ABSTRACT:
The present invention relates to a method for initiating the preheating of pulverous materials in a tubular heat exchanger prior to their introduction into a melting furnace, with particular application to the recycling of all of the vitrifiable starting materials through the heat exchanger to eliminate moisture therefrom prior to delivery to a tank furnace for glass making to raise its entry-level temperature and improve furnace efficiency. The method involves rapidly recirculating all of the moisture-containing pulverous glass batch material through the open-ended tubes of a tubular sheet exchanger to heat the same and collect and remove moisture therefrom prior to initiation of delivery of any of the glass batch material in preheated condition to the glass melting furnace. The subject invention, as hereinafter described, is of particular utility to the glass industry, but it is to be understood that it is also applicable to other types of preheaters and furnaces.
