Daily fluctuations in atmospheric pressure (air density) are monitored by an atmospheric pressure sensor, and control parameters are corrected based on the measured atmospheric pressure value, thereby achieving combustion in an optimum state.
Fig. 1 is a schematic block diagram showing a structure of a gas combustion apparatus according to an embodiment of the present invention.
As shown in fig. 1, the gas combustion device 100 of the present embodiment includes an exterior part 101 and a combustion control board 102. The exterior portion 101 is, for example, an exterior case. The combustion control substrate 102 is disposed inside the exterior portion 101 and controls combustion of gas. The combustion control board 102 controls the combustion of the gas, and includes, as control parameters, the fan rotation speed and the opening degree of the gas proportional valve. The air quantity provided for the burner is controlled by controlling the rotating speed of the fan, and the gas quantity provided for the burner is controlled by controlling the opening degree of the gas proportional valve.
As shown in fig. 1, the gas combustion device 100 of the present embodiment further includes an operation unit 103, an operation substrate 104, and an air pressure sensor 105. The operation unit 103 is disposed in the exterior unit 101.

The operation board 104 and the combustion control board 102 are connected so as to be able to communicate with each other. In the example shown in fig. 1, the air pressure sensor 105 is disposed on the operation substrate 104. However, the air pressure sensor 105 may be disposed on the combustion control board 102 instead of the operation board 104.
