Title:
A GLASS HEATING FURNACE WITH OPPOSING GAS STREAMS
Document Type and Number:
WIPO Patent Application WO/2005/115934
Kind Code:
A1
Abstract:
A glass heating furnace with opposing gas streams includes upper and lower furnace bodies, and at least one collector box is mounted respectively in them. Gas inlets and outlets are setup in the collector boxes, and jet flow boards are set at the gas outlets. The inlets of the collector boxes are connected with the exhaust port of a blower fan through pipelines. Gas heating devices are setup in the collector boxes. The gas inlet of the blower fan and its upper gas passages along with the exhaust port of the blower fan and its lower gas passages form a gas circulation loop together. Glass is heated in the heating furnace of the invention by the hot gas sprayed on its surfaces, so the deficiencies of low heating efficiency and long heating time can be effectively avoided when heating the glass with high reflectivity and transmissivity. The power of the heating devices can be expediently selected according to the temperature and the flow rate of the hot gas needed, in particular, the hot gas sprayed on the upper and under surfaces of the glass can be set to different temperatures to make the upper and under surfaces of the glass be heated uniformly and ensure the heating quality.
