Description Paper from the AFRC 2018 conference titled Emission Characteristic Map and Optimization of NOx in 100 MW Staged Combustion Once-Through-Steam-Generator (OTSG)
Abstract In the present paper a generalized methodology to reduce emission from a staged combustion burner in a typical Once-Through-Steam Generator is outlined. Initially Computational Fluid Dynamics (CFD) tools were used to generate an emission characteristics map (ECM) of the combustion system and it was used then as a guideline towards efficient characterization and optimization of the OTSG in during a field testing. It was demonstrated that for a staged combustion system, there exists a unique ECM subject to the fuel deliver pressures at core, inner and outer header, respectively; and with the help of the ECM the global minima for NOx emission can be successfully identified and achieved. This method of emission reduction based on engineering calculation was found to be cost-effective compared to costlier conventional methods like Flue-Gas Recirculation (FGR).
