Abstract

The gas burner according to the invention has a burner chamber housing, a mixing pipe connected to the burner chamber housing for supplying a gas/air mixture, a burner plate made of fibrous material and attached to the burner chamber housing at edge regions of the burner plate, a blower for supplying air to make the gas/air mixture, and advantageously an ignition device, a safety device and a temperature monitoring device. A central region of the burner plate is advantageously directly or indirectly connected to a corresponding central region of the burner chamber housing to suppress burner plate vibration during start-up of burner operation to prevent sound generation during the start-up and minimize the pressure drop in the burner chamber. In a preferred embodiment a recessed portion formed in a middle region of a base plate of the burner chamber housing is shaped to contact on a central region of the burner plate and a temperature-resistant adhesive is used to connect the burner plate and the recessed portion of the burner chamber housing.
