Claims

[Scope of claims for utility model registration] (1) Equipped with a fuel supply device and a combustion blower,
In a combustion device that premixes fuel supplied from the fuel supply device with air in an amount equal to or greater than a theoretical combustion air amount and combusts the mixture, the amount of air is reduced to an amount smaller than the theoretical amount of combustion air during at least one of ignition and extinguishing. A combustion device characterized in that it is provided with means for causing. (2) The combustion device according to claim 1, wherein the amount of air during ignition or extinguishing is 0.7 to 0.8 times the theoretical combustion air amount.
