<p>PURPOSE:To improve the thermal efficiency of a glass smelting furnace furnished with a regenerator or a recuperator, by using the hot gas exhausted from the smelting furnace and the cooling furnace for the preheating of the combustion air of the smelting furnace and the raw materials of the glass. CONSTITUTION:Hot gas 5 exhausted from the glass smelting furnace 1 is introduced into the regenerator 3, heated by heat exchange, and combined with the hot gas 5' exhausted from the cooling furnace 1' for cooling the molten glass to a temperature suitable for the forming operation. A part of the mixed hot gas 5'' is sent to the glass cullet preheater 15 to preheat the raw material glass cullet. The remaining part of the mixed gas 5'' is introduced into the ceramic sphere preheater 8 to heat the ceramic spheres used as the heat medium. The heated ceramic spheres are supplied to the secondary air preheater 9 and the rotary heat exchanger 10 and utilized for the preheating of the secondary air 4 of the smelting furnace 1 and for the heating of glass batch 16 used as the glass raw material.</p> |
