Abstract
Official abstract text for this publication.
A burner has: a combustion plate part through which air-fuel mixture is ejected; and a flame rod which lies opposite to a portion of the combustion plate part. The combustion plate part is constituted by: a burner frame in a shape of a picture frame; a metal-fiber knit which covers an opening enclosed by the burner frame; and a distribution plate which has formed therein a multiplicity of distribution holes and which sandwiches the metal-fiber knit between the burner frame and the distribution plate so that the air-fuel mixture is ejected from the opening through the distribution holes and the metal-fiber knit. Flame holes for ejecting the air-fuel mixture are formed in a portion of the burner frame, and the flame rod is disposed so as to lie opposite to that portion of the burner frame which has formed therein the flame holes.
First claim
Opening claim text (preview).
The invention claimed is: 1. A burner comprising: a combustion plate part through which air-fuel mixture is ejected; and a flame rod which lies opposite to a portion of the combustion plate part, wherein the combustion plate part is constituted by: a burner frame in a shape of a picture frame; a metal-fiber knit which covers an opening enclosed by the burner frame; and a distribution plate which has formed therein a multiplicity of distribution holes and which sandwiches the metal-fiber knit between the burner frame and the distribution plate so that the air-fuel mixture is ejected from the opening through the distribution holes and the metal-fiber knit, wherein flame holes for ejecting the air-fuel mixture are formed in a portion of the burner frame, and wherein the flame rod is disposed so as to lie opposite to that portion of the burner frame which has formed therein the flame holes. 2. The burner according to claim 1 , wherein the burner frame has partly formed therein a protruded part which protrudes into the opening, and wherein the flame holes are formed in the protruded part. 3. The burner according to claim 2 , wherein the protruded part is constituted by a separate part which is independent of, but which is attached to, the burner frame. 4. The burner according to claim 1 , wherein the flame rod is provided with: a main body portion lying opposite to that portion of the burner frame which has formed therein the flame holes; and an extension portion which extends from the main body portion inward of the opening, and wherein the extension portion is further away from the combustion plate part than is the main body portion.
