PURPOSE: To increase a width of combustion and to reduce noise by forming to partition a plurality of mixing chambers by a partition wall under a burner port plate having many burner ports, providing air injection ports at the respective chambers, providing a gas supply unit for supplying excessively thick mixed gas, and providing gas concentrations of the respective chambers so as to be high at a central part and lower toward ends.

CONSTITUTION: A burner port plate 3 having many burner ports 2 is partitioned at a lower part to form a plurality of mixing chambers 5. An air passage 6 is disposed under the chambers 5, and the air is supplied to the chambers 5 through air injection holes 8 formed at a straightening plate 7. A gas supply passage 9 is connected to the chambers 5. Excessively thick mixed gas generated from a mixing chamber 10 formed on the way is supplied to the chambers 5. Gas concentrations of the mixed gases of the chambers 5 are so set as to be 1.0 or more at excess air ratio of a center and 1.0 or less at the ratio of an end to thickly and thinly burn on the plate 3 of upper surfaces of the chambers 5.
