Regenerative Schmelzwanne mit verminderter NOx-Bildung

摘要

The invention relates to a method for the operation of a glass melting furnace, in which the combustion gas heats up the combustion air in regenerators and the burners are arranged in two planes on both sides so that they can be switched over. A new method is characterised in that the burners in one plane (2) are operated under substoichiometric conditions and in the other plane (3) under superstoichiometric conditions and that the combustion gases are subjected, in a mixing zone, to afterburning under stoichiometric conditions.
