    摘要： A premix gas burner comprises a metal plate and a fiber based burner deck. The metal plate comprises a perforated section and a flange provided along the full circumference of the metal plate. The perforated section comprises a plurality of perforations. The fiber based burner deck covers the perforations of the perforated section; such that when premix gas is supplied to the premix gas burner, the premix gas flows through the perforations of the perforated section of the metal plate and through the fiber based burner deck to be combusted at the other side of the fiber based burner deck. The perforated section contains a central segment and four side segments. An edge of each of the four side segments contacts the edge of the central segment. The side segments are connected to each other via ribs. Each of the four side segments is connected to the central segment via a curved rib.

    摘要： A Heat exchanger element comprises a combustion chamber for the generation of hot gas; a meandering water flow channel for the flow of water to be heated; and two metal walls delimiting the water flow channel, for exchanging heat between the hot gas and water flowing through the water flow channel. The water flow channel is provided for water flow in counter direction to the flow of hot gas. The water flow channel comprises a number of consecutive parallel straight segments. The water flow channel comprises at least three U-turns which are each connecting two consecutive straight segments separated by an intermediate wall. At least one of the intermediate walls has one or a plurality of through openings.

    摘要： The invention provides a cylindrical premix gas burner (100) which is comprising a perforated metal plate as cylindrical burner deck (110). The cylindrical premix gas burner (100) is delimited by an end cap (118). An inlet disc (130) is provided for the supply of a premix of combustible gas and air into the burner. The premix gas is to be burned on the outside of the cylindrical burner deck (110) after the premix gas has flown through it. The inlet disc (130) is comprising a plurality of perforations for supplying premix gas supply into the burner. The inlet disc is having a centre point (150), which is where the central axis of the cylindrical premix gas burner (100) crosses the inlet disc (130). The inlet disc (130) is not permeable to premix gas at least within a circle with a diameter of at least 8 mm around the centre point (150).

    摘要： A gas burner (10), preferably a premix burner, comprising a support (12) which has a central gas inlet port for supply of gas into a gas supply chamber. The gas supply chamber is enclosed by a perforated metal plate (22). The perforated metal plate is connected at the bottom to the support through a base section. The perforations in the perforated metal plate provide a burner deck (20). The burner deck has an overall porosity which is equal to or lower than 11%. The present invention also provides use of this burner, e.g. in heat exchangers.
