Zink Korner cuts energy consumption in galvanizing by 15 percent Efficient furnaces for hot dip galvanizing For galvanizing at temperatures between 450 and 460 °C, Zink Körner has developed its new RECU- TEC hot dip galvanizing technology, which allows the input energy to be recovered directly in the furnace. These furnaces are equipped with a steel tank and natural-gas fired flat flame burners. Controlled waste gas flow takes the heat in the furnace exactly where it is needed. The new RECU-CHANNEL recuperative heat exchanger system may achieve energy savings of more than 15 percent in batch-parts, wire and small-parts galvanizing. In typical batch-parts galvanizing plants, this may result in approx. 30,000 euros saved on natural gas costs every year.
