摘要：

绿氨与煤基燃料混燃作为一种可行的燃煤机组碳减排路径，分析研究全链条CO₂减排量不仅有利于推动绿氢和绿氨行业的发展，有效促进绿氢和绿氨的消纳，还有利于推动氨煤混燃发电技术的发展。以可再生能源发出的绿电制成绿氨并在燃煤机组上实现氨煤混燃发电为情景，对全链条CO₂减排量进行测算，结果表明，采用445 GW·h绿电制备绿氨并在燃煤机组上进行掺烧发电，其全链条CO₂减排量可达10.07 万t/a，绿电CO₂减排量约226.29 g/（kW·h）且每年节省约956.65万元的碳减排成本。

Abstract:

Co-firing green ammonia with coal-based fuels is a feasible carbon reduction pathway for coal-fired power plants.Analyzing carbon reduction across the entire chain not only facilitates the development of the green hydrogen and green ammonia industries and effectively promotes their efficient utilization，but also supports the advancement of ammonia-coal co-firing technology.In a scenario where green ammonia was produced using renewable energy-powered green electricity and co-fired of ammonia with coal in coal-fired power plants， the total CO₂ reduction throughout the chain was calculated.The results showed that using 445 GW·h of green electricity to produce green ammonia and co-firing it in coal-fired units achieved a total CO₂ reduction of 100.7 thousand tons/year.The CO₂ reduction per unit of green electricity was approximately 226.29 g/（kW·h），and annual carbon reduction cost savings were estimated at 9.5 665×10⁶ yuan.
