Abstract

One of the conventional gas burners has nowadays been used for ladle preheating. As a ladle is one of the open-type furnaces, however, it causes to consume much fuel because of high temperature of exhaust gas from the ladle and the exhaust gas passing through ladle cover makes it worsen a working environment nearby. Therefore, the objective of this study is to develop the recuperative burner system applying for an existing teeming ladle , which is integrated with burner, recuperator and eductor as one of the new type combustion equipments and has many advantages of simple installation, compactness and easy control, especially a great deal of energy saving through the waste heat recovery from exhaust gas. The contents of the study is to design, manufacture of recuperative burner system and to perform its tests experimentally after applying to the teeming ladle in the capacity of 100 ton. Its heat release rate is 1,700,000 kcal/h with COG(Cokes Oven Gas) as fuel gas. The test items are the temperature distribution inside the ladle and the preheated air temperature change depending upon the exhaust gas. Nox, exhaust gas analysis and noise.
