Abstract

Während der Zündphase wird der Verdampfungsbrenner nur von einem minimalen Luftstrom durchsetzt, gleichzeitig wird ein Brennkammerbereich durch eine Glühkerze mit hoher Leistung erhitzt. Sodann wird die Brennstoffzufuhr mit sehr schwacher Förderleistung eingeschaltet, während gleichzeitig der Luftdurchsatz in der Brennkammer erhöht wird. Nach dem Zünden des Brennstoffes in der Brennkammer wird die Glühkerze ausgeschaltet, außerdem werden die Brennstoffzufuhr sowie der Luftdurchsatz bis auf die Werte für normalen Heizbetrieb erhöht.

Figure 00000001
During the ignition phase, the evaporative burner is only penetrated by a minimal air flow, at the same time a combustion chamber area is heated by a glow plug with high output. The fuel supply is then switched on with a very weak delivery rate, while at the same time increasing the air throughput in the combustion chamber. After igniting the fuel in the combustion chamber, the glow plug is switched off, and the fuel supply and air flow are increased to the values for normal heating operation.
