Abstract

Abstract PURPOSE: To lower the temperature of burner element by a construction wherein a large number of slit shape secondary air holes and slit shape flame holes are disposed inturn in an array at flame hole parts. CONSTITUTION: At the center of the burner element 41 is provided a secondary air passage 42, at the left and right portions of which are disposed in an array the flame hole parts 43. At the flame hole parts 43, a large number of slit shape secondary air holes 44 and slit shape flame holes 45 are disposed in turn in an array.
