A refiner for a glass melting system includes a housing that defines a refining chamber and a refining well. The refining chamber contains a refining glass bath, which is fed by a flow of incoming glass that flows through the refiner well. To impede molten glass within the refining glass bath from backflowing into the refiner well, the housing of the refiner includes a backflow restrictor wall that projects upwardly from a floor of the refiner and elevates a refiner well outlet above the refiner floor, and/or the refiner well outlet is defined at least partially by the refiner floor and the refiner well is provided with a rectangular cross-sectional shape that is constant from the refiner well outlet down through the refiner well at least part way to a refiner well floor.

The invention relates to a method for heating flowable molten glass in a feed channel which is enclosed by lateral walls and a cover and into which a plurality of fuel lances and oxidizing agent lances that are mutually spaced in the flow direction of the molten glass open above the molten glass, fuel or an oxidizing agent being supplied through said lances and being brought into reaction with each other in the feed channel. The invention is characterized in that in order to combust the fuel with the oxidizing agent, a flame is produced in front of the opening of each fuel lance, said flame being designed such that adjacent or opposite flames do not contact one another.
