Abstract
A process for operating a burner fed with liquid fuel, in particular a vaporization burner of a heater in which, preferably, a motor vehicle add-on heater is involved. In this operating process, after the burner has been in steady state operation for a predetermined period, the fuel feed is briefly interrupted. The predetermined period of steady state operation of the burner is preferably about 5 to 20 minutes, while the fuel feed is interrupted for about 5 to 25 seconds. With this operating process, deposits on the burner can be reduced so that the service life of the burner can be considerably increased.
