摘　　要：为评估未来使用可再生能源合成的无碳氨的氨煤混燃机组在实际应用中的技术经济性,建立了无碳氨合成成本计算方法以及煤电机组氨煤混燃平准化电力成本(LCOE)经济模型。基于各环节的投资成本与耗能情况,进行了平准化无碳氨成本的计算。结果表明:在当前可再生发电成本及技术投资情况下,无碳氨成本高于煤化工合成氨成本,且可再生发电成本为无碳氨成本的主要影响因素;考虑碳税情况下,在制氨成本以及碳排放成本不会产生较大改变的近未来范围内,氨煤混燃相较于传统煤电不具备经济优势;无碳氨价格是影响LCOE的主要因素。In order to evaluate the techno-ecnomic of the future practical application of ammonia-coal co-combustion power unit composited by green ammonia,a method for calculating green ammonia synthesis cost and a model for levelized cost of electricity(LCOE)were established.Based on the investment cost and energy consumption of each process,the LCOE of green ammonia cost was calculated.Results show that under the background of current renewable power generation cost and technology with relatively high-investment,the cost green ammonia is higher than the synthetic ammonia from coal chemical industry,and the renewable power generation cost is the considerable factor affecting the cost of green ammonia.Considering the carbon tax,In the near future,the green ammonia production cost and carbon emission cost will not change significantly,ammonia-coal co-firing has no economic advantage over traditional coal power,and the price of green ammonia is the main factor affecting LCOE.
