ventilation of the room when voltage output from the flame temperature detecting element 14 is lower than a first threshold value and for outputting a command which stops the first warning when the output voltage is not lower than the threshold value after the first warning, and an output part 22 for issuing the first warning in accordance with the command and then stopping the first warning.

摘要： PROBLEM TO BE SOLVED: To reserve service water without needing a labor, for example, during limitation of a water feed time, by providing a water filling mode wherein water is fed without being heated. SOLUTION: Assignment of a water filling mode and indication of operation starting are effected from a service station 2 and a CPU 11 of a gas hot water feeder 1 is operated based on the assignment and the indication. A feed water solenoid valve 13 is first opened and it is decided whether or not an assigned mode is a water filling mode. When it is not the water filling mode, an ignition sequence to ignite a gas burner 12 is executed and when it is the water filling mode, the ignition sequence is not executed. Since the assigned mode is now the water filling mode, the gas burner 12 is not ignited and water fed through a heat-exchanger 14 is water not heated but left as it is, and the water is reserved in a bath tub. When the level of water reserved in the bath tube attains a target water level, the feed water solenoid valve 13 is closed and it is decided whether or not an assigned mode is a water filling mode. When it is not the water filling mode, a gas burner 12 is fire-extinguished.

摘要： PROBLEM TO BE SOLVED: To reserve service water without needing a labor when a water feed time is limited and to perform sanitary management of reserved service water by providing a service water tank to receive and reserve service water through an auxiliary tank. SOLUTION: During pouring of service water in a service water tank 7, valves B and C are opened, valve A and D are closed, and ignition of the burners of heat-exchangers 4 and 5 is not carried out. Thereby, water in an auxiliary tank 6 flows in the service water tank 7 under gravity of water in the auxiliary tank 6. During operation to fill with hot water from the service water tank 7, the valves A and C are opened and the valves B and D are closed, and the burner of the heat-exchanger 5 for a bath is ignited. A pump P is driven, and through drive of the pump, water in the service water tank 7 flows in an auxiliary tank 6, and water in the auxiliary tank 6 flows in a piping 3 for a bath through a check valve E and the valve A. The water is pumped up by the pump P and heated by the heat-exchanger 5 for a bath, and poured in a bath tub through a piping H to fill a bath tub with hot water.
