摘要： During the heating of glass melting furnaces having a combustion chamber with regenerators for preheating oxidation gases, with port necks that open into the combustion chamber, with primary burners and with secondary burners that are installed in a cascade arrangement relative to the primary burners, the secondary burners are operated as cascade burners with a relatively low proportion of the fuel, the secondary fuel. Flames are thereby created in over- and sub-stoichiometric conditions and the flame gases formed are mixed with one another so that the complete combustion process in the combustion chamber is more or less stoichiometric. The secondary fuel is supplied by the secondary burners to a step, installed in the port neck. In order to prevent or reduce soot and graphite deposits in the step without increasing the nitrogen oxide content in the furnace waste gases, a secondary oxidation gas is blown into step during the firing phase of each port neck in addition to the primary oxidation gas preheated in the regenerators that flows over the step. If significant deposits of carbon material and/or temperature problems occur, then in a similar way an oxidation gas can be blown in during the exhaust phase for the furnace waste gases of each port neck when the secondary burner is switched off.
