Abstract
This paper presents results of the application of the Two-Stage Lagrangian (TSL) model of Broadwell and Lutz to the basic and advanced rebuming processes in a 300 kW natural gas fired Boiler Simulator Facility (BSF). The injection of the rebuming fuel and overtire air is modeled as independent deflected jets in crossflow and the TSL model is applied while each jet completely mixes with the main flue gas stream of the boiler. The entrainment rate to the jet, which is required as a model input, is derived from control volume analysis using the experimentally determined jet-trajectory. The comparison with the experimental data shows good agreement for relatively high reburn zone stoichiometric ratios (SR~0.99) while the removal of NO is overestimated for richer conditions (SR~0.95 or lower). The model in general follows the trend observed in the experiment and is able to quantitatively and rapidly predict the NO removal in the gas reburning process.
