Claims

[Claims for Utility Model Registration] (1) A flame port plate having an annular flame-forming surface, and a flame port provided on the flame port plate for ejecting a mixed gas of fuel and primary air to form a flame. , an ejection tube attached to the tip of the secondary air passage formed in the center of the burner port plate and having a secondary air outlet on the peripheral wall; and an ejection tube located approximately upstream of the secondary air from the ejection tube A combustion device comprising: an ejection hole that ejects secondary air; and a current-changing surface that causes the secondary air ejected from the ejection hole to be transformed in a radial direction along the flame forming surface. (2) The combustion device according to claim 1 of the utility model registration, characterized in that the flow changing surface connects the burner port plate and the ejection tube.
