摘要:
【目的】将氢气与天然气混合燃烧有助于能源过渡的顺利开展。在接近吹熄极限的情况下向受限空间中注入大量燃料，一旦发生吹熄，燃料与空气混合后将在室内积聚，极易达到爆炸极限而引发爆炸，因此，准确预测掺氢天然气吹熄极限对氢能安全应用具有重要意义。【方法】搭建了掺氢天然气吹熄特性实验装置，研究了掺氢天然气射流扩散火焰的吹熄极限，分析了掺氢比、喷嘴直径对掺氢天然气吹熄压力、吹熄速度的影响。【结果】与纯天然气相比，掺氢后射流扩散火焰的稳定性更高，扰乱火焰时需要更大的管内压力；同一种燃料在大喷嘴直径工况下吹熄速度更快，这是因为在大喷嘴直径时射流雷诺数及火焰传播速度更快，需要更快的射流速度才能使火焰吹熄；掺氢比越大，通过增大喷嘴直径以获得更快吹熄速度的效果越明显，喷嘴直径由2mm增至10mm时，掺氢比由10％增至50％所致吹熄速度的增幅由1.88倍增至2.81倍。考察了将基于烃类燃料吹熄速度的经验关联式扩展到掺氢火焰的适用性，并基于Damk?hler数提出了适用于掺氢天然气的吹熄速度预测模型。【结论】在燃烧器设计中，对于期望获得较快吹熄速度的掺氢燃烧器，可考虑通过适当增加燃烧器的喷嘴直径来扩大安全燃烧范围。研究成果对明确掺氢天然气火焰稳定性机理及其在工业燃烧器设计中的应用具有重要意义。（图6，表3，参25）
Abstract:
[Objective] The mixed combustion of hydrogen and natural gas offers a viable approach to facilitating the energy transition. When a substantial amount of fuel is injected into a confined space approaching the blowout limit, the accumulated mixture of fuel and air can easily reach the explosion limit, leading to an explosion in the event of a blowout. From this perspective, it is of great significance to accurately predict the blowout limit of hydrogen-doped natural gas for the safe application of hydrogen energy. [Methods] This study aimed to investigate the blowout characteristics of hydrogen-doped natural gas using a specially designed experimental setup. The blowout limit of jet diffusion flames fueled by hydrogen-doped natural gas was explored, and the effects of hydrogen blending ratios and nozzle diameters on the blowout pressure and velocity were analyzed. [Results] Compared with pure natural gas, hydrogen-doped natural gas demonstrated enhanced stability in jet diffusion flames, with flame turbulence occurring only at higher pressures within the pipeline. Moreover, larger nozzle diameters resulted in higher blowout velocities when the same fuel was burned, due to the increase in the Reynolds number and flame propagation velocity in the jet flow. This necessitated higher jet velocities to blow out the flame. Increasing hydrogen blending ratios had a more pronounced effect on raising the blowout velocity when larger nozzles were used. Specifically, the blowout velocity increased from 1.88 times to 2.81 times, as the hydrogen blending ratio increased from 10％ to 50％ and the nozzle diameter changed from 2 mm to 10 mm.Further exploration examined the applicability of extending the empirical correlation based on blowout velocities for hydrocarbon fuels to hydrogen-doped flames. Additionally, a predictive model for blowout velocity based on Damk?hler numbers (Da) was proposed for hydrogen-doped natural gas. [Conclusion] For the design of hydrogen-doped burners aimed at achieving higher blowout velocities, it is recommended to appropriately increase the nozzle diameters, which correspond to expanded safe combustion ranges. The research findings provide valuable insights into understanding the flame stability mechanisms of hydrogen-doped natural gas, which are significant for applications in the design of industrial burners.
