Carbon dioxide (CO 2 ) emissions present a significant ecological challenge due to their detrimental effects on the climate. Ammonia (NH 3 ) is a prospective fuel to be cofired with coal to control CO 2 emissions without incurring substantial infrastructure changes. The technical potential of NH 3- coal cofiring in combustion behavior, emission control processes, and formation of nitrogen oxide (NO x ) is discussed in this review article. The combustion of NH 3 is promising for decarbonization, although it is associated with challenges in controlling NO x emissions. Injection of NH 3, air staging, and optimization of the burner have been put forward to restrict NO x and N 2 O formation without compromising combustion efficiency. Recent studies suggest that cofiring NH 3 in controlled ratios can restrict CO 2 emissions without compromising NO x emissions beyond regulatory limits by utilizing efficient injection strategies and overfire air management. This study integrates a fundamental understanding of the burner design, combustion kinetics of coal-NH 3, and emissions control strategies, while assessing its potential as a cleaner energy production fuel. The findings highlight that while incorporating NH 3 offers a tempting decarbonization pathway, additional efforts are needed to improve combustion and fortify emission control strategies, emphasizing the urgency of this research.
