| Abstract (English): |
To address the energy shortage and meet the requirements of environmental protection policies, the feasibility of premixed fuel 1 (natural gas (NG), syngas, and hydrogen) and premixed fuel 2 (NG and hydrogen) in the tobacco curing system was studied. First, according to the law of conservation of energy and mass, a tobacco leaf curing system model was established. Then, the interchangeability index of the premixed fuels was analyzed, and their volume ratios were obtained. Finally, a numerical simulation analysis of the premixed fuel combustion was conducted based on the indicators of emission, temperature, and economy. On this basis, the comprehensive performance indexes of the system composed of different premixed fuels were evaluated. The results obtained indicate that with the increase in the hydrogen volume ratio in premixed fuel 1, NOx emissions will gradually increase. Moreover, with the increase in the hydrogen volume ratio in premixed fuel 2, CO emissions will gradually decrease. Because premixed fuel 2 contains more hydrogen than premixed fuel 1, CO emissions are reduced by 9. 39% and 16. 72% as compared with the NG system when the volume ratio of NG to hydrogen is 95: 5 and 90: 10, but the NO emissions of the latter are beyond the acceptable range. Finally, the overall performance is good when the volume ratio of NG to hydrogen is 95: 5, and the volume ratio of NG to syngas to hydrogen is 90: 5: 5. [ABSTRACT FROM AUTHOR] |

为解决能源短缺和满足环保政策要求，分别对预混燃料 1（天然气、合成气和氢气）和预混燃料 2（天然 气和氢气）在烟叶烘烤系统中的可行性进行了研究．首先，根据能量和质量守恒，建立烟叶烘烤系统模型．然 后，对预混燃料的互换性指标进行了分析，得到燃料初步预混的体积比例．最后，从排放、温度和经济性等指 标对预混燃料的燃烧进行了数值模拟分析．在此基础上，对不同预混燃料构成的系统的综合性能指标进行 了评价．结果表明：随着预混燃料中氢气体积比例的增加，NOx 的排放会逐渐增加；随着预混燃料 2 中氢气 体积比例的增加，CO 的排放会逐渐降低．由于预混燃料 2 中含有较多的氢气，当天然气与氢气体积比为 95:5 和 90:10 时，其 CO 排放较 ＮＧ系统分别下降了 9.39％ 和 16.72％，但后者的 NO 排放超出了可接受范围． 研究发现，当天然气与氢气体积比为 95:5，以及天然气、合成气与氢气体积比为 90:5:5 时综合性能更优． [ABSTRACT FROM AUTHOR] |
