PURPOSE:To reduce production of NOx, by a method wherein partitions, respectively limiting the supply of the air to each burner, are respectively mounted to combustion chambers. CONSTITUTION:The air, required and sufficient for combustion, is sucked through an air suction part 6 by means of gas injected to a mixture pipe 3 through a nozzle 4, and is burnt in a burner part (a flame port part) 5. The burner part 5 performs combustion in a combustion chamber 1 which is constituted entirely airtightly except an exhaust gas exhaust part. Plural burners are located in the combustion chamber 1, and a partition 2 is situated in the combustion chamber corresponding to each burner. The partition 2 serves to individually completely partition the burners 5 from each other so that one combustion chamber has one burner. By means of the partition 2, the flow of the air from the outside through a part except the air suction part 6 is shut off, and individual and independent combustion is effected by the burner, and this, even when a gas amount is desired to be throttled or the plural burners are operated in a flickering manner, prevents increase of an NOx amount, resulting in provision of excellent combustion. |
