1. Proj. Name：CPCT SRU#2 Muffle Furnace and Waste Heat Boiler

Replacement EPC Project

2. Client：CPC Tao-yuan Refinery

3. Proj. Period：Mar. 2025∼Jul. 2026

4. Proj. Description：

This Project is to replace CPCT SRU#2 three old exist equipment including Muffle Furnace (BA-3401)/ Waste Heat Boiler (BF-3401)/ and Steam Drum (FA-3403) with new ones because they have gradually become hard repaired and out of order after being operated over forty years. In order to improve the reaction effect of the Furnace, the hexagonal ceramic blocks "Vectorwall" is specially selected as the Checkerwall of the Furnace in this project. It can generate process M.P. Steam (≦20kg/cm² G) on the shell side of the WHB to achieve the purpose of energy saving and carbon reduction. In addition to upgrade with optimization including the Furnace Refractory, Checkerwall, Ferrules on WHB front tube sheet and Linings for compliance with the necessary regulations, new equipment shall follow the original equipment outline and structure design and material supply. A new set of AUTOCAD editable design drawings shall be drawn for future maintenance referenced by relevant units of the Client. After being replaced and updated, on the condition of the Furnace is operated within 1400°C, the temperature at any point on the Furnace outer wall surface shall be ≦ 300°C.
