Abstract:
A combustion apparatus includes a burner having a sheet-metal combustion plate which covers an open surface of a burner body; and a combustion box having a connection flange part to be coupled to a body flange part enclosing the open surface of the burner body, and is equipped with a cooling means for cooling the combustion box, an arrangement is made that overheating of the burner body due to heat transmission from the combustion plate can be prevented, even without enhancing thermal insulation performance of a packing to be interposed between a combustion plate flange part and the body flange part. The connection flange part is kept in direct contact with the combustion plate flange part and, coupled to the body flange part. The packing is provided with: a combustion plate seal part to be pressed under pressure against the combustion plate flange part; and a combustion box seal.

Claim (Index 1):
A combustion apparatus comprising:\n a burner made up of a burner body which is supplied therein with air-fuel mixture, and a sheet-metal combustion plate which covers an open surface of the burner body and has an ejection part for the air-fuel mixture; a combustion box which has, at one end, a connection flange part adapted to be coupled to a body flange part enclosing the open surface of the burner body, and which contains therein a heat exchanger; and cooling means which is disposed in that portion of the combustion box which lies between the burner and the heat exchanger, thereby cooling the combustion box; wherein a packing is interposed between the body flange part and a combustion plate flange part on a circumference of the combustion plate which protrudes outward beyond an inner circumference of the body flange part; and wherein the connection flange part is coupled to the body flange part by a fastening operation in a state in which the connection flange part is in direct contact with the combustion plate flange part, and the packing has a combustion plate seal part which is compressed, as a result of the fastening operation, between the combustion plate flange part and the body flange part.
