ABSTRACT:
A method and apparatus for preheating material in a glass melting furnace is provided. An indirect heat exchanger is utilized in which exhaust gases from the glass melting furnace are directed, in a counter flow relation, to raw materials and glass cullet being fed into a glass melting furnace. A first conduit is connected to the heat exchanger to withdraw gases formed from the decomposition of organic matter present in the materials being preheated and the gases are directed by the conduit into the glass melting furnace where they are combusted. A second conduit may also be provided for extracting water vapor released from the preheated materials prior to decomposition of the organic material.
