Combustion apparatus and method for combustion control thereof

A combustion control method, comprising:

• generating flame by combustion of combustion means;
• supplying air to the combustion means by air supply means;
• detecting, by a flame current detecting means set at a certain detection position, a flame current value included in the flame which is generated
• detecting whether there is the flame, which is generated by the combustion means, or not;
• and
• executing a determination process of a distribution that includes the flame current value detected by the flame current detecting means when the flame is detected;
• wherein 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, a supply of the air by the air supply means is increased, based on a determination result by said determining;
• and
• wherein 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, the supply of the air by the air supply means is decreased, based on the determination result by said determining.

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;
• determination means that determines a distribution that includes the flame current value detected by the flame current detecting means;
• 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,
• wherein the control means stops the combustion of the combustion means when the determination result is over a threshold level representing an exhaust blockage.
