Abstract

Ever since the famous Arab oil embargo, American industry has carefully reviewed its attitude towards energy consumption. Higher fuel prices and curtailments in fuel allotments have caused concern about fuel efficiencies. In industrial heat treating practice, energy savings can be successfully achieved by utilizing heat recovery systems and ceramic fiber linings and by modifying heat treating cycles. In a heat treating process, the total energy supplied is distributed into 1) the energy available to heat the work, 2) the energy lost with flue gases, and 3) the energy lost through equipment. Additional energy is needed for the generation of heat treating atmospheres and for maintaining flame curtains. Any means of improving number 1) above means increased efficiency and, in turn, dollars saved. Recuperators, as heat recovery systems, preheat the combustion air reducing number 2) above. Ceramic fiber linings are expected to reduce number 3) above. Temperatures at which heat treating is conducted can be lowered to the minimum allowed by basic metallurgical principles. Results of experiments related to recuperation, ceramic fiber linings and modification of heat treating cycles are presented.
