摘要： The water heater has an upright water tank (1), an exhaust flue (3) extending through the water tank, a combustion chamber (2) arranged under the water tank, an atmospheric gas burner (5) in the combustion chamber and a complete pre-mixing gas/air supply system with outside gas and air intakes. The gas burner has a burner mat (7) with a pressure drop less than 5 to up to 45 Pa. The combustion chamber (2) is provided with an opening (2b), which is not sealed, but enclosed in a flame-blocking manner. The gas burner (5) is attached to a wall section (2a), which is mounted releasably on the: combustion chamber wall (W) over opening (2b) so that a gap of predetermined width is formed between the wall section and wall (W), which prevents backfire of flames into the surroundings but admits secondary air.

摘要： The gas-fired heater, especially a water heater, has an atmospheric gas burner (5) arranged within a nearly or completely closed combustion chamber (2) and associated with a premixing gas/air supply system (8) with a fuel gas feed nozzle (10). In order to avoid oscillations, which lead to sound waves and combustion instabilities, an oscillation-damping air supply chamber (11, 11′, 11″) is connected to the entrance (8a) of the gas/air supply system (8) for combustion air, within which the fuel gas feed nozzle is arranged. The air supply chamber (11, 11′, 11″) is provided with at least one air entrance (12, 12′, 12″). The air supply chamber can be box-like, duct-like embracing or extending around the combustion chamber or it can be a pipe with different diameter pipe sections.

摘要： The gas-fired heating apparatus, especially a water heater, has a combustion chamber (2a); an atmospheric gas burner (5) within the combustion chamber (2a); a combustion gas/air supply system (18) having an intake device (16) for combustion gas and primary air to be mixed with the combustion gas, which is arranged outside of the combustion chamber, and an oscillation-damping air supply chamber (11) provided with at least one air inlet (12), which is connected upstream to the intake device (16) and is constructed as a Helmholtz resonator to reduce noise and stabilize combustion. To provide sufficient primary air under adverse spatial conditions the air supply chamber (11) has an exterior wall (11′) and a pattern (13, 14) of perforations in the exterior wall, which are formed as additional air inlets for additional supply of the primary air.
