Hydrogen injection for enhancing combustion stability in gas turbine systems

A hydrogen injection device (1) includes an injector assembly including an outer conduit (5) configured to feed a flow of a mixture (3a) of air and fuel to a combustion chamber (2a) of a combustor. At least one swirler (3) may be positioned in the outer conduit (5) to facilitate a swirling output of the air-fuel mixture (3) a into the combustion chamber (2a) such that the output fuel-air mixture comprises a swirling output flow (12). A stream of hydrogen may be passed through an internal hydrogen injection conduit (7) to be output into a combustion chamber (2a) for injection in the combustion chamber as a stream of hydrogen injection. 一种氢气喷射装置(1)包括喷射器总成，所述喷射器总成包括外部导管(5)，所述外部导管被构造成将空气与燃料的混合物(3a)的流进给到燃烧器的燃烧腔室(2a)。至少一个旋流器(3)可定位在外部导管(5)中以有利于将空气-燃料混合物(3)a的旋流输出到燃烧腔室(2a)中，使得所输出的燃料与空气的混合物包括旋涡输出流(12)。可使氢气流经过内部氢气喷射导管(7)，以输出到燃烧腔室(2a)中从而在所述燃烧腔室中作为氢气喷射流进行喷射。
