ABSTRACT:
A method and apparatus for efficiently preheating glass batch utilizing waste gas from a glass melting furnace is provided. In a method and apparatus for preheating glass batch utilizing hot waste gas discharged from a glass melting furnace before glass batch is inputted thereto, a heat exchanger 30A for heating heat medium gas located in a waste gas flue 12A and a glass batch preheater 20A located on the upstream side of a batch input port 11A are communicated by means of an inline duct 31A and an outline duct 32A to form a heat medium gas circulating circuit. Clean gas having heat radiation intensity in the infrared ray wavelength range such as carbon dioxide or water vapor is enclosed in the circuit as the heat medium and is forced to endlessly circulate and go round in the circuit by a blower 33A located in the outline duct thereby to preheat glass batch and, at the same time, to cool hot waste gas to appropriate temperature.
