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

A high-temperature oxygen generation device in which a high-temperature gas and an oxygen gas to be heated are mixed to generate a high-temperature oxygen gas,

• wherein the high-temperature oxygen generation device includes a burner which generates the high-temperature gas, and a preheating chamber which is provided on the downstream side of the burner and mixes the high-temperature gas and the oxygen gas to be heated, and
• the burner includes:
• a combustion chamber which forms a flame by a fuel gas and an oxygen gas for combustion;
• a fuel flow path which supplies the fuel gas into the combustion chamber;
• at least one flow path for oxygen for combustion which supplies the oxygen gas 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 to be heated toward the preheating chamber,
• wherein the burner includes:
• a first oxygen flow path of the at least one flow path for oxygen for combustion which is provided on the center axis of the burner and ejects the oxygen gas for combustion on the center axis of the burner as the flow path for oxygen for combustion;
• the fuel flow path which is arranged around the first oxygen flow path, and ejects the fuel gas along the axis direction of the burner;
• and
• a second oxygen flow path of the at least one flow path for oxygen for combustion which is arranged around the fuel flow path, and ejects the oxygen gas for combustion so as to be directed toward the center axis of the burner while inclining with respect to the center axis of the burner as the flow path for oxygen for combustion;
• the flame is formed by the fuel gas ejected from the fuel flow path and the oxygen gas for combustion ejected from the first oxygen flow path and the second oxygen flow path in the combustion chamber, and
• the flow path for oxygen to be heated communicates with the preheating chamber, arranged around the second oxygen flow path, ejects the oxygen gas to be heated around the flame, and supplies the oxygen gas to be heated toward the preheating chamber.
