摘要

一氧化碳鍋爐在煉油製程中占有非常重要的角色，它可以將再生器中的CO熱能回收再利用，所產生的蒸汽可提供給其它設備使用，其操作溫度相當高（可達1200℃），因此，會產生一氧化碳鍋爐內外部問題，其停車檢查維修所造成之生產線損失每日以億元起計，而其所潛藏的工安與環保問題更是不容忽視，輕則造成設備的損壞而導致生產線停擺，重則造成人員的傷亡與環境的汙染，本研究即在此背景下針對一氧化碳鍋爐的三維熱流場進行一系列的詳細探討，本文以增厚耐火泥與裝設導流錐對於一氧化碳鍋爐熱傳流場之影響作為主要探討內容，文中針對不同之耐火泥厚度及不同之導流錐角度對於流場溫度及壁面摩擦係數之影響進行深入探討與比較，期能改善一氧化碳鍋爐之操作安全及使用壽命。

CO boiler plays an important role in the petroleum-refining process. It can retrieve the thermal energy of CO from the regenerator for application. CO boiler utilizes the burning gas (CO) from the regenerator as fuel. Then CO reacts to form CO2 and release large amount of heat. The hot flue gas then flows through the superheater section and exchanges heat with water in the pipelines to produce superheated steam which can be used by other equipments. The operating temperatures in a CO boiler can be as high as 1200℃. This can result in the interior or exterior problems of a CO boiler. The loss caused by shutdown/inspection/maintenance of a CO boiler can be hundreds of million＄NT per day. Furthermore, the potential threats of safety and environmental protection can not be ignored. In this study, the influences of refractory thickness and guide cone angle on the heat transfer and fluid flow in a CO boiler are discussed. The purpose of this study is to improve the operation safety and service life of a CO boiler.
