Abstract

Numerical studies were conducted to investigate effects of fuel configuration on NO_xformation characteristics within a staged lean premixed gas turbine combustor. Use the extended Zeldovich mechanism to calculate thermal NO, four-step Fenimore mechanism to calculate prompt NO, two-step reversible elementary reactions to calculate NO from N₂O-intermediate route. The results showed that the trend of total NO_x emission of the combustor derived from numerical studies was much coincided with the trend through experiment under different fuel configuration condition. Using these numerical methods, the paper investigated that Zeldovich mechanism, Fenimore mechanism, N₂O-intermediate mechanism, respectively contributed to NO formation in different fuel configuration condition, and discussed the effects of temperature on the formation of thermal NO, prompt NO, and NO from N₂O-intermediate route.
