Abstract

A novel external combustion-air adjustment method (ECAM) is proposed to control the reaction zone fuel-air ratio under off-design loads. The combustion-air is redistributed by reducing the reaction zone airflow via ECAM. Investigations are carried out to characterize the combustion dynamics and emission properties of a micro gas turbine (MGT) combustor when ECAM is used. The results show that ECAM is beneficial to control the huge increase of CO emission under off-design loads, but also present the risk of the NOx increase. The detailed analyses reveal that ECAM has a slight effect on the overall internal flow field, but leads to significant velocity increase close to the jet shear layers, and thus results in a longer reaction zone residence time, especially for the burned gas generated by the pilot flame. It directly causes the increase of NOx emissions by 29.6% with the decrease of load from 100% to 50%. Furthermore, a small-scale adjustment (from 9.0% to 8.2%) of pilot fuel proportion shows a good reduction of NOx emissions about 2.7 ppmv and 2.6 ppmv by shortening residence time about 6.72 ms and 3.68 ms of burned gas in the rection zone under 75% and 50% load, respectively.
