Abstract: In view of the structure and characteristics of coke tower wrapped insulation and combining with the overall settlement of coke tower (C2101/2) on-site insulation of a certain enterprise, this paper obtained the causes of general overheating of coke tower insulation through on-site inspection and infrared scanning analysis. Then it proposed corresponding solutions. The paper also analyzed and discussed the technologies related to the installation process of coke tower wrapped insulation. After dismantling and replacing the tower insulation with the improved construction technology, the over-temperature has been controlled effectively, which has guaranteed the long-term, high-efficiency, safe and smooth operation of the coke tower system. This case can provide reference for the construction quality improvement of coke tower wrapped insulation.

Key words: wrapped insulation, over-temperature, installation, coke tower
