为探究传统天然气燃气轮机对氢气燃料的适应性，开展现役某型天然气燃气轮机燃烧室掺氢燃烧性能试验研究。本文对燃烧室在使用不同掺氢比燃料时的性能进行了试验，设计了一种监测燃烧室回火方法，测得了燃烧室掺氢燃烧的回火情况、污染物排放、出口温度分布、总压损失等性能。试验结果表明：燃料中掺氢比增加，喷嘴回火风险升高；受到燃机整机参数影响，在燃机低工况更容易出现回火；燃料中掺氢比例增加，燃烧室总压损失升高，NOx排放升高，CO排放减少，火焰筒壁面温度有所升高，但分布规律几乎没有变化；在试验范围内，燃料中掺氢，对燃烧室出口温度均匀性和压力脉动几乎没有影响。

To explore the adaptability of traditional natural gas turbines to hydrogen fuel, experimental research was conducted on the combustion performance of a certain type of natural gas turbine combustion chamber mixed with hydrogen. This article conducts experiments on the performance of the combustion chamber when using fuels with different hydrogen blending ratio sand designs a method for monitoring combustion chamber tempering . The combustion chamber tempering, pollutant emissions, outlet temperature distribution, total pressure loss, and other properties of the combustion chamber during hydrogen blending combustion were measured. The experimental results show that as the hydrogen doping ratio in the fuel increases, the risk of nozzle backfire increases; Affected by the overall parameters of the gas turbine, backfire is more likely to occur under low operating conditions of the gas turbine; As the proportion of hydrogen added to the fuel increases, the total pressure loss in the combustion chamber increases, NOx emissions increase, CO emissions decrease, and the wall temperature of the flame tube increases, but the distribution pattern remains almost unchanged; Within the experimental range, the addition of hydrogen to the fuel has almost no effect on the uniformity of the combustion chamber outlet temperature and pressure pulsation.
