Abstract

To obtain the ignition performance of an integrated inclined combustor, we perform an experimental study on the ignition performance of an inclined combustor under various ignition positions, inlet flow rates, and fuel air ratios (FARs). The experimental results reveal the following. 1) During ignition at I1, the inclined combustor presents the best ignition performance. 2) The forward propagation process of flame along the swirler's inclined direction easily realizes flame propagation, whereas the backward flame propagation process in the swirler's inclined direction is difficult to achieve; forward and backward flame propagations exhibit evident differences. 3) The diffusion propagation of swirl flames at the ignition head is the main means swirl flames are generated at the nonignition head. 4) During the ignition process, the combustion intensity increases with the increase in FAR and decreases with the increase in inlet flow rate. 5) The successful ignition time decreases with the increase in inlet flow rate and FAR.

综合倾斜燃烧器点火特性的实验研究

为了获得一体化倾斜燃烧器的点火性能，我们对倾斜燃烧器在不同点火位置、进气流速和燃料空气比（FAR）下的点火性能进行了实验研究。实验结果如下1) 在 I1 点火时，倾斜燃烧器的点火性能最好。2) 火焰沿漩涡器倾斜方向的前向传播过程容易实现，而在漩涡器倾斜方向的后向传播过程则难以实现；前向和后向火焰传播表现出明显的差异。3）漩涡火焰在点火头的扩散传播是漩涡火焰在非点火头产生的主要途径。4) 在点火过程中，燃烧强度随 FAR 的增大而增大，随入口流速的增大而减小。5) 成功点火时间随入口流速和 FAR 的增加而缩短。

期刊介绍： Fuel Processing Technology (FPT) deals with the scientific and technological aspects of converting fossil and renewable resources to clean fuels, value-added chemicals, fuel-related advanced carbon materials and by-products. In addition to the traditional non-nuclear fossil fuels, biomass and wastes, papers on the integration of renewables such as solar and wind energy and energy storage into the fuel processing processes, as well as papers on the production and conversion of non-carbon-containing fuels such as hydrogen and ammonia, are also welcome. While chemical conversion is emphasized, papers on advanced physical conversion processes are also considered for publication in FPT. Papers on the fundamental aspects of fuel structure and properties will also be considered.
