摘要： A cathodic protection system for use with a wood veneer dryer is provided. The system includes a DC power supply and an anode mounted inside the dryer in a position to be electrolytically coupled to metallic structures or surfaces inside the dryer when an electrolytic medium is present inside the dryer. The electrolytic medium comprises a high-humidity atmosphere. A method for reducing the corrosion of metallic structures or surfaces inside the dryer is further provided. The method comprises mounting an anode inside the dryer in a position to be electrolytically coupled to the metallic structures or surfaces inside the dryer when an electrolytic medium is present. Wood veneer is conveyed through the dryer and heated to a temperature sufficient to produce a high-humidity atmosphere inside the dryer. A controlled amount of current is supplied by the DC power supply to electrolytically couple the anode to the metallic structures or surfaces.
