ABSTRACT
This paper reports results of NOx measurements carried out on a gas fired furnace using radial fuel injection. The data consists of a complete mapping of NOx concentration in the furnace under variable swirl conditions. Swirl produced locally higher NOx concentrations but little overall increase. Measured stack NOx variations with burner input conditions indicate that, for this system, operating with a fuel-rich mixture is more effective in suppressing NOx formation than with excess air operation. The data is needed for testing and developing theoretical models. Theoretical predictions of the overall NOx formation are made using a well-stirred reactor model based on the Zeldovich mechanism with account for the species concentration fluctuations. The model predictions compare satisfactorily with the measurements
