    • An improved method preheating cullet and glass batch together for use as feedstock for a glass furnace. The method uses a preheater including a separator and a heat exchanger. The heat exchanger is a direct contact raining bed in which large particles in the feedstock are heated by hot gases as the particles flow down by gravity and fine particles become entrained with the hot gas flow. The separator removes the fine particles entrained in the hot gases and remixes preheated the fine particles with the preheated cullet. Preheater systems are described in which the hot gasses are provided by the glass furnace exhaust, by a separately fired heater, by a separately fired heater combined with the glass furnace exhaust and by a separately fired heater with exhaust gas recirculation.
    • 一种改进的方法将碎玻璃和玻璃批次预热用作玻璃熔炉的原料。 该方法使用包括分离器和热交换器的预热器。 热交换器是直接接触的下沉床,其中当颗粒通过重力流下时,原料中的大颗粒被热气体加热,细颗粒与热气流一起被夹带。 分离器除去夹带在热气体中的细颗粒,并用预热的碎玻璃预混合细颗粒。 描述了预热器系统,其中热气体由玻璃炉排气,单独燃烧的加热器,通过与玻璃炉排气组合的单独燃烧的加热器和通过具有废气再循环的单独燃烧的加热器提供。
