APPARATUS FOR MEASURING TEMPERATURE OF GLASS MELTING FURNACE

摘要

Disclosed is an apparatus for measuring the temperature of a glass melting furnace. The apparatus includes: a generally barrel-shaped glass window part arranged in a temperature measurement hole of the glass melting furnace so as to communicate therewith and to form a see-through hole extending to the outside of the glass melting furnace, the see-through hole being provided with a transparent glass window; and a camera part containing a thermal image camera arranged so as to photograph the inside of the glass melting furnace through the glass window part, wherein the glass window is positioned at the side of the see-through hole opposite to the glass melting furnace. This apparatus enables the see-through hole to be supplied with a cooling gas in the upper and the lower direction so as to prevent the surface of the glass window from being covered with fumes and to confine heated gases and fumes to the glass melting furnace.
