If impurities, especially grease on the burner cover, come into contact during a cooking process, they burn because of the high temperatures and the gas burner is therefore difficult to clean.
  • the efficiency of the burner is not optimally used in such known gas burners. Due to the large coverage of the flames through the burner cover, they only reach a pot located above the gas burner at a considerable distance from the burner cap.
