PURPOSE:To achieve high load burning and improve assembly work by a method wherein the both end sides of a burner member fitted closely over the outside of a burner body are folded back and one end of a side air spouting plate is introduced on top of the inserted part and the other end is fixed to a burner case and the both ends of a center air spouting plate are closely introduced into the inserted parts installed between the burner members. CONSTITUTION:As for burning air, a part is mixed with fuel to make premixed vapor which is supplied to burner bodies 2, equalizing plates 2', and burner members 3 and the remaining greater part is supplied to an air chamber 9 as secondary air. After the premixed vapor is stream-smoothened by the equalizing parts 2', it is spouted into a burning chamber 1 from a number of flame holes installed in flame hole parts 3'. On the other hand, secondary air is made uniform by a baffle plate 10 and then reaches a center air spouting plate 4 and side air spouting plates 5 to be spouted into the chamber 1 from air holes 7. Then a part of secondary air passes through gaps 16 constituted by small projections 11 and is reduced in pressure to reach a flame holding air chamber 12 and is spouted into the chamber 1 from the both sides of the parts 3'. Therefore, fire flames have their fire flame base parts first stabilized by this flame holding air and the length of the fire flames is reduced to achieve high load burning.
