초록

A glass melting furnace has a gas inlet positioned proximate to a charging section oxy-fuel combustion region to introduce gas into the region and to at least partially displace gas having a partial pressure of alkali vapor from the region, and optionally a gas outlet is adapted to provide an exit for a volume of furnace atmosphere. A method for reducing alkali vapor corrosion of glass furnace refractory structures includes providing a gas inlet proximate to the oxy-fuel combustion region; introducing a volume of gas from the inlet into the region, displ...

청구항

We claim: 1. A glass melting furnace having: an upstream melting zone; a downstream fining zone; a charging section in the melting zone; at least one oxy-fuel tired burner disposed in the melting zone proximate the charging section to provide an oxy-fuel combustion region; at least one gas inlet positioned proximate to the oxy-fuel combustion region to introduce a first volume of gas, having no or a dilute partial pressure of alkali vapor, into the oxy-fuel combustion region and at least partially displace a second volume of gas, optionally substantiall...
