Abstract ：
氨部分预分解是改善氨的燃烧性能的有效手段,但对于氨预分解条件的影响仍缺乏系统的研究.该文针对基于氨预分解策略的氨扩散燃烧装置开展数值模拟研究,以分析氨预分解比例、当量比和氨分解余热对燃烧及污染物排放特性的影响.结果表明,随着氨预分解比例提高,火焰温度提高,火焰高温区更靠近喷嘴,NOx排放量下降;NO排放在NOx中占主导,并随着当量比的提高先增大后减小;N2O排放主要发生在低氨预分解比例、低当量比条件下,在氨预分解比例达到50％后基本消失;利用氨分解余热预热燃料有助于稳定燃烧,并在氨预分解比例不超过30％时,明显减少氨泄漏而未增加NOx排放.研究表明,提高氨预分解比例和当量比能有效改善氨燃烧及污染物排放特性,而在小比例氨预分解条件下应充分利用氨分解的余热.

Abstract ：
As a carbon-free hydrogen (H2) carrier with the advantage of liquefaction storage and transportation, ammonia (NH3) is regarded as a competitive clean energy carrier for H2 production and power generation. This work designs a novel NH3-fueled hybrid power generation system, which combines ammonia decomposition reactor (ADR), proton exchange membrane fuel cell (PEMFC) and micro gas turbine (MGT) together with thermochemical recuperation for ADR. A system-level thermodynamic model has been developed to evaluate system performance with different optimization strategies. The model calculation reveals that the NH3 decomposition temperature drop from 500 degrees C to 350 degrees C can increase the energy efficiency from 33.5 % to 43.2 %, and two improved integration strategies have therefore been proposed. Mixing a part of NH3 with the exhaust gas from PEMFC anode to fuel MGT can reduce the NH3 decomposition demand and makes better use of waste heat from MGT. Integrating ADR with MGT combustor can lower the exhaust gas temperature and the efficiency loss when using high temperature NH3 decomposition catalyst. Both strategies can improve the system energy efficiency, to about 40% and 44% when NH3 decomposition temperature is 500 degrees C and 350 degrees C, respectively, and demonstrate better flexibility in adapting to changes in NH3 decomposition temperature.

Abstract ：
Ammonia is a carbon-free energy carrier with 17.6 wt% hydrogen content. The design of an efficient and compact ammonia decomposition reactor based on low-temperature catalysts is the key to realizing industrial hydrogen production from ammonia. In this work, a multiscale model was developed by bridging the particle-scale characteristics of catalysts and reactor performances, to fully comprehend the ammonia decomposition process. The effects of catalyst porosity and pore diameters on the reactor size, precious metal loading, and the profile of temperature and heat flux were systematically evaluated. An improved reactor design was further proposed by applying the segmented reactor packed with two-stage egg-shell-type low-temperature catalysts, which decreased the precious metal usage by 61.6% and the temperature drop by 42.9 K. This segmentation strategy balanced the reaction rate and heat flux, indicating a significant potential in highly efficient, economical, and reliable hydrogen production from ammonia.
