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.
