PURPOSE:To stabilize flame, by a method wherein a burner device consists of a burner having air passages at the center and the outer periphery and a blower, and a distributing means for uniformly feeding gas to a mixing chamber and a feed port for feeding the premixing air in a distributing gas through the air passage are provided. CONSTITUTION:A burner consists of a burner 9 having a plurality of holes 10 for premixing air formed in a ring shape, a dispersing air hole 11 for inner periphery, a dispersing air hole 12 for outer periphery, and an air passage 13 for dispersing fuel, and a blower 7 for feeding the air for combustion to the burner. With a number of slit flame holes 14 bored in the upper part, the interior forms a mixing chamber 15, and a uniform chamber 19 for averaging the gas feed pipe 18 is formed. A number of pores 20 are uniformly distributed and bored to provide the burner with a means adapted to uniformly distribute and feed the gas, and a plurality of feed ports 21 for supplying a premixing air are uniformly bored at the entire periphery in the bottom part of the premixing chamber 15 to communicate them with the holes 10 for premixing air and with the air passage. |
