Investigation of pollution formation mechanism through the application of a diesel surrogate model for developed for a diesel-operated gas turbine system

Diesel fuel is known as a key energy supply source for power plant technology, particularly in gas turbine systems. Despite of its importance, the environmental issues regarding the combustion process are still a matter of concern, particularly regarding the emission of soot particulate matter and nitrogen oxides. This requires identification of the fuel combustion which proceeds through kinetic modeling procedure. To this end, the recently published model of the authors’ group for diesel combustion was implemented to further investigate fuel combustion behavior. This includes mainly numerical studies of the primary ignition phenomenon, which directly elevates the nitrogen oxide emission at the beginning of the run-time of gas turbine system. More else, the production of poly aromatic hydrocarbons, as the main soot precursors is investigated. This is achieved through simulation of the related species concentration profiles from diesel flame under certain experimental condition, similar to operational condition of a real gas turbine unit.
