Definitions
- the dome shape of the perforated metal plate is provided by deep drawing of a perforated metal plate.
- the dome shape extends into the mixing chamber when the inlet device 120 is mounted in the burner 100.
- the dome shape of the perforated metal plate 145 is provided by deep drawing of a perforated metal plate.
- premix gas is fed through the perforations 147 of the dome shaped perforated plate 145 of the inlet device 120 into the mixing chamber.
- the burner 100 comprises an end cap 180, which closes off the mixing chamber at the side opposite to the side where the inlet device is provided.
- the exemplary burner 100 of figure 1 is provided such that in use of the burner, the premix gas flows from the inlet device through the cylindrical burner deck without further passing a gas diffusing device.
- Cylindrical burners have been made with internal diameter D 82 mm and length L 588 mm of the burner deck.
- the burner deck was a perforated metal plate, with a blind zone with length L1 at the base of the burner deck equal to 23 mm.
- No gas diffusing device was used in the mixing chamber of the burner.
- Burner A was a prior art burner with a flat perforated plate inlet disk.
- Burner B was a burner according to the invention with a dome shaped perforated plate inlet disk, with a largest distance P 22 mm from the surface of the dome shaped perforated inlet disk to the plane of the surface of the inlet disk for mounting the burner into a heating appliance. Ignition of each of the burners was tested 10 times at four different air over gas premix gas ratios. The four different air over gas premix gas ratios are indicated by the C0 2 percentage in the combustion gas;
