Can-Eng Furnaces International Ltd. announced the successful start-up of an atmosphere roller-hearth reduction furnace at North American Höganäs in Niagara Falls, N.Y. The electrically heated unit has the capability of reducing iron-oxide powder to sponge iron in a 100% hydrogen environment flowing at high capacity. In addition to the furnace, Can-Eng supplied an H2 recycle system consisting of an energy-efficient heat-recovery unit, spray towers and auxiliary equipment for the purposes of decreasing the dew point of the process hydrogen atmosphere. A preheat furnace system was also supplied to heat the recycled hydrogen to near process temperature.
