Patent ID: 8821154

Claim:
A combustion apparatus, comprising: combustion means that generates flame by combustion; air supply means that supplies air to the combustion means; flame current detecting means that is set at a certain detection position and detects a flame current value included in the flame which is generated by the combustion means; flame detecting means that detects whether there is the flame or not in the combustion means; determination means that executes a determination process of a distribution that includes the flame current value detected by the flame current detecting means when the flame detecting means detects the flame; and control means that, when a current value in the distribution that includes the flame current value is higher than a current value in a distribution which is set as normal values, outputs a control command to increase a supply of the air by the air supply means, and that, when the current value in the distribution that includes the flame current value is lower than the current value in the distribution which is set as the normal values, outputs a control command to decrease the supply of the air by the air supply means, based on a determination result by the determination means.
