摘要

为了应对日益严峻的气候变化问题

在全球碳减排的大背景下

无碳燃料的发展面临着巨大的机遇。氨能源的开发是实现"双碳"目标的有效措施

在10 kW(输入功率)甲烷掺氨实验台上

进行了甲烷和氨气掺混扩散燃烧实验研究

并且结合化学反应器网络(CRN)分析了不同输入功率、当量比和掺氨比例等条件下的氨气/甲烷燃烧和排放特性。结果表明:甲烷对氨气的燃烧起到了明显的促进和稳定作用

然而仅掺入热值分数为9.1%的氨气即可使NO排放量急剧增加;采用轴向空气分级策略可显著降低NO

排放和未燃氨气的逃逸

并且随着氨气比例的提高

燃烧室出口温度升高。

Abstract

In order to solve the increasingly serious problem of climate change

the development of carbon-free fuels is exposed to a huge opportunity on the background of global carbon emission reduction. Meanwhile

the development of ammonia energy is an effective measure to achieve carbon peak and carbon neutrality. On a 10 kW (input power) laboratory bench with ammonia-blended methane

experimental researches were conducted on the diffusive combustion of mixed methane and ammonia

while combined with chemical reactor network (CRN)

analyses were carried out for the combustion and emission characteristics of ammonia/methane under different input powers

equivalence ratios and blending ratios. Results show that methane has a significant effect on promoting and stabilizing the ammonia combustion

but the NO emission w

ould be dramatically increased with the ammonia heat value fraction of only 9.1%. The strategy of axial air staging can be applied to reduce the NO

and unburned NH

emissions

and the combustion chamber outlet temperature can be increased with a increase of ammonia-blended proportion.
