燃煤锅炉氨煤混燃技术的研究进展OA北大核心CSTPCD

It is crucial to achieve the goals of carbon peaking and carbon neutrality and reduce carbon emissions to address global climate change.Ammonia gas has the advantages such as low transportation and storage costs,high safety,and zero carbon emissions during combustion.The mixed ammonia-coal combustion technology of coal-fired boilers has been highly valued by various sectors of society.The low-carbon and low-nitrogen combustion processes of coal-fired power plantswere reviewed,and the flame propagation characteristics of ammonia fuel were introduced.The impact of mixed ammonia-coal combustion technology on NOx generation from multiple perspectives such as ammonia injection position,ammonia blending ratio,overfire air,and equivalence ratio was analyzed.The impact of mixed ammonia-coal combustion on the performance of coal-fired units was discussed.It points out that mixed ammonia-coal combustion technology is a low-carbon combustion technology with great development potential,which is beneficial for achieving the goals of carbon peaking and carbon neutrality in China.
