Recent developments in the use of Austeel-Escher recuperators with high temperature furnaces

GT V01 1960 200-203

Although an experimental set-up about ten years ago had been used to give air preheats in excess of 600" C, the first applications of Austeel-Escher recuperators to glass furnaces were designed to give preheat temperatures of only about 500 to 550" C. As greater experience has been gained and the characteristics of high temperature steels have been better understood, together with their greater availability, recuperators have been used to give air preheats in the region of 700 to 800°C. Methods of obtaining these higher preheats are described and particular applications to glass fibre furnaces and unit melters are referred to. Austeel-Escher recuperators have been used extensively in the steel industry and reference is made to some installations for preheating both gas and air.
