Hereinafter, with reference to the accompanying drawings for a preferred embodiment for achieving the above object of the present invention will be described in detail.

That is, Figure 2 shows a gas boiler (1) to which the present invention is applied, it is installed in a casing (Casing, 2) of the gas boiler (1) is a combustor for burning the gas to heat the hot water for heating or hot water ( 10), a water tank 20 for replenishing the heating circulating water, and a secondary heat exchanger exchanging heat through different paths with the heating water that has already been heated to heat the hot water coming from the outside with hot water ( 30) are constructed by combining with each other.

At this time, a burner group 12 including a plurality of burners is formed in the casing 11 of the combustor 10, and a primary heat exchanger 14 is installed in an upper direction thereof to prevent overheating and the water passes therethrough. The burner group 12 is heated, and a fan 13 for supplying combustion air is installed at the bottom of the combustor casing 11, and the burner group 12 is provided near the burner group 12. A spark plug 15 for ignition and a flame rod 16 for detecting ignition of the burner group are installed, and an exhaust unit 18 for discharging waste gas is provided on the upper surface of the combustor casing 11. ) Is formed through the case 2 of the gas boiler 1.

In addition, a gas pipe 50 for supplying gas is installed below the burner group 12, which includes two electromagnetic valves 51 and 52 for passing the gas at the time of energization and a proportional valve for adjusting the gas supply amount. 53 is provided from the upstream of the gas pipe 50 with respect to the gas supply path.

Meanwhile, the water tank 20 has a high water level sensor 21 for detecting the quantity of water in the water tank, an overflow pipe 22 for discharging excess water, and whether the water is empty or filled in the pipeline. Low water level detection sensor 32 to detect, the heating return pipe 24 is installed with a separator 23 for recovering the heating water rotated on the floor and the water supply pipe 25 for supplying water to the primary heat exchanger (14) ) Is provided with a circulation pump 26 for adjusting the circulation of water in the downward direction.

In addition, thermistor 1 (TH1) for detecting the temperature of the heated hot-water flowing out of the primary heat exchanger (14) and the temperature of the heating return for entering the heat exchanger for the primary heat exchanger (14) are detected. Thermistor2 (TH2) is attached to measure the temperature of each heating shaft water and heating return, and the flow switch (Folw Swith: FLS, 33) to detect the presence of water flow when cold water flows in from the outside of the gas boiler Water flows through the three-way valve 36 through the three-way valve 36 through the direct inflow pipe 34 and the water supply pipe 25 in which a mechanical automatic quantity control device is installed to obtain a stable temperature characteristic by passing a predetermined amount according to temperature.
