Abstract: Some of the impurities (Br, Cl, Fuel-N, and S) in fuels can reduce the radicals (O, H, and OH) formed in the flames on combustion, thus lowering the radical mole fraction. The variation in the radical mole fraction affects the NO x emissions. In this study, the radical reducing effects caused by these impurities were modeled based on measurements of the radical mole fractions. Linear relationships were obtained between the mole fractions of the impurities in the flames and the reciprocals of the radical mol… Show more

“…Syngas is a clean fuel that has been widely used in heating furnaces and gas turbines. , It is produced from coal, biomass, or waste by gasification, pyrolysis, or reforming processes . In actual syngas, there are a certain number of nitrogen-containing components (e.g., NH 3 ) resulted from the syngas production process. NH 3 is a typical fuel-nitrogen precursor and the control of the fuel-NO x emission is essential for the combustion of ammonia-containing syngas. , The investigation on the oxidation of syngas-ammonia is crucial for suppressing the fuel-NO x emission from the combustion of actual syngas containing initial NH 3 .…”

“…Masato et al [5] successfully carried out ammonia-coal co-combustion test on a 1.2 MW pulverized coal boiler. Tsukada et al [6] studied the effect of OH radical in fuel-NO x formation during co-combustion of ammonia with hydrogen, methane, coal, and biomass. The results show in staged combustion, if the concentration of OH free radical in the fuel-rich area is too low, the decomposition of ammonia will be inhibited and the amount of NO x will increase, while the amount of NO x produced by coal-ammonia mixed combustion is lower than that of methane-ammonia at the same equivalence ratio.…”

“…Recently, NH 3 is being considered as a promising vehicle for hydrogen storage, and there is an increasing number of studies on the use of NH 3 for power generation, both in pure form , but also when co-mixed with fuels such as NG and pulverized coal. In addition to considerations like power density and efficiency, there are concerns about potential corrosion and damage to equipment, and pollutant emissions, particularly NO x , because of their known negative effects on the environment and since such emissions are strictly regulated in many countries, including the United States. Miller and Bowman and Sullivan et al have reported the main chemical formation routes of NO x from NH 3 during combustion.…”
