Definitions
- the catalyst is located between the fuel supply device and the ignition device, or - in other words: fuel supply and ignition device are located on opposite sides of the body used for flameless oxidation.
- the still cold, ie inactive, catalyst must be filled with fuel or fuel mixture at least up to the ignition system before the oxidation reaction can be started by raising the temperature on the outer edge of the body.
- the flameless oxidation spreads from the heated point in the direction opposite to the direction of flow of the fuel or fuel mixture.
- butane or isobutane fuel for igniters of tobacco products; Therefore, some characteristic values for the illustration of the method or the device are given here.
- the electrode 22 of the piezo hammer mechanism is at the same potential as the electrically conductive base body 20 and the metallic tube 15; the piezo hammer mechanism is actuated by axial displacement of the tube by the stroke 21, as a result of which a discharge spark is produced between the electrode 23 and the inside of the tube 15.
- the inside of the tube 15 can have a counter electrode (not shown).
- the discharge spark ignites the fuel mixture in the area 3 between the insulation 17 and the catalytic converter 2, which causes the temperature of the part of the catalytic converter facing the mixture supply to rise above the light-off temperature.
- the catalytic oxidation set in there subsequently spreads rapidly in the rest of the catalyst along the pipe 15 because of the heat development associated therewith.
