FIELD: recovery of heat of high-temperature gases after heat-treatment furnaces. SUBSTANCE: system includes furnace, flue, convective loop recuperator, and distributing and accumulating collectors in which moving partitions dividing recuperator into independent tubular elements are installed. It allows use of given system for heating of air intended for burning and for air heating in amount required for heating of department. In this case, heat exchange conditions are preserved for both air and products of burning. EFFECT: higher efficiency. 2 dwg |
