Abstract:
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.
