    摘要： A gas premix burner is provided that comprises - a perforated plate, a woven wire mesh or expanded metal sheet; - a fiber based burner deck placed onto said perforated plate, woven wire mesh or expanded metal sheet; and - an ionization pen to measure the ionization current in the flame of the gas premix burner. The fiber based burner deck is thicker in at least part of the region where the ionization pen is located compared to other regions of the fiber based burner deck. The invention allows to use ionization current measurement for burner control over a broader load range of the gas premix burner.

    摘要： A cylindrical gas premix burner (100) is described that is comprising - a cylindrical burner deck (110), wherein the cylindrical burner deck (110) is comprising a metal plate, and wherein the cylindrical burner deck (110) has a perforated zone, the perforated zone being the part of the cylindrical burner deck (110) that is foreseen with perforations in the metal plate, - an end cap (115), - an inlet (112) for gas premix at the opposite side of the end cap (115). The perforated zone is comprising - seen along the axis of the cylindrical gas premix burners - at least three sections, wherein a first section (140) at the inlet, a third section (160) located towards the end cap, and a second section (150) located between the first section (140) and the third section (160). The porosity of the second section (150) of the cylindrical burner deck (110) is at least 50% higher than the porosity of the cylindrical burner deck (110) in the first section (140) and then the porosity in the third section (160). The cylindrical gas premix burner (100) can be used in combination with an ionization pen (190) for efficient control of the air to gas ratio over a broad load range of the cylindrical gas premix burner (100). The cylindrical gas premix burner (100) can e.g. be used in boilers or in instantaneous water heaters.

    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.
