A SIMULATION FOR PREDICTION THE NITROGEN OXIDE EMISSIONS IN LEAN PREMIXED COMBUSTOR

Abstract

The development of chemical reactor models to predict NOx emission is very important for the modern combustion system design. In this study, chemical reactor networks (CRN) models are constructed base on the computational fluid dynamics (CFD). The boundary and operating conditions used for these CRN model reflect the typical operating conditions of the lean premixed gas turbine combustor. The global mechanism has been developed by GRI 3.0 in the UW chemical reactor code [2]. For reliability of the predictive model, the model was analyzed and compared to the experimental test combustor.
