High-temperature oxygen generation device and high-temperature oxygen generation method

Abstract

The object of the present invention is to provide a high-temperature oxygen generation device and a high-temperature oxygen generation method which can efficiently supply preheated high-temperature oxygen gas regardless of pressure conditions from normal pressure to high pressure, without requiring upsizing or expansion of the equipment, and the present invention provides a high-temperature oxygen generation device () in which a high-temperature gas (G) and an oxygen gas (G) to be heated are mixed to generate a high-temperature oxygen gas (G), wherein the high-temperature oxygen generation device () includes a burner () which generates the high-temperature gas (G), and a preheating chamber () which is provided on the downstream side of the burner () and mixes the high-temperature gas (G) and the oxygen gas (G) to be heated, and the burner () includes a combustion chamber () which forms a flame by a fuel gas (G) and an oxygen gas (G) for combustion, a fuel flow path () which supplies the fuel gas (G) into the combustion chamber (), a first oxygen flow path () and a second oxygen flow path () which supply the oxygen gas (G) for combustion into the combustion chamber (), and a flow path () for oxygen to be heated which communicates with the preheating chamber (), and supplies the oxygen gas (G) to be heated toward the preheating chamber ().
