Heating device for a combustion chamber with locally variing heating power

摘要

The heater includes an electric heating element constituting a heater for heating a surface (21) of the combustion chamber. An ignition zone (26) is heated to an ignition temperature lying above the temperature of the heating surface (21). The ignition zone is heated by the heating element. The heating element comprises a spatial distribution of heating power that corresponds to the temperature distribution of the heating surface and the ignition zone.
