| 中文摘要: |
| 本研究提出一种用于预测甲烷、氢气、氨气三元燃料混合气体的度电碳排放因子的数学模型EF，用于评估不同燃料组分下，燃气轮机每产生一度电的二氧化碳排放量。以度电碳排放因子模型为基础，利用Visual Basic软件建立计算程序，输入必需数据即可计算某一燃料组分下燃料的度电碳排放量情况。当燃料气体全为甲烷（α=1）的情况下，预测的度电碳排放达到最大值0.568kg/kWh；当燃料气体全为氢气（β=1）或全为氨气（γ=1），度电碳排放因子的预测值均为最小值0。三元混合燃料占比α:β:γ=1:1:1时，较纯甲烷（α=1）燃烧的二氧化碳排放减少量达到1.318kg，二氧化碳排放减少率66.7％，该预测结果反映了在甲烷中掺混氢气和氨气对二氧化碳排放的抑制作用。 |

| This study proposes a mathematical model EF for predicting the carbon dioxide emission per kilowatt-hour factor of methane, hydrogen and ammonia ternary fuel mixture gas, which is used to evaluate the carbon dioxide emissions per kilowatt-hour of electricity generated under different fuel composition schemes. Based on the carbon dioxide emission per kilowatt-hour factor model, using the object windows established by Visual Basic software, each object window is programmed to enable users to input the necessary data end-to-end and calculate the carbon dioxide emission per kilowatt-hour of the mixed fuel at a certain proportion. When the fuel gas is all methane (α=1), the predicted carbon dioxide emissions per kilowatt-hour reach the maximum value of 0.568kg/kWh. When the fuel gas is all hydrogen (β=1) or all ammonia (γ=1), the predicted value of the carbon dioxide emission factor per kilowatt-hour is the minimum value of 0, and the proportion of ternary mixed fuel α: β: γ=1:1:1, the reduction in carbon dioxide emissions compared with pure methane (α=1) combustion reaches 1.318kg, and the reduction rate of carbon dioxide emissions is 66.7%. This prediction result reflects the inhibitory effect of blending hydrogen and ammonia into methane on carbon dioxide emissions. |
