    Abstract
  • A dry-type low emission （DLE） micro gas turbine combustor with medium and low calorific value biomass gas was studied.The experimental test and numerical simulation of pollutant generation characteristics at different positions of fuel nozzle were carried out.The influences of nozzle position on fuel air mixing uniformity and NOx generation characteristics were obtained.The results showed that：adjusting the fuel distribution ratio and the position of the fuel nozzle can affect the emission characteristics of the combustion chamber，and there was a fuel distribution ratio that made the NOx emission the lowest；the uniformity of the fuel and air mixture was the main factor affecting the NOx generation；NOx was mainly produced in the duty combustion area，and the NOx mass concentration can be reduced to 7.6 mg/m3 by adjusting the fuel distribution ratio and the position of the fuel nozzle.
