Combustor nozzle for pure hydrogen and hydrogen-rich gas turbine and use method of combustor nozzle

The invention discloses a burner nozzle for a pure hydrogen and hydrogen-rich gas turbine and a use method of the burner nozzle, and relates to the field of gas turbines, in particular to the burner nozzle for the pure hydrogen and hydrogen-rich gas turbine and the use method of the burner nozzle. The fuel injector is arranged in the air channel and used for injecting fuel into the air channel. The invention has the advantages that the specific main flow velocity is matched with the proper jet flow momentum ratio of fuel to air, so that stable anchoring flame can be formed, and meanwhile, backfire can be effectively prevented; and the residence time of the small flame is short, and the periphery of the small flame is wrapped by abundant air, so that the emission of NOx can be greatly reduced. 本发明公开了一种纯氢及富氢燃气轮机用燃烧器喷嘴及其使用方法，本发明涉及燃气轮机领域，具体涉及一种纯氢及富氢燃气轮机用燃烧器喷嘴及其使用方法，包括：空气通道和燃料喷孔，燃料喷孔包括至少一个，设置于空气通道用于向空气通道内喷射燃料；其好处在于：特定的主流速度、配合恰当的燃料与空气射流动量比，可以形成稳定的锚定火焰，同时有效防止回火发生；小火焰停留时间短、且其四周被充裕的空气包裹，可以大大降低NOx排放。
