The common measures to reduce energy consumption for coating drying chamber were described.According to the characteristics of low temperature drying process of solvent-based coatings for structural parts, the infrared radiation waste heat utilization technology was provided. The waste heat generated by single-station infrared radiation heating was used to heat the air near the station, and at the same time meeting the coating curing requirements of dual-station structural parts. The results showed that the technology could meet production rhythm requirements, reduced the drying energy consumption by more than40% in comparison to the heated air circulation, and was popularized and applied.
