Abstract
A cooking station for gas ranges whose burner works with super-stoichiometric combustion air premixing. The burner head arranged in a burner tray is connected with a mixing pipe via a ceramic insulating ring. Between the burner head bottom and the burner head lid with the flat topside, we have two perforated flame opening rings which are arranged concentrically with respect to the burner axis, which are resistant to heat and which are resistant to oxidizing and reducing atmospheres. The perforation of the inner flame-opening ring is so dimensioned that the flames cannot backfire. Below the burner tray there is arranged a reflector. The cooking station can be covered with a glass ceramics plate. The invention achieves stable flame performance, perfect combustion, and waste gas poor in harmful substances at nominal load and at small adjustment heat load within a vast utilization field of gases with differing Wobbe indexes as well as a start-up cooking efficiency improvement compared to known burners.
