摘要

为了研究甲烷掺氢燃料对燃气轮机燃烧室热声振荡特性的影响

利用计算流体动力学结合系统辨识(CFD-SI)的方法对某旋流预混燃烧室进行了数值研究。在非定常CFD模拟中提取上游速度与火焰整体热释放率波动的时间序列

并通过相关性分析进行系统辨识

获取了不同甲烷掺氢比下的火焰传递函数(FTF)

并结合低阶网络模型对燃烧室热声不稳定性进行了分析。结果表明

随着体积掺氢比的提高

火焰逐渐由“V”形变为“M”形

燃烧器出口处的涡结构先形成后消失

这导致了燃烧室热声振荡特性的改变。在体积掺氢比低于30%时

火焰响应不发生较大变化

燃烧室振荡频率小幅提高; 当掺氢比在30%～60%时

火焰对低频的响应逐渐增强

对高频响应先增强后减弱

燃烧室在200 Hz附近热声模态的振荡消失

火焰稳定性增强

但高频纯声学模态被激发; 而当掺氢比达到60%时

燃烧室内重新出现热声模态的振荡。对于以天然气作为燃料的燃气轮机

适当的掺氢比能改善燃烧室内的热声不稳定性

但氢气加入会更容易激发燃烧室的高频纯声学模态

使其在高频范围内出现振荡。

Abstract

To study the influence of hydrogen-mixed methane fuel on the thermoacoustic oscillation characteristics of gas turbine combustor

a swirl-stabilized premixed combustor was numerically studied in this paper by means of computational fluid dynamics combined with system identification(CFD-SI). The time series of upstream velocity fluctuation and the overall heat release rate fluctuation were extracted from one transient CFD simulation

then the flame transfer functions(FTFs)for different hydrogen mixing ratio were obtained by correlation analysis. Furthermore

the FTFs were used in the low-order network model to analyze the thermoacoustic instability of the combustor. The results showed that with the increase of hydrogen mixing ratio

the flame gradually deforms from “V” to “M” shape

and the vortex structure at the outlet of the burner first forms and then disappears

which leads to the change of the thermoacoustic oscillation characteristics of the combustor. When the ratio is lower than 30%

the flame response does not change significantly

and the oscillation frequency increases slightly. When the ratio is in the range of 30%—60%

the flame's response to low frequency is gradually enhanced

and the response to high frequency is first enhanced and then weakened. And the thermoacoustic oscillation of the combustor near 200 Hz disappears

which means the flame stability enhanced

but a high-frequency pure acoustic mode is excited. And when the ratio reaches 60%

the thermoacoustic oscillation reappears in the combustor. For gas turbines fueled by natural gas

a proper hydrogen mixing ratio can improve the thermoacoustic stability in the combustor

but the addition of hydrogen can more easily stimulate a high-frequency pure acoustic mode of the combustor

making it oscillate in a high frequency range.
