| 摘要 |
<p>The invention relates to a glass melting furnace heated by means of burners, in which at least 65%, and preferably at least 80%, of the combustion energy is produced by oxy-fuel combustion, the combustion gases at the outlet of the furnace being passed into a first heat exchanger (2) where air circulates, the air and the combustion gases being in distinct and separate circuits, the air heated in this first exchanger being passed into at least a second exchanger (4) intended for preheating the oxygen-based oxidant, the oxidant and the air circuiting in distinct and separate circuits, the air leaving this second exchanger being passed into a third exchanger (6) for the contactless preheating of at least one portion of the vitrifiable charge comprising raw materials and optionally cullet.</p> |
