A combustion membrane (14) for a gas burner (2) comprises a fabric or mesh (21) of interlaced metal threads (22), having two opposite interlacing surfaces (19, 20) which form a combustion surface (19) and an inner surface (20) of the fabric/mesh (21), respectively, wherein the metal threads (22) are formed by twisted metal fibers (22) to form a yarn and: the individual metal fibers (22) are shorter than the yarn (22) formed therefrom, and free ends (22″) of the metal fibers (22) protrude divergently from the yarn (22) along its longitudinal extension and make the yarn (22) hairy, and the metal thread (22) is a yarn (22) of mass per length in the range from 0.8 g/m to 1.4 g/m.

An object of the present invention is to realize a combustion control device that reduces, when a pressure within a mixer is rapidly increased at the time of ignition of the combustion control device, the transmission of the temporarily increased pressure to a pressure sensor, that brings the pressure sensor into a non-operated state and that thereby can continue combustion in the combustion control device. Hence, a combustion control device is provided that includes: a combustion chamber which has a heat dissipation disc on a front surface and within which a combustion room is formed; a burner which is attached to the combustion chamber; a mixer which mixes a gas supplied to the burner with air; and a pressure sensor which is connected to the mixer through a pressure passage, where a pressure propagation delay means which reduces transmission to the pressure sensor caused by a temporary pressure increase within the mixer is provided partway along the pressure passage.

High intensity combustion and low intensity combustion are carried out together, to stabilize flames and to hold down the emission of carbon monoxide. An air-fuel mixture outlet member (back plate) that includes a single or a plurality of outlet(s) (air-fuel mixture outlet(s)) out of which an air-fuel mixture (GA) flows is include, and a metal fiber knitting body (metal knit) that covers the air-fuel mixture outlet member is included. Therefor, the air-fuel mixture, which is made to flow out of the outlet(s), passes through the metal fiber knitting body (metal knit) and is combusted, a flame of low intensity (flame) is generated together with a flame of high intensity (flame) by combustion of the air-fuel mixture, and the flame of low intensity holds the flame of high intensity.

A totally aerated combustion burner has: a burner body which is supplied therein with air-fuel mixture; and a combustion plate part which covers an open surface of the burner body. The combustion plate part is constituted by: a burner frame in a shape of a picture frame; a metal-fiber knit which is disposed to cover, from a burner-body side, 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. Only the metal-fiber knit is spot-welded to that opening peripheral part of the burner frame which is positioned on a same surface as the opening. The distribution plate is spot-welded to that portion of the burner frame which is offset from the opening peripheral part toward the burner-body side.

A combustion apparatus has a burner including a burner body and a combustion plate, as well as a combustion box. A combustion plate flange part projects outward beyond an inner rim of a body flange part and beyond an inner rim of a combustion box flange part. A packing has a portion interposed between the combustion plate flange part and the body flange part, and a portion interposed between the combustion box flange part and the body flange part outside an outer rim of the combustion plate flange part. A distribution plate having formed therein a multiplicity of distribution holes for introducing the air-fuel mixture toward an air-fuel mixture ejection part is provided with a distribution plate flange part so arranged as to come into direct contact with that portion of the combustion plate flange part which is positioned inside an inner rim of the packing.

A combustion apparatus has a burner including a burner body and a combustion plate, as well as a combustion box. A combustion plate flange part projects outward beyond an inner rim of a body flange part and beyond an inner rim of a combustion box flange part. The combustion box has, on a perimeter of one end, the combustion box flange part, adapted to be connected to the body flange part enclosing an open surface of the burner body. The combustion plate is provided with an inside projection which is erected, by bending, toward the body flange part so as to face the inner rim of the packing such that, in a state in which the combustion box flange part is connected to the body flange part, the outside projection and the inside projection are in contact with the body flange part.

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.

A burner has: a combustion plate part for ejecting air-fuel mixture; and a flame rod which lies opposite to a portion of the combustion plate part which has a picture-frame-like burner frame; a metal-fiber knit which covers an opening enclosed by the burner frame; and a distribution plate which has formed therein distribution holes and which sandwiches the metal-fiber knit between the burner frame and the distribution plate through the distribution holes and the metal-fiber knit. The flame rod has: a rod base part which lies opposite to a portion of opening peripheral part of the burner frame which is positioned on the same surface level as the opening; and a rod main body part which lies opposite to a portion of the metal-fiber knit. The distance between the rod base part and the opening peripheral part is made smaller than the distance between the rod main body part and the metal-fiber knit.

The invention relates to a burner with surface burning, which comprises a burner head (12) having a housing (14), which has a supply (18) for a fuel-air mixture upstream and has a fabric membrane (16) downstream on an outlet side and comprises a flame flash-back barrier (17), which is arranged upstream of the fabric membrane (16) at a distance to this, wherein at least the fabric membrane (16) and the flame flash-back barrier (17) are arranged by at least one releasable connection element (54) which engages with a receiving region (47) in the housing (14).
