摘　　要：运用元素势能法对乙醇重整富氢混合气的燃烧与排放性能进行了理论分析,计算结果表明:可实现稀燃的乙醇重整富氢混合气能有效地降低NO,CO和CO2排放;对于稀乙醇重整富氢混合气,在相同过量空气系数下,其绝热火焰温度、NO和CO的排放随乙醇重整率的变化不超过1%,CO2的排放随重整率的增大而下降3%.The combustion and emission property of ethanol reformed hydrogen-rich synthesis gas was calculated using element potential method.The result proves that the ethanol reformed hydrogen-rich synthesis gas has good effect on reducing CO emissions,NO emissions and CO2 emissions because of lean combustion realization;the adiabatic flame temperature,CO emissions and NO emissions of the lean fuel-air mixture have no obvious change and reduce no more than 1%,CO2 emissions are reduced 3% along with the ethanol reformed ratio increasing under the same fuel-air mixture coefficient of excessive air.
