High Temperature Recuperation for Steel Mill Soaking Pits

A new system has been proposed for the recuperation of waste heat energy in steel mill soaking pit furnaces. The new system offers efficiency increases from 130% to 360% above conventional recuperation systems. This is possible through the combination of a low leakage, compact ceramic recuperator and a highly efficient, low cost metallic unit. Included in the advanced design is a newly developed ultra high temperature preheated air multi-fuel burner and an improved system for air/fuel ratio and temperature control.
