Combustion apparatus

Abstract

The combustion apparatus includes a burner configured to generate flame, an ignition section configured to generate spark for igniting the burner, a flame detection section configured to detect the presence or absence of the flame of the burner, and a flame determination section configured to determine, based on a detection result of the flame detection section in a preset determination period, whether or not the flame is generated at the burner. When a predetermined condition is satisfied based on the detection result of the flame detection section in the determination period, the flame determination section determines that the flame is generated. The ignition section generates the spark across a particular period, in which the predetermined condition is not satisfied, of the determination period, and does not generate the spark in the remaining period of the determination period.
