The reduction of NOx formation in natural gas burner flames

摘要: Abstract Natural gas is widely used in domestic and commercial central heating units because it a clean fuel. However, some NOx produced more stringent legislation on emissions has been proposed, there considerable interest designing combustion chambers to give even lower emission. The burners such use multi-jets the zones resultant temperature, composition flow fields have complicated structures. can be reduced by their optimization. Another low-NOx strategy involves utilization of porous radiant surface combustors. In present work these two systems investigated experimental data are presented as an aid understanding controlling factors for thermal prompt NOx. both cases formation modelled chemical reaction scheme NO. temperature were CFD package, FLUENT, predicted with post-processing package. value this method design technique demonstrated. It also gives indication strategies required chambers.
