Batch preheating on glass melting furnaces

Abstract

The preheating of the raw materials with the flue gases leaving the air preheater can be a powerful tool to save energy and to increase the pull of a glass melting furnace. In the first part, this work deals with the magnification of the pull of glass melting furnaces from a theoretical point of view. In the second part, the results of heat balance measurements on glass melting furnaces equipped with a batch preheater are given. The measured results are compared with calculated results. Α good agreement of theoretical and measured results is found.
