Zink KÖRNER flat flame burner
Zink KÖRNER is the only supplier of furnaces that use burners specifically developed for batch galvanizing. Thanks to these burners, galvanizing furnaces reach efficiencies of up to 75 percentages – which is 5 to 10 percentages better than conventional plants. Unlike the burners commonly used in the past, the gas-fired flat flame burners of the FL 20/50 type operate in a modulating mode. They are infinitely adjustable within a range of 1:10. They guarantee the same smooth and mild heating as previously only achievable by electrically heated furnaces. The control system permanently adjusts the power to the throughput rate of the furnace and avoids abrupt temperature changes, which may cause excessive stresses in the galvanizing tank structure.
