Combustion Characteristics of Ternary Blends of Ethanol Spray/Ammonia/Methane
A swirl spray burner is used to measure and analyze the flame structure,chemiluminescence signals of OH*and NH2*,flame spectra and pollutant emissions during combustion,while examining the effects of varying methane,ethanol and ammonia mixture fuel composition and atomizing air-to-liquid ratios(ALR)on combustion and the trends of NO,NO2and CO emissions.Even though the use of ammonia results in high NOx emissions,the use of ternary blends for co-combustion,especially when ethanol mole fraction is high,the CO and NO emissions can be reduced.Within the equivalence ratio of 0.45～0.70,increasing the ALR results in more complete spray at-omization,which promotes mixing of fuel vapour with gas,leading to improved combustion and subsequently re-duced CO emissions.The use of ternary blends and control the combustion parameters are measures that enable ef-fective ammonia combustion,which serves as a guide for pollutant emission reductions and ammonia utilization for the industries.
