Abstract
Ceramic shell and tube recuperators capable of providing up to 1800oF (980oC) preheated combustion air and operating at process gas inlet temperatures of up to 2800oF (1540oC) have shown themselves to be cost effective waste heat recovery devices. Full utilization of the heat recovered by such ceramic recuperators requires burners designed to accept combustion air preheated to recuperator design levels and economical high temperature ducting. Energy savings, product development, and maintenance experience on installations in the steel forging industry are discussed. Packaged furnace systems and non-forging applications of such recuperators are discussed.
