A horizontally-fired burner system includes, in a combustion volume, a distal flame holder, the distal flame holder including a plurality of columns each formed from a respective plurality of refractory tiles, and a fuel and combustion air source configured to output a flammable fuel and air mixture toward the distal flame holder. The distal flame holder is configured to hold a combustion reaction adjacent to each of the plurality of columns.

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 includes a distal flame holder, first and second fuel nozzles, a fuel and oxidant source, and a mixing tube disposed upstream from the distal flame holder. Fuel emitted from the first fuel nozzle mixes with oxidant from the oxidant source to form a fuel and oxidant mixture to support combustion in the distal flame holder. A non-reactive fluid source such as recirculated flue gas provides a non-reactive fluid for dilution of the fuel and oxidant mixture to prevent flashback.

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 proposes a method for the flame signal detection by means of an ionization electrode (15) protruding into a combustion zone of a burner, comprising the steps: detecting a first signal, which is dependent on an ionization current flowing off the ionization electrode (15), generating a second signal which has a predetermined periodic course, generating a third signal by adding the first signal and the second signal, comparing the third signal with a first threshold value and generating a fourth signal on the basis of the comparison of the third signal with the first threshold value, comparing the third signal with a second threshold value different from the first threshold value and generating a fourth signal on the basis of the comparison of the third signal with the second threshold value, and determining an operating variable of the burner on the basis of at least one of the fourth signal and the fifth signal. The invention additionally proposes a corresponding device for the flame signal detection.

A burner assembly (40) for providing a flame and combustion gas to a plurality of inlets includes a support member (70) having a back surface and an inner surface. An elongated opening (72) is formed in the support member. A burner (74) is connected to the support member adjacent the opening and extending upstream from the back surface. The burner is arranged in fluid communication with the plurality of inlets. An interior surface of the burner is contoured to direct flames generally inwardly.

A burner has a housing on which a combustion tube is arranged, wherein the combustion tube has an opening at the end averted from the housing, wherein a mixing element is provided in the combustion tube, and the space between the mixing element and the opening forms a combustion chamber, wherein the housing has at least two mutually separate channels which open out in the mixing element, wherein gases flow through the channels and the mixing element, and mixing of the gases takes place for the first time in a combustion chamber, wherein the mixing element is produced in an additive manufacturing process and has at least two separate intermediate channels which branch in the direction of the combustion chamber in a flow direction.

Various embodiments include a combustion apparatus. An example apparatus includes: a burner; a side duct; and a feed duct. The side duct comprises an inlet, an outlet, and a mass flow sensor between the inlet and the outlet of the side duct. The mass flow sensor is configured to detect a signal corresponding to an amount of flow of a fluid through the side duct. The side duct comprises a first portion and a second portion. The first portion of the side duct comprises the mass flow sensor. The first portion of the side duct is arranged within the feed duct.

The present invention relates to a burner head of a burner for a gas cooktop, a burner, and a gas cooktop. The burner head includes a plurality of supports, where each support includes a support surface for supporting a cooking utensil, the support is further provided with a plurality of gas ports from which gas flows out and forms a flame, and each support has a first working position and a second working position. When the supports are in the first working position, the burner head has a flat upper surface and the support surfaces of the supports constitute the upper surface; and when the supports are in the second working position, the burner head has a concave surface, and the support surfaces of the supports constitute the concave surface. In the present invention, the shape of the burner head is changeable, so as to adapt to cooking utensils having different bottom outlines.

A burner includes an atomizing chamber, a flame tube in front of the atomizing chamber adapted to direct combusting fuel introduced by the atomizing chamber along an interior of the flame tube, and a controller. The controller is programmed to independently control rate of fuel flow to the atomizing chamber, rate of atomizing air flow to the atomizing chamber, and rate of combustion air to the flame tub. The controller is also programmed to perform operations including regulating, based on output of a gas sensor, at least the rate of combustion air to the flame tube to substantially maintain a first predetermined amount of excess air in the flame tube.
