Title: Combustion apparatus
Inventor: NAGAHAMA TOMOHIRO
IPC: F23N5/24
Filed: 2018-10-15
Abstract: To provide a combustion apparatus capable of suppressing a stop state of a burner caused by a drift phenomenon of a CO sensor.SOLUTION: Fuel gas is burned by a burner, and a concentration of carbon monoxide included in combustion exhaust gas from the burner can be measured by a CO sensor. On the basis of the fact that a measurement value obtained by the CO sensor has exceeded a predetermined reference value, error stop processing for stopping the combustion by using the burner is executed. When the error stop processing is performed, after scavenging processing for discharging the combustion exhaust gas over a predetermined scavenging time by blowing air from a combustion fan is performed, zero point calibration of the CO sensor is executed. Thus, when the measurement value obtained by the CO sensor exceeded the reference value due to a drift phenomenon of the CO sensor, even if combustion by using the burner is resumed after the completion of the zero point calibration, the combustion can be continued without problems.SELECTED DRAWING: Figure 4
